Rockville RBG12S Bass Gig 12" Active Powered PA Subwoofer for DJ/Pro

Ok let me tell you that The RGB15S Active Subwoofer is an amazing little package. I ordered two of these to pair with my RPG12 Active speakers for use at an outdoor festival. The Subwoofers are built very well, the carpeting of the cabinets seemed a little lacking in QA/QC but none the less was effective and clean. The input section is very user friendly and marked in such a way that it’s nearly impossible to not connect these properly. The sound quality is also impressive, I have seen various videos on Youtube that show muffled or distorted subwoofers I am assuming this is because the RGB15S units were not set up property or had signal going to them that was distorted. The playback from the sub at my events was tight and accurate. Much better than I was expecting. On a scale of 1 – 10 I would give the RGB152 an 8-8.5 rating. Definitely enough quality sound and volume for any mobile DJ indoor or outdoor venue. The RGB15S subwoofer has an onboard DPS that is pretty user friendly. Pick a disposition and slide the selector switch to the setting and you’re in business. There is also a onboard crossover with 3 crossover points, again very easy to use, pick your desired Xover point and slide the switch. I have seen many user videos & reviews of these subs that really do not do them justice. The key to setting these subwoofers (or any speaker for that matter) up correctly is having your signal source or controller set up property. Poor signal source = Poor sound. Start with the DSP set to OFF and the Xover point set to 80hz. turn the gain pot on the RGB15S to “zero” (all the way to the left) Assuming your Controller is set up and “zeroed to no more than +3db” (your digital meters are not constantly in the red, only bouncing in the orange and peaking in the red from time to time) connect your sub to the controller and play a track with reasonable bass and at full program volume. (NOTE: YOUR TOP SPEAKERS ARE OFF AT THIS POINT NO SOUND AT ALL FROM THEM). Once music is playing, slowly increase the gain (turn to the right) on your RGB15S until you hear sound coming from your sub. Continue to increase the Gain pot until you begin to hear distortion and see the clip light flash vigorously, slowly turn the gain pot back to the left until the CLIP light only quickly FLASHES on bass notes. Then Turn it a tiny bit to the left more. This should give you a good “live play back” setting on the sub. At this point connect your TOP speakers and adjust their volume accordingly. If the low end sound is not quite right, at this point you can adjust the Xover frequency on the sub, I would recommend lowering the volume when doing this. I have found that when using the RPG12 powered system (input gain set to 5 and unit volume set to 6), the 100hz setting blends the best for most music types. You can also adjust the DSP if you are looking to boost the bottom end but I have found that the DSP seems to distort the sound coming from the subwoofer and 99.9% of the time leave that set to off. I have used TWO RPG12 tops and TWO RBG15S bottoms at outdoor events in 90* Full sun conditions and ran them nonstop at peak volume for over 5 hours with no problems. The amp on the RGB15S was not even hot when the event was over. The NON POWERED pass though outputs provide for easy connection to my RPG12 tops. For the price point I am extremely impressed with the RGB15S subwoofer. The only thing I would like to see on these for the future are “recessed wheels” so you can tip and roll the subs when needed. out of the box I did have one RGB15S arrive DOA. However the Team at Rockville was quick to help resolve my issues. The initially sent me a replacement amp, when that did not fix the issue, they issued a replacement RGB15S for me and set up an RMA and return shipping label for the DOA unit. The whole return/swap took about 5 days. In closing, the RGB15S is a lot of bang for your buck. When set up properly you’ll get good sound quality with tons of volume. On board Xovers and DSP settings add value to the package. Priced at approximately $250each with free shipping (amazon or rockville site) you really cant go wrong.

All I can say is getting 2 of these subs have made my gigs sound SO much better. I don't know what took me so long to purchase them, I have seen other reviews of the RBG15S sub here in amazon where some people where "underwhelmed" by the sub. I have NO IDEA what they were listening to, but this sub will pull your house down, IF you know anything about subs in general and the fundamentals of gain/volume/crossover/boost. You might think, "well you have TWO subs, so of course they'll sound better and hit harder". While this IS true, I did my testing prior running only one sub (paired to a set of Rockville RPG 12's and it hit HARD. With both hooked up, EVERY and I do mean EVERY wall, window and fixture in my house were flexing and vibrating like crazy. It was so bad, even my garage doors were vibrating and squeaking, lol. Sub Construction - This is a very large and heavy sub, considering it is only a 15", weighing in at about 90lbs! I can't imagine getting the 18"s like I was initially planning The box is covered in carpet and has 2 slotted ports on the bottom front. There is also a blue LED on the front, so you can tell if the speaker is on (when in front of it, with no music playing). This light can be turned off. The box does not flex or creek and all the joints seem to be connected well. In order to move the sub around, I had to put them on my little mini trolly/dolly. The sub has 2 handles and these are also, like the sub, super solid. I never once was concerned about them coming off or anything. When I picked the subs up, likewise, I was never concerned about them flexing or falling apart. The sound - Like I've already mentioned, the sub is pretty powerful and if you know a thing or 2 about sub audio, you can get it sounding tight and fairly accurate. The sub has 2 ways for LINE IN/THRU being a combination XLR/1/4" port. The OUT is 2 XLR connections. For BEST sound I'd suggest using XLR from the Sub to your Tops, IF they are XLR. If your speakers are RCA only, you could do a cable with an XLR side and RCA on the other and run that form the sub to your tops. On the back is Level (aka Volume/Gain), a Crossover and Boost selector. I have my subs in the 11 O'Clock positions (-3) without any Boost options and the crossover at about 100hz. With this setting, the music my clients ask for [Reggae, House, Hip Hop, R&B, Soul and Jazz] sound GREAT. I did play with the Boost options (power and extended) for a few minutes, but these seemed gimmicky at best and fell off at higher levels, and to me sounded artificial. If you find the Bass to be over or underwhelming, you can cut that back or add it through your DJ Controller itself. I find myself adjusting it through the night depending on what I'm playing and at what time (Lounge, Dinner, Dancing). Again, I cannot over stress the importance of understanding Sub-Bass, Gains and Volumes and would suggest doing a little research on the net. If you don't have time for that, you can do as I did: 1) Avoid turning the sub ALL THE WAY up when testing. 2) run the tops first, then slowly turn the sub up until it fills out the bottom end, right to the point before it begins to play the same bass as the 12"'s. 3) Allow for a break-in period by playing your initial practice set at lower levels to give the speakers a chance to get going for the task. [SET UP NOTES] If you are using one sub with two separate speakers - simply run the left and right XLR out of your controller into the subs left and right Input/Thru and then run the left OUT to your left Top and the right OUT to your right Top. Nice and simple. For best sound, place the sub somewhere between the 2 speakers. If you are running 2 subs - run the left XLR cable from your Controller to the left sub Input/THRU and then run from the left OUT to your left Top. Run the right XLR cable from your Controller to the right sub Input/THRU and then run from the right OUT to your right Top. I know this seems like it shouldn't work, however, subs can work on a Mono channel, so having one signal to the sub is just fine. NOTE: if you run yours system like this, you will need to purchase On Stage SS7745 Adjustable Subwoofer Attachment or something similar so that you have one top over each sub, and then place the complete set to the left and right. All I can say is I love my subs and they sound incredible at an inside venue...

I saw this same amp in what looks to be the same box...with different names by at least 3 different companies. I am perty sure they come out of some Chinese factory/city. Then, the company here in the USA that puts their label on it, also selects a Speaker..as we have speakers available here that are competitive and it helps cut down on the shipping. I chose the Rockville company that handles this as they stated they had the heaviest weight speaker installed of the other companies. I bought two of these for a Bose like system on steroids..at 1/4 the cost. I bought 2 Galaxy 4 x 5" speakers for the line array style mid/high range as they cover up above what people can hear without a large fall in response up there. I also put a blocking network in them to block below 200 Hz from the Galaxys. So, I power them with a little one rack space amp of 200w per side...more than enough for my small to medium solo gigs, and am happy with the system I have put together. The rockville subs cut start cutting off frequency at about 175 hz and sound somewhat mute for frequency above what they are designed...such as kick bass and low bass. There is a control that adjusts this frequency sweep...I have it set on the highest level. These have also a volume control and a Nutrix input and output that takes a Balanced input or 1/4" line. I drive these full volume and they seem to take a large amount of low level signal to drive them. The box feels strong and they are a bit heavier than you expect...but that is good. The carpet cover appears of minimal thickness and quality from China, the corners have typical quality metal covers and the handles on each side are plastic and adequate. These also have pole holes ot the common size in the USA, I forget that dimension and if I remember...I am perty sure they are plastic and not metal...but could be wrong. All in all I like having been able to find a 10" little sub at this price to mate with my 10" 2 way Peaveys I some times use and also my new Galaxy 4 x 5" speakers that I also fly on top of these with poles. These subs are heavy enough to use a pole up to say 5' and put either of my mid/high sets of speakers on...as long as someone does not fall into them while intoxicated. The system has all the same perks of a Bose system that would range around 2 grand all for under 500. if you have a small amp in your rack to drive the mid/high speakers... I do it this way cause I play on the beach and like NOT to have amps or electronic that are exposed out in the high air to corrode from the Salt air... It also gives me flexibility to not use the subs in very quiet dinner settings. My friends have both over priced Bose and HK systems in the same design style of having no High end Horns that are harsh and cause feed back. I just dont like the sound of their little 2" multiple array speakers...so I went with the Galaxy with it's 5" array design and have a nice sounding system for cheap...I could have a quad surround sound system in each of the 4 corners of a performance room for the same price as the Bose system. Now I just have to have some custom bags made for the Galaxy mid/high speakers to keep them safe. If you want the maximum thump from 2 of these subs...place them side by side and make sure the phase shift switch...also on the back is set the same for each. That phase shift switch by the way compensates for the type of crossover on the top speakers. That top end crossover can make the top signal 90,180, or 360 degrees out of phase...as crossovers are named 1st order, 2nd order, 3 order and 4th order/360 degrees...the 360 is not so common but puts the tops completely out of phase with the bottom subs...so that is why subs have a phase switch and that is why your cords to them should be the same supplier or same polarity. You want the whole system pumping the same direction on hard hits of sound....and even small ones.

Finally tested the two 10” powered subs I received a couple days ago. I used XLR to 1/4 daisy chained ran in series to the second main speaker input on my Mackie 808S. I have had the Mackie head unit for about 18 years now and have taken really good care of it needless to say it’s still a hammer and still capable of pushing the 1600 watts with no problems at all. Don’t waste your time lining in to any type of auxiliary output go straight into the main or monitor speaker input. I usually run my mains and monitors in series so I have two extra speaker inputs that are available which I use the additional main to line the two 10” subs into. I mostly listen and play reggae, country, Hawaiian music so there’s a fair amount of bass in those genres. Tested these out with some Maoli music and let me tell you that these 10’s all though they be small they are mighty. Set the phase to normal dropped the low frequency knob down to 40 and could only manage to turn the volume knob about quarter way. My son and I were testing these out in the garage and at that volume my entire house was shaking. Good deep solid bass coming from both units along with one 12” JBL monitor that’s the same age as the Mackie board which still cranks too and is still in great condition. Looking forward to using these outdoors at gigs they will definitely add some nice lows to the already great sounding set up I have. I can only imagine the power and bass that the 12, 15 and 18 inch subs from this line can put out. Great purchase would’ve purchased 15” if they were available on Prime unfortunately not to Hawaii so I’ll settle for the 10’s which are just fine by me! Ok so I’ve had these for about 2 years now and I made some slight modifications to the two units I originally purchased. I ended buying 2 10” Rockville car audio subs with 160 oz magnets 1000 rms max 3500 watts on the cheap and replaced the original speakers that came with the unit. The little cabinet must weigh about 80 lbs now and the sound, the sound, it was already a beast of a little unit but I’ve turned them into absolute freaking monsters. The bass can get super deep super low and super clean turned up to about 3 o’clock a little past unity. They sound almost as good as 15’s and I’d honestly say give 12” subs a run for the money or might even be better. I’ve used these to run live sound for reggae bands and the musicians always can’t believe the sound coming from the two little subs. Only drawback is they get a little hot but I run vernado fans on the back of the h it and that helps a lot. All in all the compactness of the unit with the modifications, Unbelievable still stoked with the purchase.

I rarely leave reviews for products especially when so many people have said enough to have me sold. Let me tell you, for the money, quality, and performance, why did I wait so long to get one? As with anything, there are always more expensive and better performing products but this sub is banger! I bought the 18 inch and probably should have considered a 12 or 15 for my room because its loud! But I'll give you my reasons why I bought it. 1. Price - Most active subwoofers are expensive and some may agree to go with a passive and get an amp but thats more than this sub alone aready and it does it all for cheaper. 2. Features - Ahh yes, we all like features. I love my deep dubstep, trap, and other low hitting songs and this goes as low as 29Hz and it's adjustable! It as wheels, made it cake to roll to my room along with handles on 3 different sides. And has a pole extension for your PA's 3. Quality - Honestly, I would have paid more if there wasn't any better out there. The box and metal grate is solid. The carpet is thick. The wheels are smooth, not wobbly as what I would expect a "cheap" sub to be but man this thing is built nicely! How I connected? I have a pre-amp mixer and used just 1 XLR male to 1/4 inch and send it to my MONO out and I was good to go. Yes, it will take RCA's and any adaptive connection with it. So I bought it this because of the reasons above and I have needed bass for a loooong time but I've never been able to justify the price for some of the high end brands. I came across this one out of curiosity and a lot of the youtube videos, threads, etc. wasn't able to show me how well it performed for the price. Well I will tell you now, you can do all the research you want, but you will be surprise how much more this will give you than you would expect. For a house, it's a little much. For a mansion, still loud. Outdoor pool party, you will feel it in the water. This thing hits, quality lows, and I'm sure after break-in, I am in for a treat. From all if the reviews claiming it lasted more than 4 years with a good beating?! I would have enough money saved for bass for the whole neighborhood! If youre on a budget, and you need bass like youre at a EDM show in your room, this is it. I should probably turn it down, hard to write a review with the keyboard shaking.

I really like the sound and performance of the Rockville RBG18S\. Unfortunately, the condition in which these units arrived was unacceptable. I purchased the subwoofer from AudioSavings. The first unit arrived damaged. AudioSavings offered me a $20 refund to keep it, but I refused because I expected to receive a new, undamaged product. A replacement was sent, but unfortunately, the second subwoofer arrived damaged as well. AudioSavings then offered a $15 to keep the second damaged unit. The damage is especially concerning because it appears that the foot mounting screw is too long and has actually come through the plywood, cracking the cabinet. This is not simply a shipping issue—it raises a serious quality-control and assembly concern. So, I received two damaged subwoofers in a row, and neither should have passed inspection before being shipped. Offering a small discount does not solve the underlying problem when a customer paid for a new product in good condition. The subwoofer itself works great and sounds powerful, which makes this situation even more frustrating. I would have given this product a much better review if it had arrived properly assembled and undamaged. Rockville needs to address the assembly, screw length, quality control, and packaging. Customers should not have to choose between keeping a damaged product for a small discount or going through repeated replacements.

I treat it bad, I beat the snot out of it. It keeps on kicking. Loud, says down to 40hz, bet it is lower. Takes a few to break it in. I was disappointed to begin with. After it softened up, it gets down. Since I treat my stuff so badly, the crossover switch got banged up, so it was only getting like half the feed signal that equates to half as loud. If you moved the switch just a little bit, the other half of the signal would kick in.. then the thing would start pounding away, which, moved the switch back to only half feed. I stuck a toothpick in there, worked a little time, then some plastic, then eventually a screw. Thing has such a pound that nothing will stay in place for more than a few songs. I gave up and dug out the control board. I bridge soldered the switch contact for the frequency I wanted. That joker ain't slipping any more. Had it since 2017, it's now 2023. Thing is super heavy. I put some wheels on it on the back side. You know, dump it over where the speaker is pointed up and roll it away. That worked for like a second. The insane pounding shook those big casters apart. Like you would look back there and a wheel would be laying on the ground. Nut here, bolt over there. So i fixed and fixed and fixed, was a lost cause. Then after much mistreatment, the front grill started to rattle like crazy. Threw a few more screws in it and good to go... I can't speak highly enough about it.... one day I will donate this one and buy two more... one day

One of the cheapest 15 inch powered subwoofers I've seen. I have a pair of Alto 12 inch powered tops so I needed a sub to handle the signal below 100Hz. Let the Alto handle the highs and mid-bass while the Rockville RBG15S takes care of the lows. I was pleasantly surprised that it performed well. Not earth shattering performance but great nevertheless considering the price point. Glad I got the 15 instead of the 18 inch sub. The cabinet is big and heavy as it is. The fan is noisy, at least on mine. The output is not as loud as the more expensive subs but it mates and balances well with my tops. If this keeps on working for several years, I may have a great bargain in my hands. Only time will tell. "One Year Later" : I noticed two problems after using the sub for a year, playing mostly dance music and karaoke. Sometimes the sub will not respond. Playing with the switches at the back will bring it back or the occassional off/on will work. Secondly, the sub mated well with my tops only when I have the volume on the tops at 50% and the master volume controlled by my Allen & Heath mixer. Good for small gigs when you don't need to be "loud". When I play for more than 150 people in a larger venue, I had to turn up my tops to 80-90% volume, the sub's output is being overpowered. The sub cannot hang with the tops, volume wise. I think this sub will work well with low powered speakers (200 watts RMS or under). I tried my JBL LSR305 mixing monitor (low wattage 5 inch speaker) with the sub and it blended nicely. To sum it up, I would only recommend this subwoofer only if you have a pair of entry level speakers. If you have decent tops, stick to a higher SPL sub.

I like everything with this subwoofer Powerful,lightweight for mobile djing.highly recommend for mobile djing

Muy práctico. Lo ocupo con una bocina de 8 pulgadas y da un buen sonido, claro y fuerte.

This sub thumps pretty good, I use it for venues up to about 250 people. As I only have used it a couple times I can’t verify long term durability yet. I can say it seems well built and if it makes it to the summer I will get a second one. I also like that it has multiple options for the inputs.

El sonido es genial, es practica de llevar.

No fue lo que esperaba, un producto bastante caro, para el desempeño tan pobre que ofrece. No recomiendo este artículo.
