Dayton Audio TCP115-4 4" Treated Paper Cone Midbass Woofer 4 Ohm

2004 LX470 rear door replacement speakers. Just the right size (4.5 inches outside diameter - an unusual size). I replaced the blown Mark Levinson amp with car amp that has Bluetooth so I needed 4 ohm speakers to replace the 8 ohm factory speakers. These fit great, no cutting required. I did need to drill 2 holes in the old speaker mount and add 2 screws. They sound much better than I expected for their size. I kept the old ML tweeters in place and wired them in also.

Very clear and full sounding speaker. Put it in a .20 cubic foot box with a 1” x 3 3/4” port and a cheap tweeter and you’ll be happy. Trust me. I used a cheap Bluetooth amp board 50 x 2 and it sounds wonderful. I built one speak and it fills my den very well. The first time I powered it up I thought I was also Bluetoothed to another speaker due to the bass. For the price you can’t go wrong.

Did a diy speaker works great for bass.

Bought this 4" driver for diy "boombox", istalled to eclosure with 2pcs 4" chinese passive radiators, they are very light. Im currently using zk21-tb - amp's sub out for driver, tested also with L/R - output. Sound quality is fine/good for the price. Driver can't play high volume with low keys, distortion appears very quickly. I think over all quality is great, will buy more later.

it was wrong for me. I returned it with no problems.

I bought this speaker for a project I was building, a little practice bass amp for my girlfriend, in the shape of a milk carton for fun. I used a different 4” midrange speaker facing out the front, and this woofer mounted in the bottom facing down, and it puts out a surprisingly strong WOMP for its size! Feels like a great quality speaker, I would definitely buy it again.

this is just a full range woofer with more excursion. do with that information what you please

Wow! 4" woofer! Ummm.. These little things are BEASTS!. They pound like 8" and they just deliver.. The excursion is amazing for their size. I took two older bookshelf speakers and made a Bluetooth speaker jam box with a cheap Amp and wow.. They go deep for the size and really fill up my entire kitchen with sound like full size speakers would... Highly recommend these little crazy incredible hulks! Over the last few days played anything from smooth jazz to Hard Rock to anything you throw at them and the price is so cheap! That's a rare find to have speakers this good for very little money.. Buy them.. You will NOT AT ALL be dissapointed.. Update.. They still are pounding like champs... I ordered two more and will continue to with Bluetooth speaker box projects.. I'm running them off a Bluetooth amplifier board that is rated at 120 watts x 2 but we all know in reality that those little Amp boards are a little hefty on the claim of actual rms power.. However, I get a good clean 60 to I'd say 80 watts per channel and they hang at the rated power.. Just a very well made inexpensive killer small subwoofer.. Don't be afraid because of the low price.. They rock..
