Dayton AudioTCP115-4 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.

Did a diy speaker works great for bass.

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.

Just an FYSA - these are not a drop-in replacement for JL/JT sound bars, I had to use an oscillating tool to trim the outer frame to fit.Once trimmed and installed, they sound great. The JL/JT sound bar mid-bass section is already ported, and these reach down fairly low for a 4" speaker, even without an amplifier. The sound is much better as a dedicated component/mid-bass driver than what you get with a coax speaker. If you don't want to cut up your sound bar to fit a larger diameter speaker, I'd recommend these.

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.

Excelente

Bottomed out really easily.

It works amazing and has very low bass for it's size
