Very nice!

Crisp, nice, loud, solid bass. Got this for my 88 bmw e30 to pump through the ski pass from the trunk into the cabin and it is perfect. Helps provide excellent sound with solid bass. Definitely would recommend!

Great subwoofer at good price

Few subwoofers sound good in infinite baffle, this is one of the few. I have these in a pair in two different cars and they sound great in both. They can get a little boomy in this application at low frequencies, but it's mostly tuneable.

Only issue is that the cone is quite beefy which is a good thing, but required I make a custom spacer to fit a standard enclosure size.

Great

Used to replace the stock sub in my 01 Tahoe. Fits perfect. I'm not running it off the stock amp, I'm running off a separate 300 RMS at 2 ohms amp and it sounds great (today anyway). 8.375 outer ring diameter fit great because the factory enclosure mounts the sub inside a 8.375 frame.
