JL Audio used to be THE name in Subs in the 90's and early 2000's,.. and I used them about 10 years ago.. I decided to build a new complete system for my new 350z i acquired and install it all myself (a serious job, wow).. Anyhow,.. while some others on forums told me that "JL isn't what it used to be.. etc" -- I stuck to my guns and went with the JL Audio line of subs, in this case a 10" JL w0,..
I was NOT dissapointed. My goal was a good high sound quality system, it didn't have to have bass you could hear half a mile away, and I didn't want "boom boom boom" type of sound. I wanted tight , fast, bass response. I listen to mostly Rock/Alternative.
I put in some JBL MS62C components up front, and some MB Quart 1998 (German made) QM-160-KX 6.5 Coaxials in the back (wow, those older MB Quarts are miles above most speakers out there today),.. paired it with a Kenwood DDX470 and this JL 10" W0 from Crutchfield in a custom "stealth" .66 Cu.Ft. sealed box.
I'm running a PPI 900.5 - 5 Channel Amp, with 70watts RMS going to all four of the 6.5" and 1" tweeters , and 270watts going to this JL 10" W0v3-4.
All I can say is wow,.. and I'm so glad I stuck with my gut feeling,.. I knew JL Audio didn't somehow go to become "junk",.. and this thing puts out WAY more bass than I need, and it's clean, and "tight" bass. Don't misunderstand me, it will play Rap and "boom" just fine, but my design was for tight rock bass.
I highly, highly recommend this sub with 250-300watts RMS.
Pros: Best quality sub for price on the market.. at essentially $100,.. it's hard to beat. If you aren't familiar with sub brands, or just don't want to do all the research, just buy JL Audio of the appropriate size and model.. and you won't be dissapointed, it's that simple. Make sure you match the wattage RMS up properly.
Tight/Responsive Voice Coil (doesn't lag on quick rock, or double bass)..
Nothing classier than the JL Logo on the center of a Sub.. I'm sorry.
Cons: For a JL Audio sub? None. Literally none. The power range is perfect at 200-300watts RMS "preferred" (these days it's hard to find a sub amp output under 200-300watts. Thus it's quite efficient with the power it is given.
There isn't a con to this sub. If you are looking for shatter your windshield bass,.. Then just go up the JL Line to their W3-W7 models, and you likely want to go a bit larger 12-15" -- Be prepared to put much more amp on it though.
