JL8W7 vs. 12W3v2

I'm looking to upgrade my system and maybe saving some space at the same time. What would be the noticable diffrences in these two subs? It's for an 03 Altima trunk w/MTX 895 amp(320X1 @2ohms). Thanks.

I have the a 12W3v2 and it is pretty damn nice...plays loud and nicely even in a ported box. But i would bet money the 8 W7 sounds nicer. Ive heard a 10W7 and wow was surpised by its performance. I think either would be a good choice...Go to your local dealer and hear for yourself since you will ultimately make the choice. I belive the 8w7 and 12w3v2 are both rated at max 300wrms. But with JL 's underrating they will easily handle ov er 300wrms. I currently pouring 500WRMS into my w3v2.

I'm also looking into possibly buying an 8w7. Mostly just for the shock factor. I figure if you build the right box, and give it a good supply of power, you could make it loud as hell. Then when people ask what you've got, you can just tell them you've got a single 8".

W7 or no, replacing a 12 with an 8 is retarded.

Yes, it'd be a wee bit cleaner.  It will also lack any real low-end and be an 8.  Come on.

Sedate, how does your W6 sound in comparison to a W7

The only W7 I've ever heard was in a competition ready SUV... the thing had like a $5000 signal processor, Zapco amps, MBQuart QSD highs, and like 5 cases of Dynamat Extreme.

I mean, it wasn't really played loud but the system sounded, obviously, really good. The bass was.. well.. incredible. Deep, clean... I mean. Here's the thing, with Zapco amps, and 5 cases of Dynamat, and in the fact that the sub was playing directly into the listening environment pretty much lead me to say that I can't provide a comparison. The system above isn't really indicitive of a 'real' system.

Overall, I've had the W6 for almost a year and the jury is still out... its very clean and articulate.. but.. I've had pretty poor luck building boxes for it... I've gone through at least a half-dozen and I've really never been very satisfied.. always clean.. just not all that loud. It doesn't really keep up with my highs the way I'd like.

I'd trade it for a pair of Infinity Perfect 12's in a half-a-second.

I had the W3v2 in a ported box and I was happy with it but like I said I'd like to change up my system a bit and I'm considering the 8W7 based on my current amp and like boardinbum said, the shock factor.

Also consider impedience. The 8" W7 is only available in a single 3 Ohm voice coil. If your amp is a non 2 ohm stable A/B amp it will shut down at this rating. On the other hand if you have a non JL slash,  D class amp you will lose about 25% of the amps power. JL rated these at 3 Ohms to encourage use of their "Slash" series amps where impedience does no matter.

Well, there goes that idea. Thanks for the info tcss, I didn't even realize that. Any one got any ideas for a sub now? Still looking for maybe and 8" around the same power requirements at 2ohms.

I've done some excellant sounding systems with multiple 8" JL W3V2 drivers and since they are rated at dual 2 , 4 and 6 ohm coils you should get your 2 ohm load no sweat. Also you can build them down to 3 cu ft, much smaller than 8" W7. Another alternative 10" W6V2. We are just ready to fire up our new store demo car ( 2005 Acura RSX ) it has two of these in a fiberglass 1.3 cu ft encloser and I expect it to be very impressive.

How about (2) 8W3v2's wired down to 2ohms @125w a piece backed by a 320w amp? Would it be better to run two of these as oppsed to like a RF P3 8"? Thanks for your help tcss.

I like three personally but two should do fine unless you are going for BIG volume. Also these drivers tend to like quite a bit of batting ( 2" all the way around ) when they are mounted in small sealed enclosures.
