I've got a single 10W7 running off a JL 500/1. I'm in the process of buying gear for the next upgrade. I'll be running two 10" subs with 2 JL 1000/1's. I figured I'd buy another 10W7 since I already have one, but I've heard that the 10W6 is actually a better SQ sub than the 10W7. Is this true? Does the 10W6 hit as hard as the 10W7? Martin

I think they sound better, however, once we tune your car the w7's aren't likely to play much more than an octave before crossing so I wouldn't worry about it.

If the change saves you money I might consider it. I've not messed with the w6, but I didn't think they needed a grand per....

W6s do sound better than the W7s.

They need 1k per sub?

Do the W6's hit as hard as the W7's? Can the W6's handle 1000w like the W7's? I realize I'm contradicting myself a little bit, but I'm shooting for the very best SQ possible AND to hit as hard as possible. Maybe shut off one sub when competing in SQ and run both when I'm out and about..... Both of your opinions on this mean a lot to me. Martin

I guess I'm willing to give up a little SQ on the low end to be able to hit harder.

I wouldn't put a 1000/1 on either a 10W7 or a 10W6v2. No, the W6s aren't going to be as loudas the W7s.

Thanks for the quick reply Winslow. I've heard quite a few times that the people that win in the SQ comps. generally have AT LEAST 1000 watts to their 10" subs.I'm not talking about turning the gains on the amps all the way up or sending 20 - 125 Hz to the subs. I'll be running 3-ways up front (with an xtra tweet on the A pillar)including 8" Dynaudio midbass drivers in the doors. I'm guessing (you tell me)that my subs will be playing from 50 or 60 Hz down.Do you think I'll trash the 10W7's by putting 1000W on 'em? Martin

You don't need to worry about having two subs running during comps, nor about powering the heck out of them. They will be attenuated to be proper in the spectrum, we will try to have them play from 40hz down.

There is an output and sound difference between the two, you will have to decide which you want. I would personally go to a store and listen to the two of them before making up my mind.

^^^I second what he said!! W6's are much more efficient than the W7's too.

If the 10W6's are more efficient wouldn't they hit harder? Martin

Don't worry about your subs, your front stage will handle enough to keep the subs to a minimal factor. Figure out which is the cheapest way and go with that.


"Hitting hard" is subjective and will depend on a few different factors. Just drop those terms from your vocabulary [Wink]

OK J.D. I got it - thanks. Martin
P.S. I spoke to Wayne yesterday about moving ahead with the front stage install. One idea he had regarding the trunk was to build a ported enclosure for the 10W7 I already have.He said he just did one(10W7 w/ 500/1) in a Beemer that he thought turned out very well. What are your thoughts? What freq. do you think it should be tuned to if I go that route? How much SQ would I lose? What would be gained? I really don't know s**t about ported enclosures.

Yes Wayne Mckenzie....

You could port it, just tune low, I would go 20-25...Wayne will know what to do. Here is where you will have to make a decision though, if you want it to be loud you will need to tune a bit higher, 33 hz or so, but that is going to give you a big hump around 40hz which is not ideal for SQ, and the way to deal with it is not ideal either. Personally, I would tune it low, get less hump and have a flatter response in the subbass area.

You will sacrafice some output, a ported box gives you more output, but don't do things halfway, you are building a nice SQ system, don't screw it up with a heavy bottom end. If you don't like it, you can always change the bottom end, but I think you will be pleased with a real SQ setup, which IMO, always includes a very capable bottom end, but not exagerated.

I have a 2.5 cube box tuned to 20hz in my garage that I'm not using, I'm pretty sure that would be too big for the w7.

When did you talk to him? I just talked to him yesterday and meant to ask him what was up with your car.

He does good work. He did a teamate of mine, Will Reinholtz's VW.

I spoke to Wayne Mon AM.
It sounds like I should just leave the bottom end alone for the moment. Do you agree? I'll add another 10W7 and two 1000/1's 6-12 months down the road. At that point Wayne will start over as far as the trunk goes (false floor, amp racks, etc...). Martin

I've seen a number of cars he has done...he does some of the best work I have ever seen.

Will's car is sweet...though I think the kickpanel speaker placement isn't optimum, especially for the amount of work that went on there and his car needs to be right for 2 seat judging.
