I have about decided on going with 2 W7 12s. My question is that they have single 3 ohm voice coils, what are the wiring options for this sub? Like what are the ohm loads when in series, parallel or combination series and parallel? I havent found any charts yet that show what to do. Hazard maybe you can help me out on this?

Thanks,

Blah I jsut wrote a whole thing and the website bombed. Sure is acting screwy. Anyway, sumary......

Series 6 ohm, parallel 1.5 roughly.

If you're looking for maximum sound quality then use a 2 channel amp with lots of power at 4 ohms. If you just want insane bass, a bridged parallel config should work on any GOOD amp rated at 2ohm bridged. I would imagine this would sound pretty darn good too.

 

1.5 ohms parallel - 6 ohms series.


It may be risky to run a 4ohm amp at 3 ohms. Although, in a sealed box it should be fien just make sure its of 'decent' quality.

On a side not I have two 10w7s powered by two Zapco C2k 6.0s. http://www.sounddomain.com/member_pa...=287790&page=3

 

Hey HAZARD.. did you just buy the Q-logic kickpanels and enclose the back of them? I see you did some fiberglass work for the kicks but I couldn't exactly tell what all you did.

Thanks. I'm definitely going to do kickpanel installs soon but not so sure about the fiberglass stuff.. still researching.

 

Thanks guys! One last question, Do you wire it the same way as you would 2 voice coils? I figure it is but i wanna make sure. My freind heard one W7 10 in an Acura RSX and he said it was loud like a 12 and sounded so much cleaner and clearer than any other sub he had ever heard. Thats kinda why Ive been thinkin about goin with these. Think its a good choice? I was thinking either 2 12 W7s or 3 10W7s but it think i could do the 12s fo a little bit less money.

Thanks,

Keep in mind that the installation and even the vehicle play a big part in how the sub performs.

 

True, and old friend and I used to swap/share equipment between vehicles. With the 2 15's in his Grand Am it never did sound quite the same as it did in my LeSabre, but his would rumble the street for 5 blocks where mine was semi tame at 1 block. I prefered the sound staying in the car.

 

That's why JL used 3 ohm coils...you almost have to use their damned amps too, cause they make the same power wether it be 1.5 ohm, 2, or 3.

...but if you have the money to WASTE on a W7, you can waste the same on one of their amps.

I wouldn't really call buying their amps or W7's a waste. They are both SOME of the best equipment out there.

 

I didn't mean their equipment was a waste...just that there is a LOT better out there for a LOT less $$$. If you have the sub, you can buy the amp to match it. To each his own.

Please do tell...What out there is SO FAR SUPERIOR FOR SO MUCH LESS?


As far as my kicks go...those pictures were of me beginning to build my kicks. I had Q-Forms in there before because I didnt want to deal with the hassle of building my own, and for the money they are worth it, but in the passanger side the soundstage is a little low. If you get the Q-forms then I just say glass the back and you should be good to go.

PS sry for the delay, just been really busy around here.

 

Well, I was just trying to be funny in my first post, so I don't want to start a war. Just, IMO..for SPL: DD 9900's, 9500's. For SQL/SQ: DD 3500's, 9500's, or the RE XXX.

The 9900's are probably close to the same price as the W7's though...oh yeah, and I guess the new MTX T9500's have been labeled the "W7 Killer".

No doubt, the W7 is a nice, well made woofer...but for the price...??? If they are anything like the W3v2 or W6v2's they don't have a very long suspension life either.

Probably a more fair comparison would be the RE XXX.

Well to start off the w7 isn’t an SPL woofer. Also, I wouldn’t even say they are close to the 9900 series subs in price, where can I get a 9900 series sub for $350, $450 or even $550 for that matter. I wouldn't put the 9500 anywhere near the w7 in terms of SQ either, I think the only DD sub that closes even relates to the w7 would be the 9100 series subs. Yes the DD would most likely slaughter the w7s in terms of SPL in the proper setups, but in terms of SQ I don’t think any of the DD line up can really hang with them (with maybe the exception of the 9100...don’t know a whole lot about them).

So I don’t think the w7 compared to a 9500 is even really a comparison, they are two pretty different subwoofers. I think a better comparison would be the Elemental Designs As, but these subs really did not impress me too much either. They sounded pretty good and come really close to the w7s, but I was not impressed with the output of them. Also, you get what you pay for...these subs (notably the 15A) have been known to have a few problems/bugs/design flaws or whatever you want to call them. Another good comparison would have been the Adire Audio Brahma yet, the prices aren't too much different here (well for the smaller sizes they aren't) but with this comes its problems too...can you say tinsel slap? Then there is the RE XXX, which I heard for the first time about a month ago...it was in a fairly large ported box and had a lot of output but here again I don’t think the SQ will match up to it. Yet, there is the IDMAX, great SQ, but lacks the output...Now there is a lesser known woofer made by Illusion Audio called the ND series, it is known to have EXCELENT SQ, but the output would be no where near the output of the w7, the same would probably be the case for the lambda.

So yes there are woofers that compare the w7, but you have to give and take for what you want. Your closest match would the Brahma (at least in my book)...

I also wouldn't get my hopes up on the new MTX sub...their comparisons between the w7s have some seriously faults.

Say all you want...say I’m hyping it up because I some, but to date I have NOT heard any other woofer that has made me even come close to thinking about getting rid of the w7s. But, once that day comes that I do hear a woofer that sounds better then the w7s with comparable output (or more) then the w7 will be out of the door ASAP(because I am in search of the best woofer in terms of SQ with some nice output...SQ is 100% my goal...Im not willing to give it up for output). - It just comes down to what YOU the user wants- If you want SPL then the w7 probably isn’t the best for you, it you want pure SQ then there may be better woofers out there, but the w7 may still compete in this category, but if you want a driver with the best SQ and the most output (with out doing a trade off of either) then the w7 is pretty much the top dog out there. Again argue it all you want, but talk to people who have owned them, tested them, or even other smaller companies who try to compete with them (Adire, Elemental, RE, ect...) even they cant deny its one of the top woofers out there.

 

Yeah, I gave too many options without better explanation...should have stuck with the more direct comparison. I thought W7's ran $800 - $1,000? Did they finally drop in price? I have a hard time believing a 2003 RE driver of any series with an XBL2 motor structure wouldn't sound better at high volume than a W7, but I haven't had the opportunity to compare for myself yet. Also, the DD 9500's weren't designed as SPL subs, but studio drivers and AMC theater use I believe, in OEM form. They are just so overbuilt they can take the power and abuse to break world records. I couldn't ask for better SQ out of mine, even in my somewhat large ported box, but I am downfiring. What sold me is the fact that for $120 DD can take my motor structure and rebuild, replace, upgrade, or even go from a 10" to a 15" driver if my needs ever change. We all have our reasons for choosing a specific driver, that's why there are so many to choose from. It would suck if we all had to run 10W0's in a small sealed box with a 100W Kenwood amp. Wanna talk amps? I need an 1,800 - 2,000W monoblock that's as reliable, efficient, and cool running as the Cadence A7+hc. Was hoping to check out their new RS line, but no one has much experience with them yet that I can tell.

BTW, check out the new 9100's if you get a chance, I'm curious myself. All "we" have are 2000's, 3500's, and 9500's systems. The new 9112 is only $440.
