What subs are comparible to W7's?

[vasilios 10+ year member]

I run a hifonics bx1500d on mine at 1 ohm.

It is loud and reaches its limits with that.

XXX is 1600 watts rms

refer to Tirefryr's post about upgrading from the w7 to a new generation mag. said he wont go back to the w7.

ive owned both gen, mags but no w7. i can say the mag sounds awesome though for sure.

have fun finding them and more power than a w7. Probably 1000-1500 is sufficient. Anyway, if I wanted 4 subs that are equivalent to a w7, this would be my choice.

They come in 4 packs at 150 a driver if bought in that quantity. It uses the same tech xbl^2 that you get from the xxx and cost less than you'd pay for a used xxx. Excursion is basically the same and they don't require nearly as much power. I graphed a 12w7 and a shiva x in the box you described using winisd. the w7 had slight edge below 40hz, the shiva did better from 40+. All in all pretty identical, better group delay with the shivas though, so sq might be better. This is mainly because the shivas want a bigger box, I'd stuff it with polyfll, odds are that'd fix it.

never heard of these, are they actually any good???

how much power am i gonna need to run those, and are the 12's?

Very good, designed by the guy who built the original xbl^2 drivers. Dan wiggins, he owned the company that RE got the tech to build the original 05 XXX's from. Frankly, I'd take a shiva over just about anything if I had the room and needed a new sub. Can't beat the displacment for the price and I can't imagine the engineering to be anything less than solid. The new mags aren't out yet.

 

[BassBallin]

when do the new mags come out yet, and are there any specs or pics of them?

also what is the si mag website so i can look at the current ones.

 

[BassBallin]

these si mags definatly got my attention i was reading some stuff and people were doing 152.xx on a TL with 2 of them on 3000 watts

if that is the case what is the potential for 4 of them off 6000 watts???

 

[BassBallin]

uh oh do they even make si mags in 12 inch subs or only 15's???

http://www.stereointegrity.com/mag.php There you go, but beware that those are no longer in production and the new ones are at least 2 or 3 months from production.

At least, to be honest from what I have heard from Nick and with the time it takes to tool something and start manufacturing you may not see these before spring next year.

well **** that then, by that time i will have the money for w7's

i dunno maybe ill give the fi q's a try or try and locate some 05 xxx's

Actually the sub in your sig stomps a W7, but he was looking for 4 12" subs because he already has the boxes.

what is the bp option??? what does it do???

This new option adds a machined aluminum compression plug to the pole which helps channel all of the air under the dustcap around the coil for better cooling. To aid with this increased airflow we also add 6 axial cooling channels in the top plate. Along with increased thermal capacity comes the addition of an extra spider and a changed spider pack.All of these new features increase power handling from 200-500 Watts depending on the application.

I asked him that in an email.
