How about using this woofer with JBL driver, anyone tested ?

What frequency range are you after?

It will go lower than a 2235 in a smaller enclosure with about the same top end (~>1,000 Hz) and maintain as good or better overall linearity across its bandwidth. But they take a ton of power. I use four of the 10" versions in 2-ways with 2425s/butt cheeks for my surrounds and the 15" shares my center channel cabinet (internally separated) which uses a 2235/2420/2405.

I am afraid it is the wrong driver...

There must be a reason that it's a car audio woofer, not home audio. I think that it's cone is too heavy to sound decent above 150-200Hz.

Funny that the FS of the W15GTIMkII is actually higher than the 2235H - 25.2Hz vs 20Hz also the W15's cone is much heavier.

I found this on a car audio forum:

No need to speculate. The frequency responses of the two have been compared (in the same cabinet) and the results posted here in the past. The Moderator could bring it up. The W15GTI was more linear across the band and easily went over 1kHz. I cross my four W10GTis/2425s over at 800 Hz just to match the front channels.

A w10gti isn't a w15gti

[Voice]

I was thinking on cloning 4430 (size and look) using w15gti mk2 for the bass and Jbl driver for upper range. Bass should go up to 750-1khz.
Reason for W15Gti mk2 is the price and its availability. Not sure what Jbl driver to use, or maybe its just a bad idea.

[martin2395]

Well...a new W15GTI here costs 500-700 euro, you can buy a pair of blown JBL 2225's or just the baskets for 50-75 and recone them both with genuine kits for less than 700.

Secondhand i can get W15GTI MK2 for about 400-450euros/pair and 2225s are hard to find.

If anyone can get clean sound above 200Hz from a W15GTi, please chime in...

The Vertec 4881 that uses a 2256G (very, very similar to the W15GTi) is spec'd at 22Hz-125Hz within 6db (+ or - 3db), which is hardly linear. That W15GTi is a great subwoofer and shall be used as such. Certainly not a wide range transducer. It is not a 2235. ;-)

Have you tested it ?

Have you tested it ?

I haven't tried going to the moon on a moped, but I can assure you it won't work But hey, I suggest you buy a pair of W15GTi and report.

I am not going to buy them just for testing, thats the reason im asking.
