W12GTi MkII est évalué 4.5 de 5 de 8.
Rated 5 de 5 de par Absolutely insane... I did not know one could experience too much bass. How sadly mistaken, I was. I wired it up by the 3 ohm configuration through a 2 cubic-yard labyrinth box, and a 3k watt amp (1500 rms)... I could not find enough settings to drop to minimum and turn off for my ears to stop bleeding. Rewired down to 12 ohms and now its the purest, delicious bass you can imagine. If i ever need to blow the clothing off an entire stadium of people, i'll go back to 3 ohms. Feels good knowing i've got that much headroom, actually. And with the lower-power configuration, everything stays blissfully cool with no interruption to performance or my car's lights (yes, the 3 ohm config dimmed my lights with the lower bass. lol.). Buy it. Buy it now.

Rated 5 de 5 de par AAA+ I have been building car audio sub woofer enclosures since 1985 and in that time I have had the chance to play with almost every car audio sub ever made. These Wgti subs are still by far my favorite sound quality woofer , I listen to my music loud push my system hard daily for 1 to 2 hours at a time and these things never miss a beat or mud a single note, the note separation and articulation of this woofer is second to none , the guitar strings and drums SNAP like they each have their own source ..... if these woofers don't drop your jaw they were installed wrong ( very wrong ) I am running two 12" powered by a Crown BPX 2200.1 and I have 2 enclosures that I am bouncing back and forth with 4.0cf3 tuned at 28hz and 4.0cf3 tuned at 30hz and I think I'll be sticking with the 28hz enclosure once I add midbass it's really too bad they are now a discontinued product , I'v enjoyed working with them not shure what I'll do once I wear these ones out though everything else is a downgrade IMO

Rated 5 de 5 de par Ultimate Sub Having played around with many subs from different brands(many high end)this GTi sub is by far the most musical subwoofer I have ever used.Stunning attack,phenomenal low end without any hints of struggle.Powering this sub using JBL Crown amps puts it on a whole different level.If you are looking for the ultimate sound quality or ground shaking SPL subwoofer,I'd highly recommend the GTi series of subs.

Rated 5 de 5 de par I believe these subs are the best on the market I changed my systems from Polk which I loved and thought I would try JBL. I believe I have falling in love all over again because I am totally blown away by the clarity of my system which consist of P660c, gto329, p662, p963, 3each w12gti wkii subs, gto1001ez sub amp and gto 840ez 4 channel amp AWESOME!"

I have a pair of these is is worth it to run 8 gauge wire on the terminaks

Posée par: Jason123
The W12GTi MkII is a 700W RMS and normally, 14-16 gauge wires is more than enough for most installations.

How many cubic feet should an enclosure be for 2 of these

Posée par: Cade
Assuming you are building a sealed enclosure, 1 cubic foot is recommended for 1 speaker. If you are running 2 speakers in the same box, all you have to do is double the space, making it 2 cubic feet.

Is a sealed enclosure recommended over a vented one? If so how much airspace should an enclosure of each type allow for this woofer?

Posée par: TyLane14
Thank you for your question, this would be a user specific question.. depending on the genre or music you are playing can vary on different boxes and types.. ex.. if you listen to hip hop, heavy bass you would want a vented speaker box.. for Jazz and easy listening sealed box would be good for bass to roll out.
