JBL W12GTi MkII

wow, what can you say. for starters this sub is rated at 700Watts RMS, but it is quite capable of handling much more! i did contact jbl's tech support and engineering department when i hooked this sub up to my planet audio BB2400.1, i told them that i was sending ~1200 watts to this sub. there response was something along the lines of "oh yeah i know it can handle power." it does get hot but then again this was a subwoofer engineered to take heat. simply put, this is an amazing product. i would recommend this to anyone who is looking for loads of bass in a relatively small package ( it needs 11" mounting depth!). i have had it in ported and sealed boxes built to spec and either way you will be impressed. i hope this review helps and clears up any confusion!

I got two gti's when they first came out and got sick of them blowing out. Then i got 2 L7 12" kickers. Not only have they out lived the gti with same power output but they bank way harder way longer, sound better, etc. Buy this speaker at your own risk and if you do purchase a jbl amp. They last longer and are under rated. I did have those for a while and were cheaper and put out for a long time before they gave up on me. Good luck use your head and go with another brand. Kicker is the way to go there is a reason why they are the hottest seller QUALITY and the higher up you go the biger bang you are going to get. L3, L5, L7, SOLO X, also CVX is sweet!

I have two of these breathtaking beasts and they are simply flawless JBL doesn't lie when they say the ultimate woofer, sure there are subs out there that can take 3500 rms but this gti doesn't slack when I first got this I didn't have the 2nd one so I hooked it up to my bpx 2200.1 all by it's self and gave it 2200 rms in this small little sealed box I had laying around and it took it for a good half hour, I wouldn't do it often but it will take a lot more than 700 if you have good voltage and no distortion I've got them each in a ported 2.2 cu box now and they are just amazing. Extremely loud super clean really low deep violent brutal bass!!!!

I owned a single JBL GTi for little over a year when i was first starting out. I had it hooked up to a rockford fosgate 800.1 amp, little did i know this subwoofer could handle so much more power. I finally upgraded to a audiopipe ap3000.1 class d amplifier and wow can this subwoofer handle power!! I've been running about 1200 rms though it for a few months, never any burning of the voicecoils or anything, always a very clean sounding sub. Everytime a new person has entered my ride and heard my system they see my massive amp and always ask how many 15's you got back there? You just have to laugh. I'm upgrading to about 6 of these bad boys with 3 of these audiopipe 3000.1 amps. You will probably hear me from where you live. JBL FTW!!!!!

I upgraded from a 10" Alpine Type X in a ported enclosure to this MkII in a ported, spec'd enclosure powered by an MRP-M1000. I have the gain set about 60% and the low pass filter set at 80Hz. I usually listen to country, rock, and rap at moderate levels, but this sub sounds great even when I want to rage.

Blends beautifully with the front stage, and the response in the ported enclosure seems fairly flat (good thing) and surprisingly quick. Definitely a huge upgrade from my Type X. Remains undistorted even at very loud levels.
