JL Audio is the choice if you're looking for clean, crisp and tight bass. This sub is very responsive. It handles a wide range of frequencies with ease. To get the most out of JL, simply follow the recommendations from JL. Build the box to spec and give it the power it calls for - don't over or under do it.

JL is the best and there is nothing more to be said.

I have an Atrend A152-12. For those of you who don't know; 12 inch dual downfire bedliner enclosure. Pretty much the best made for the silverado. Issues--.97 cubes per side. There is plenty of depth but good luck finding the correct sub. I WAS using some old school 12w6v1's with heavy polyfill. There was a noticeable bump at 100-60hz and then a sharp roll off. That said; those subs were perfect in the former 1.25 cube box. So I researched and researched; drove myself crazy looking at graphs in Win ISD pro with different TS parameters. So I decided I had to just do this locally so I could take it back. Well, the point is this sub is PERFECT for the box with medium polyfill. I am back in the high 130's SPL wise and clean as a baby's bottom! I mean CLEAN! Driving these with a JL Audio J2 500/1 and highs with a JL J2 320.4... Head piece is a stout but aging Alpine CDA-9885. Now to get rid of the craptastic MB Quart PVI216 components in favor of some Image Dynamics Ctx65cs's and the transformation will be complete!!! Oh yeah in short... You got this box? Buy these subs... Your research has already been completed.

I ordered these subs because JL audio has been one of the top brands for years. Trust me they didn't disappoint me one bit. I have a 1000watt Kenwood class d mono amp running 2 of these subs and they are capable of handling more. I wouldn't think twice i would buy them again there awesome subs.

I bought this 12" sub because I know JL Audio is always a top speaker in its class. I used to own a W6 many years ago and this speaker I think sounds better! Very impressed and overwhelmed that it sounds this good, shocked actually! Running 270 W RMS to it in a sealed 1.20 cuft box and it drops!!! But this sub is on spot! Not too over bearing but gives your incredible low sound and depth to your music.
