best sub ever

This is such a quality product. The sub hits so hard and tight and very clean. I have never felt such a hit from a sub. I am pushing it with a ba gta 802. Bridged at 260 rms. It is a perfect match. For the price you will not find anything better! Thanks again Jeffrey you definatly know your stuff.

Best Sub

I bought 2 of these, originally I was going to go with JL since I have just come accustomed to buy, I am so glad I bought these. Jl's hit hard but are expensive and the build at least for the comparable model were week in jl. These puppies have some of the greatest cleanest sound I have ever heard. I have them in my dodge ram with limited space and they sound better than when I had 12's in my car, one of the best subs I have owned you can also change the impedance 2-4-or 8 ohm.

good sub overall

i have two of these in a small sealed box, and let me tell you this sub's sound quality is crazy. the bass is so clear and true-to-life it will blow away JL. this sub is easily comparable to the JL w3 except it sounds better and is a lot cheaper. boston acoustics have been the premier brand and fine tuning the features of these for a long time. and if you can get your hands on the G5 its even better.
