I have two (single 4 ohm) 15" MTX Thunder 9500 series subwoofers. First of all they are just flat out insane! I have each of them in their own ported box and with 600 watts into each and they are moving around 1-1.5" inches out of the 4" that they do move. They are the deepest and loudest subs I have ever heard. They are almost as clean as eclipse aluminum subs, but with the thump of a serious spl woofer. I am in awe from this sub. Each sub handles 1000 watts rms and 2000 watts max. These statistics are way underrated. Next week I am going to be giving each between 1200 and 1600 watts rms each. I haven't had them metered yet because I want to wait until I get the both of my Thunder 1501D amplifiers hooked up. The second reason is that I am going to be getting the dual 4 ohm version of these subs. After I put the new subs in and get the amps hooked up I will have it metered and I will be sure to post what the system hits. If you have any questions in particular feel free to ask.
