[QUOTE="Buck, post: 8762879, member: 591582"] I'm sure every amp should be judged by it's individual performance. I just can't help but notice that on the more extreme builds I do or people I talk to, that the full-bridge amps do not perform like the seemingly half-bridge amps do. I'm referring to musical boxes and high SPL at very low frequency playing boxes. I am not including higher bass SPL boxes in that amp comparison. Since the wavelength of low notes is so long, the sub tries to push in and out for a longer duration. Each + and - peak lasts for longer, so to speak. So, the amp's ability to control the sub's cone movement during those potentially high xmax/long polarity duration situations can very greatly affect the overall sound. There's a difference between amps pushing/pulling a woofer cone vs "throwing" the woofer cone; the actual sound wave being produced by the sub can be distorted if the amp loses control of the woofer, say at a certain amount of woofer xmax.
