Axiom Home Page Forums General Discussion Advice from Axiom Owners Sub advice : my head hurts

DSP in subs probably isn't going to be limiting performance, but stretching it beyond what an amp+driver would normally be able to do. So if the DSP is limiting the cone movement below 35 Hz, it's doing so because without it, the cone would be hitting the limits of travel at some playback levels. Those levels would not normally be reachable, with a less powerful amp. So what the DSP is doing is allowing a manufacturer to use raw power to get a sub to safely play lower than it normally could.
