Would this amp work to power an SVS 20-39 CS?

    I've decided for now to use an old two channel (150 watt per channel) amp that I had to power a 20-39 once I made my purchase.
    In looking at the specs the other day for the amp, I noticed that it's frequency response was only 40Hz-20KHz!
    Will this not give me what I need in the lower frequency range (below 40Hz)?
    Thanks.

    Well, one way to find out is to get a CD with a frequency sweep starting at or below 20Hz. I've got VE (which doesn't [​IMG]), but doesn't Avia have a sweep? I did just buy a test CD from Stryke Audio that has 30-second intervals from 10Hz up to 20KHz. That way you'll know if your amp is passing the signal. Hope it is [​IMG].

    P.S. FWIW, I had to buy a small amp from RatShack (using it, basically, as a line level to speaker level converter for my sub amp, which only has speaker level inputs) that is rated 20-20K, and with the Stryke test CD, my sub is getting the signals below 20Hz. I can feel 10, 12.5, et cetera. The 15Hz signal shakes the crap out of my walls [​IMG].

    Troy,

    It's likely that your amp is only "rated" at 40-20K. That doesn't mean it can't do it. You can always try. Testing it with a bass CD as suggested above is a good idea.

    Troy,

    Sorry for the late feedback. E-mail is best when you really need a response.

    I'd guess that amp is actually capable of producing power well below 40Hz but it's hard to say for sure. I can't imagine one that has a subsonic filter set so high.

    As with many things there is one certain way to find out.
