Just got back from New Orleans and had the opportunity to listen to some live (way live, actually!!) Jazz. It started me wondering... What's the frequency range for the contrabass. I have an SVS PB12/ISD and I am wondering how much of this instruments' range is produced by the sub and how much by my mains? Mains are Pinnacle Pn8+. Sub is crossed over at 80hz. Receiver is the ubiquitous Pioneer 1014. I turned off my amp (front (L/R)speakers are powered by Adcom GFA 555) and listened to just the sub it seems like very little of the contrabass' FR is in the < 80hz range. Is this right?
