That seems unlikely... They are 89 db efficient with 8 ohm impeadance, and unless they drop below 2 ohms or something when driven you should not have much issue.. Sounds like either the speakers are blown and show distress only at a certain volume, or the amp is having issue, or your preamp signal is bad coming in and maybe shows it at a certain gain.. Bad volume pot or something? I don't know much about the amp or speakers you have but from the specs it would seem they work fine to realitivley loud output, and would probably shut down the amp into a thermal protection or something well before it would clip to easy.
Current vs. Watts??? Need clarification.
I've got a Rotel RB 1070 PA (about 125 watts) driving Spendor S8 speakers and I can't escape the feeling that this amp doesn't deliver enough power to drive these speakers. I'm getting clipping at pretty moderate volumes - say 1/3 on the volume knob. I've heard that this may have to do with the level of curreent actually being delivered to the speakers, as opposed to the amp's stated wattage output. I have read that the S8s like a lot of power but I would have thought 125 watts sufficient to drive a 2-way Is my amp just too small? Anyone have any thoughts on this?
