I'm having trouble driving my LSI 25's to high volumes.
Setup-- Rotel RMB 1095 amp. 200w/ch into 8 ohms, 330 into 4 ohms specs. Line level inputs into lsi subs, top binding posts dissconnected from botton posts.
Rotell 1066 preamp. I'm just listening to 2 channel cd's, i.e. JUST driving lsi25's (sub off etc). When I get to about 95db avg reading on my snd level meter, after about 10-15 minutes, the amp protection circuits kick in. (volume setting '72-75' on rotel 1066...max setting is '90').
Amp very hot. (I am going to have dealer check amp), but as everything works fine at lower levels .......It seems hard to believe that this 80 lb amp can't drive these speakers!!!!!!!!!!!!!!!!!! I even have a dedicated 20amp circuit for system.
My question is, although lsi 25's are rated at 4 ohms, in use, do they drop to significantly lower ohms???? Using polk audio speaker cable. Tried plain 10guage cable (runs 5 min longer), but still same problem.
Has anyone else had similiar problems? Measured db levels with what amps??????????? Thanks, Paul
