clipping

Rotel receiver may be too weak and B’s are definitely too heavy.

Remember amp must be heavier than speakers -- use scales to measure 😁

yes, just thought  a preliminary would start.  my new equipment is parasound a21 and adcom 915 preamp, what a difference but still clipping at 80 decibels

The A21 should handle 80db easily with those speakers. Can you describe what you mean by clipping? It might also be helpful to know something about your source components. 

over 80 it cuts out for a second, component is rotel 1072 cd player  i have 16 ga. wire with banana clips and other wire is capable monster cable supplied when i bought the system

How are you measuring 80 ?? Is that the setting on the amp or a measurement of the audio level at yoru seat?
