are your speakers capable of being wired in a bi-amp fashion. Specific
speakers under consideration are the M22 and M60's. Also is it correct that
the M80's are rated impedance of 4 ohms?
------------------------------------
Hello Tim;
The M60s may be bi-wired or set up in a kind of quasi-biamping fashion. The
M22s are not bi-ampable or bi-wireable.
I say "quasi-biamping" for the M60s, because true bi-amping involves an
external electronic crossover where you'd set the crossover slopes and
frequency for each section of the speaker system (woofer, midrange, and
tweeter).
You can try bi-amping the M60s if you like.
Frankly, in all my listening tests over the years, bi-amping does not bring
audible benefits to speakers used in domestic audio and home theater setups.
It has practical applications for professional high-volume sound
reinforcement in big theaters, rock concerts, and for some studio high-level
monitoring.
Yes, the M80's nominal impedance is 4 ohms and only a few AV receivers have
sufficiently robust amplifiers to drive them without current limiting,
shut-down or overheating. The AV receiver brands we recommend for the M80s
are Sherwood Newcastle (which we sell on-line), Denon, Rotel, NAD, B&K and
Harman/Kardon.
Power amplifiers are no problem driving the M80s. It's only some AV
receivers (Onkyo, Sony, Kenwood, some Yamaha, Pioneer,) that have problems
with the current draw of the 4-ohm M80s.
Kind Regards,
Alan
