Plutos with external power amps?

fxs · 20th February 2011, 02:06 AM

Hi all. Im thinking about building the Pluto Linkwitz loudspeakers

. As i have a nice receiver (a harman kardon with 30w/channel), i was to build only the active crossover, and use the amplifers from the receiver.

Seeing the driver´s specs, their sensitiviyt is about 84dB/watt, and given Linkwitz says the power amps are an integral part of the design(50w for the tweeter, and two bridged 50w for the woofer), not sure if the amps would be underpowered for the speakers, and not listening the full potential of plutos

For those using external amps(especially with less power than specified), how has been your experience? Could be my amps underpowered for driving the Plutos? fwiw, the harman amps are known for being high current, and realistic about the rated power..

I use a vintage 80 WPC Sansui receiver which easily power my Poor Plumber's Plutos at 80 dB/W efficiency and are passively crossed over.
