BIG speakers require BIG power
I originally had POLK Monitor 70IIs, driven by a beautiful sounding SONY STRDN1040 AND with a PS110 sub being . I then purchased these and was to can't run a musicians amp to power home speakers." When I'd ask "Why NOT?" i GOT A LOT OF VAUE non-PHYSICS ORIENTED RESPONSES OR NO RESPONSE AT ALL. wELL, THE SOUND WAS WONDERFUL. sO WONDERFUL THAT i BOUGHT another crown xls1502 AMP AND RAN THE AMPS IN BRIDGE MODE TO DELIVER A STAGGERING 2,100WATTS TO THE SPEAKERS!!!!. These speakers can handle 500 watts. But the 1050watts/channel(most would say overkill) made these speakers sing like no other!!. ALL my musician friends are in awe of my setup. It's not(primarily) that I can make my townhome development shake when I crank the volume....but the separation of sound and TIGHT bass to midrange is unparalleled. I would say the POLKS lack a bit upper register "sparkle" heard in speakers that have something driving the treble other than a standardand dated, neodynium magnet with a silk tweeter. Perhaps this is why Polk changed their tweeter material on their latest speaker lineup; getting up to 40khz instead of the 26khz from the rtia9s. i I am quite pleased with the speakers AND the "YOU CAN'T use that CROWN musicians amp to power home speakers." Class D CROWN XLS1502 amp has come of age. Many high end amp makers: Acoustic Research, Mark Levinson, use CLASS D technology quite effectively. These amps are LIGHTER, RUN COOLER, ARE WHISPER SILENT FOR ME and pack a PUN
Pros: Look like a piece of furniture. Sound is fantastic IF powered sufficiently. sEVEN DRIVERS CREATES A "WALL OF SOUND, Phil Specture would be envy.
Cons: Upper treble lacks a sparkle heard in other high end speakers. These things are HEAVY
