First of all: The boxing need a while to play along, so who thinks that one could start immediately, I disappoint reluctant. The woofers have very good sound pressure and may well bring the furniture to wobble. The middle and tweeter sound ranging up ca.90dB very pleasant, but can then clink given the amplifier already. The sound is neither too hot nor too cold, thus ensuring a very satisfactory musical experience. I run the speakers to a stereo amplifier with 150 watts RMS output power and am therefore not affected by a digital processing from the amplifier which greatly affects the sound, especially in the noisy area. Last but not least is still to say who recorded with less RMS power (amplifier) boxes with more rated power, to should about clinking not complain because the frequencies are no longer sinusoidal (ie original), special taking place in the midrange and there are then all midrange with too much power totally overwhelmed, because the amplifier then the frequencies, the volume or bass sake, pulls in the midrange. Therefore pays when buying on the power of the amplifier!
