Read the description closely; these are not amplified monitor speakers, and it is arguable how "high powered" they are. These speakers require aseparate amplifier; you cannot just use the monitor output on your amplifier to power them. Misleading descriptions will get you every time...

Smooth sound, excellent value, great price, quick shipping. Have bought before and will buy again from this seller.

As others, I found that these speakers have "no" built in amplification. Have no idea why they are classified "Amplified Speaker." Finding a reasonable amplifier that matches the impedance is impossible, at least, so far or me. I'm sorry I didn't return them when I got them. Beware!!!!!
