Active speaker with a range of 35Hz to 20kHz
an LED indicating the ignition and a knob-20dB up to max
Neutrik connectors
for any use made of the mix

SOUNDS

No table provided on the spectrum of the speakers, but c is as neutral as speakers twice the price ateignant
nice stereo image j and for once not have the impression of having a subwoofer (I refer to alesis active)
a clear and precise on the entire spectrum with a good dynamic

OVERALL OPINION

I use them for 6 months more
what I love: the bass are not set too far forward, jy spend hours and even nights and j in the resort with a smile
I tested for 2 weeks and I've alesis also able to compare them with other models in stores and conclusion for me to have as good a sound with speakers of other he must pay the double price
I blame their c nya that there are no switches for setting the following environment so be careful with their investments
great value for money with the experience I do it again the same choice with eyes closed and ears mouths
