Delivery to the novosibirsk region took a month, the fee itself in an antistatic bag. In size as matchbox is not large. Connected to the column 35 watts 6 ohms (so it is written on the muses. center) power supply 12 volts 4 amps, the sound can be said average expected better, there is no purity of sound all somehow mixed into porridge even the equalizer did not help.
