Alienvibes W601 2.2 speakers from ineo technologies absolutely adhere to audiophile starting points on how to build a good speaker set. Right off the bat, the Alienvibes W601 features all wooden enclosures with piano black plastic trim, satellites with 2 x 3” midrange and 1” tweeter, plus a pair of 5.25” drivers in a vented enclosure handling the lows. The amp built into the sub enclosure pumps out 15w RMS x 2 to the satellites and 50w RMS mono to the subs with an active crossover. The face of the sub enclosure has an easy to use interface for vol/bass/treble/input/mute as well as USB and SD card inputs. Simply insert a USB or SD card with music files and the W601 can play them back with full control plus an EQ with eight factory tuned presets. Dual inputs for RCA and 3.5mm allow for multiple sources to be used, making the W601 a great audio piece for an entertainment center.
