This is a really remarkable cabinet. The most interesting cab we've seen in a while. The 2x12" + 2x10" arrangement proves to be perfect with focused lows, detailed mids and a surprisingly flexible High End detail. You can use all drivers at the same time (4 Ohm) or chose the pair of speakers you want to work (in that case impedance is 8 Ohm). This means you can tune your cab according to the sound of the room or venue you are playing. In case that's not enough, this cabs sports no less than 3 High Freq drivers (4" speaker, Neodimium tweeter or Ferroelectric Tweeter), all with a 100/50/0 level switch. This means you can choose the high freq driver that you like so match your bass. You can even use all 3 at the same time. It will handle 1200W and sensitivity is102 dB. The low weight is the icing on the cake. The best cabinet in the market in our opinion.
