PERFORMANCE COLLECTION Powerbloc2 ULTRA
Legacy's PowerBloc2 ULTRA is a dual monoblock design featuring independent power supplies that double the current capability of the original PowerBloc2. With the added heat sinking of separate ICEpower modules, each channel can deliver peaks of 1000 watts into speakers like the Focus SE. These high-current modules are the same ones found in the incredible Focus XD.
