 The combo's 10-inch speakers, though specially designed and voiced for the Prosonic to handle huge amounts of power, were seen as too small by players favoring 12-inch speakers.The mechanical relay-based channel switching, designed to provide a more pure signal path, produced a large pop upon channel switching at low volumes, unlike other electronically buffered designs—this deliberate design choice was nonetheless perceived as the premier "design flaw" among players.Several of the Prosonic's other quirkier design elements, such as the shared EQ and line-level effects loop, were designed for studio use and weren't ideal for live playing.
