High excursion
with true piston movement for spectacular sub-bass reproduction
The B2550 uses a heavy, doped cone, large rubber surround and a rigid plastic dustcap that can make high excursions with true piston movement. The stacked magnet assembly is rear vented for cooling and is deep enough to allow exceptional peak to peak travel well in excess of the substantial linear capability without bottoming out.
