Subwoofer Amp


Posted on Apr 14, 2012    8072

The fins were added to a simple flat aluminium panel, and are made from 20 x 20 x 3mm aluminium angle. Their purpose is threefold - they improve the performance of the plate as a heatsink (although this is not necessary with the BP4078 PWM amp), they make the panel a lot more rigid, and provide essential protection for the volume control and phase switch. It also looks better IMO - it looks like it means business, rather than looking like one of those wimpy 50W plate amps you see advertised.
