For a long time I have thought about making a good Subwoofer. The plan is to start with a small design, a simple sealed box, similar to one of the popular Subs you can buy. Here are a few links I have found: BK Electronics Look in 'Modules and Hybrids'. Nice looking Amplifier modules, and in England I cannot get a catalogue of Subwoofer parts, prices and specs etc from them for some reason The Subwoofer DIY Page v1.1 Subwoofers.org Does anyone have any cabinet designs for a small sealed Sub?
