This project was to replace a “computer sub” I was using in my office along with the excellent CAOW1’s. The Peerless mid/bass move quite a lot of air so do not need a huge sub in a small room.

This is a direct build of Roman Bednarek’s design and for details and other excellent projects see - http://www.rjbaudio.com/Cerberus/cerberus.html

The port flare looks a lot better in real life. The box was finished with bits of spare Silky Oak veneer that needed jointing within the panel widths, I wasn’t to worried about this, or the final look of the port flare as the box will “live” under my office desk. In fact I didn’t have enough veneer on hand to bother about the base.

Result’s

Well the small Tang Bang certainly uses the large xmax it has and the cone moves hell of a lot. I was wondering if the 70 watt amp would be sufficient but I have it cranked at less that a quarter. The cone movement scares the begeebus out of me and I wouldn’t want to rev it too high - but I’m a wimp in these matters and I suspect the TB could take a heavy load.

This is a great little subwoofer for small rooms and I would thoroughly recommend the design - thanks Roman.

Back to the CAOW1’s - I’m guessing those that have built Dennis’s design might say in a small room these speakers probably don’t need a sub and to a large extent I’d agree. Which was why I build this version as they go quite low on there own. But I swap them out occasionally when I’m playing with small full range speakers where the bass is needed and the Cerberus performs great.
