I'll admit that I did not get this one built by myself, but it is my design. I've got the wood cut, just been too busy with other things. Much thanks to Todd (radman12) for taking the plunge and building this on my simulations and speculations alone. I was able to visit with Todd on Friday and measure the results.
This
is the design I posted in the Shiva TH thread, it is a single Anarchy driver in a folded tapped horn.
Remember the three fundamental parameters we get to choose two of at the expense of the other?
Loud
Low
Small
I chose low and small. Heresy - I know - I sacrificed SPL.
The idea was a "rest of the world" type of sub - reasonably sized with respectable performance. A pair placed along walls or in corners should be adequate for 99% of the potential users. That last 1% all post in the forums I frequent, and are all reading this, so this is not a high-powered monster home theater sub for you. It should be a decent little sub and it really is designed to be used in multiples. A pair of these in corners or along walls should get to 100 dB at a typical LP from 25 Hz on up with under 100 watts per driver. Four should do reference levels plus.
He's got a build thread over at
AVS, I am working on plotting the measurements now.
