Lightbulb Interesting OB speaker project

Stumbled on Steve Deckert's Zen Open Baffle project the other day. It features a fullrange on an Open Baffle along with a resonance chamber for bass augmentation.

See: http://www.decware.com/paper93.htm

Personally I find the simplicity compelling. Anyone tried to build anything similar?

as you say, an interesting idea, but I think not so simple, difficult to get the tuning right and of limited application. When he talks about "the absolute purity of a single driver", - well, I think you'll get lower distortion by going 2 way, and if you're having to built a resonant chamber anyway, you're back to a BR enclosure, with solid bass....
Impedance varies with frequency, use impedance plots of your drivers and make crossover calculations using the actual impedance of the driver at the crossover frequency

Default Some wild thoughts

Hmm, I wonder if the QM10 by GURU Loudspeakers (http://www.guruproaudio.com/newguru/?page_id=10) uses a similar approach?

The QM10 have a 4" woofer and it is known to produce unbelievable potent bass for its size. (Some opinions : audioasylum , SonicFlare ,.. more on google)

I think I remember from an interview that the designer actually used the term "helmholtz resonator" rather than "vented/ported box". Just speculations... so far
