Roscoe Primrose wrote:So, in an effort to have a bit more bass extension, and better dynamics, I'm embarking on a new open baffle project. This will be a semi-modular approach, with a bass section consisting of 2 18" woofers in a slot loaded open baffle configuration ( http://www.firstwatt.com/pdf/art_slob.pdf) which will be about 20" tall, with an interchangeable upper section which will hold various drivers to cover frequencies above about 100Hz. The system will be bi-amped, with the woofers run with a low pass crossover, and the upper section, at least initially, run full-range. Plan to start on construction this weekend....

3. The OB woofers I've heard so far were very good, they're worth experimenting with at least
4. Surely you're not immune to the allure of OB, even if it isn't also a line source

2. Haven't read "The Short Article", however, Nelson Pass, brilliant as he is, keeps trying to make sand sound like tubes. I noble pursuit, but a waste of a brilliant mind who could be STARTING with the superior technology! So, while he is probably correct in whatever assertion he makes, when I read anything by him, I can't help but wonder if there isn't an easier and ultimately better solution. Having said that, I'm sure OB has lots of advantages, especially in the upper ranges, but I would have thought that in a very low frequency application, there might be a better way.
