I'm taken by the Bill Wood's large 300Hz wooden horn....and I'm wondering who might be using similar? This horn features in the up-market Cogent speaker system from Oswald Mill Audio. Field-coil drivers make this rather exotic.

What drivers are best suited? I like the idea of new Altec drivers from Great Plains. The 902 1-inch driver will run from 500Hz all the way to 20,000. But, is this too much to ask of one horn? (I ask because I'm keen to develop a two-way speaker.) If this driver was not the best, then I would use the 2-inch 390 model, and run it from 300Hz to 5,000, then use another horn for the HF's, possibly using the 1-inch 902 driver....or a dedicated tweeter/horn similar to Beyma's CP25.

Bass will be GPA Altec 416 driver in large ported or Onken box. If I get really enthused, I might use the Tannoy GRF-R cabinet, but I'll then need to reassess the driver, as not sure about the 416 for back-loading. The GOTO bass horn is also another consideration...which suits the 416 driver nicely.

Thoughts anyone?

Regards.

Andrew
