hottattoo, I think that is why they invented bigger amplifiers?
Here's a recording using Selenium DT220 one-inch driver.

I'll do another recording with bigger JBL 2445's later. These are sounding very good at the moment...and I'm using cheapy horn tweeters (P-Audio) to test the upper range.

I might try and keep the system three-way....for example, the Faital Pro HF200 comp driver measures very well from 500Hz to 18,000Hz. I've used this driver before in the Bob Crites Cornscala. If I had a few more $$'s, I'd go with one of the new Be models from Radian....very good range recently introduced....but $600-$700 each.

Yes, very nice curve!
I'm surprised the Selenium did this well.

Any smoothing there?

Filled joins with putty, added extra bracing, added wool/fibre to cavities, drilled counter sunk holes to baffles.

Nice build! Also good to see a bass horn optimized for the Altec/GPA 515.

Thanks guys....Lynn, priveleged you'd say so...as I've watched/read many of your projects.

I'm a builder/enthusiast...and love anything big.

I've built Carfrae, Big Fun Lowther, GOTO bass horns, Tannoys, Cornscala, ALtec 620, Altec Stonehenge with 604...just love playing around...and the sound of a big cab is great.

With this bass horn, it's certainly a mroe ambitious project....

I'll keep you posted.
