Hi. If anyone is interested, I have a website that describes how to fabricate horns from paper mache. My home stereo uses paper horns to cover 450hz to 20,000hz. I utilize JBL 2446, 2" throat compression drivers in mine, but have fabricated horns for a gentleman using Tad 2002, 1" throat compression drivers. There's no end to what you can accomplish. The best part: at 110db, 1w1m, they're fantastic with tube amps.

The menu to my projects is located in a vertical column on the upper left of the page. Happy listening, everyone.
