Since then, I have had the good fortune to discover a couple of aluminum horn tweeters inside Magnavox 1S8730 speaker cabinets.

The plywood horns are even more efficient since I enclosed the back of the drivers.

I have not yet built bass horns to go with this setup. For the time being, I am using the bass drivers in a pair of KLH acoustic suspension speakers. I disconnected the midrange and tweeter drivers in the KLHs and the twelve inch woofer and crossover handle the bass quite well. This setup is "bi-amped" with a Lepai amplifier for the horns and a second Lepai amplifier for the bass.
The volume control for the bass is set quite a bit higher than the volume control for the horns because the horns are more efficient than the KLH bass drivers.
Just today, I listened to the first part of a CD of "Romeo and Juliet" by Berlioz. This sounds fantastic.
