Post Subject: Back to the upper bass hornsPosted by noviygera on: 8/25/2011

After living for a few years with Edgar 80Hz straight horns, I've had many urges to find a better sounding solution. I have a reason. Every time I turn them off and continue listening without them I notice that something good happens to the sound. It cleans up and becomes more engaging. So I am back to my search for the upper bass horn. I've decided I do not want to mess around trying to fix or improve the Edgar horns, let's forget them.

Upper crossover point is 400Hz. How low will depend on how compromised the design is. I have 40"x35" spot below my mid horns. So maybe 80 to 120 Hz bottom range. Any ideas how to start this interesting project?

1. horn shape: rectangular ok or strictly circular or something inbetween?
2. flare type
3. driver: I am thinking 10" or 12" Precision Devices.

I assume the Macondo upper bass channel is very close to a no-compromise design. I am willing to trade off a little bit for size reduction and a more practical shape but not nearly as bad as the Edgar 80Hz. If I were to theoretically place my goal design on a scale between the Edgar 80hz and Macondo Upper bass channel, my preference would be much closer to the Macondo. Is this a reasonable inquiry?

Thank you,
Herman
