This is an example of failure
Can not play bass at all

Damping the backloaded horn is not an easy job to do.Is important to begin with 2 steps:
-compresion chamber (careful with middle range)
-begining of the rollercoaster.
Also try to put some absorbing material on the bottom,inside of the mouth at corner.
Begin with a few tiny pillows to hear the diferences....
It will take some time to do the job right..........

insistence on horn length, horn aperture becomes narrow result, ringing has been increased. (become a shortcut horn)
1973 at that time, technology and know-how (even manufacturers) had not been established. (I regret having made ​​too early)

Those are cool! Do you have a build thread? What are they all and are you using an active or passive crossover?

Hi Scott,
Unfortunate, the original build thread was on dead-now webserver. Evolution lasted about 7 years and was centered on re-dimensioned Bruce Edgard's "Show Horns" (from 50Hz cutoff to 70Hz). Mids are Selenium's (HM4750SLF+D405), supertweeters are Eminence APT150's. Bass consists in 3 band-pass units (Behringer B2092A being one of them). All is active, digital, crossed @80/500/5kHz. System tuned for classical, which I'm fond of, and positioned in corners of a 35sqm dining-room, toed 45 deg., subs placed after Geddes method. Thanks for your interest.

New bedroom speakers - based on the sten II's but with a different tweeter and modified crossover. 25mm MDF with a stone maple veneer.

I am very pleased with how these sound.

Just to be pedantic, the CC of a BLH is the room it sits in. The chamber behind the driver is the Air Cavity.
