Hey,
Panos tried to discuss this matter in 2005 in this thread:
http://www.audioheritage.org/vbulletin/showthread.php?4915-Front-horn-loaded-bass-reflex/page2
Anyway I found this thread searching for info.
At the moment I am designing a midbass horn with small dimensions due to lack of space. I have a pair of 150Hz Lowther-style Tractrix-horns standing in my garage, the
are the same type as Bo Hanssons at Opus3:
50034
I have also a few 414-8A in my stash to be mated to the horns and a bassreflex. Due to the Altecs qualities we shouldnīt expect to high upper rolloff. Shelving, like in a fullrange, shouldnīt be a problem as the BR only fills in just where the horn starts to fall.
The upper rolloff shouldnīt be a problem together with 2482 in these horns(note the driver at the bottom), also in the upper right corner you get a glimps of the midhorns:
50033
This is a sim of the horn, box is 40dm3. Note, it will be big compromise even if the design could be bettered:
50035
My friend Hoktuna has built 816īs and together with 416 he is quite satisfied with them used as mids down to 100Hz. Also with the same midhorns as I have.
Is there anyone except Panos29 who have tried the concept any tests? We can forget anything but midbass-systems.
