Post Subject: CAD images 45Hz inner surfacesPosted by jessie.dazzle on: 8/1/2008
Here are a couple of shots of how the inner surface of the new rectangular mid-bass horn will look (shown with driver; an AK151). This model is based on a calculation for an exponential horn.
These images do not show wall thickness or bolt flanges.
The inner surface of the mouth of the horn will be 2.30m x 1m (just very close to the size of a 4x8 foot sheet of plywood).
The idea being to go for 3-sided coupling with the room. In other words, to stuff the horns up against the side walls and get some additional reinforcement; they are tall enough that the short sides will couple with the ceiling and floor of a normal room.
Depth is just over 3m with driver and rear chamber.
I will try to make this sort of set up work... The short wall of this room is not wide enough to place the 45Hz horns there too. A long wall set up would place the listener in the extreme near field relative to these new horns... Will try it like in the illustration above.. If it doesn't work out, I'll just move !
I was also going to show the planned construction process (have modeled it electronically in order to get my head around it), but this super PC keeps locking up on me, and anyway it's friday night! Will post it later.
Comments welcome.
