I have a basement room about 24 x 14 x 7'2". The ceiling is mostly
a drop down with very absorbing tiles. Running along the long wall and
coming about 3.5 ' into the room is enclosed and drywalled main
ducting, which drops the ceiling further down to 6'8" ( the remainding
width of 14 - 3.5 = 10.5' has the tiled drop ceiling at 7'2").
I have some Chorus II along the long wall with tiles 7'2" above and
listen to them very near field, about 7 ' back (spaced almost like
equilateral triangle). I found that moving my seating back under the
enclosed ducting sounds worsens the sound in various ways. I recently
found that removing some of the tiles makes the sound more alive and
much more preferable to me, introducing some slight reverb and
diffusion perhaps (from the joists above the drop down?). The rest of
the room is fairly dead with carpeting on the floor and window shades
and wall hangings and furniture.I would like to purchase some
Khorns and put them under the enclosed ducting. On that long wall, I
can space them out about 17' of the 24'. I will have to build false
corners due to the presence of doors and hallways in the corners. I can
move the false corners forward a bit so that the the front of the
Khorns would be more flush with the edge of the enclosed ducting. In
any case, the Khorns would be situated so that they would mostly be
directly incident on the 7'2" tile ceiling
I have a few questions
1. What
experience is there with Khorns with roughly 7' drop ceiling? This
seems a lot less than the 8.5' recommended by Klipsch
2. Is the 3.5' wide further drop down due to ducting
a problem if Khorns are under it? There is not much I can do about this
ceiling structure
3. My experience with removing a few of the ceiling
tiles is really positive. I read here about Berger's Space Coupler
which I could replace some or all of the ceiling tiles with (they are
about $200 for each 2'x2'x3" coupler unit, but I may be able to diy a
fascimile if I need a lot of them). This seems like an interesting idea
as it can add in some sense the space above the drop down extending the
ceiling to about 8'4" (although there are the floor joists and some but
not a lot of pipes and ducting running between the joists). It also
adds some diffusion from the grating. Does anyone have experience with
such an idea? It seems like this problem of low ceiling height in
basement rooms with drop down ceilings and which cannot be remodelled
would come up a lot
Thanks
