You know you are dealing with a Class Act when the speaker
maker recommends dealing with the room rather than changing
the caps. And I completely agree with Danny (Why shouldn't
I.. He knows far more than I do... Maybe someday I can be
where he's at now.. And then he will still be far beyond me!)
Dan
I would deal with the 1st and 2nd reflections by use of
precisely located wall hangings. You can have someone stand
at the speaker and shine a laser from the center of the
tweeter and where ever that beam hits that's your first
reflection. You can hang a nice canvas painting or a tapestry
there. They work.. I use a large canvas painting on my one
wall to absorb and it does, well. On the other wall I have
Levelor vertical blinds that work fantastic as diffusors
(rather than absorb they scatter).
Or if you don't mind the asthetics some acoustic foam tiles
work wonders. I just can't see gluing them to the walls in
my living room
On back walls, Book Cases full of odd sized books work well
for diffusing standing waves. And you can make Bass Traps
on the cheap using Chris's or other designs on the net.
