This is a 11/6 x 14/6 x 8 room used as a home office and listening space. I previously had dipoles in this room, which is why I bought the QRDs for the front wall. The side ones are on stands with casters to access the closets. They do seem to add a slight extra feeling of depth to the soundstage, and add back the highs the absorption panels eat up. Absorption panels at all the other first reflection points, walls and ceiling, traps on all four corners and across the rear wall vaulted ceiling. IB subs in the ceiling/attic for the ULFs.

What ever you do, try to make as many panels movable as possible, to be able to experiment down the road, which is really the fun part of room treatments.

Hi Everyone,

Sorry for being missing in action for several weeks. In the process of looking for a new pair of standmounts. Present floorstanders not working out at all. Room still the same...corner bass traps on front wall and absorbers on sidewall 1st and 2nd reflection points. Back wall "treated" with pillows and large cushions at the moment,  since my bed is very close along side it. On my shortlist so far.... Ref 3a Decapo be or Audio Note K or J. By the way...very nice setup jk@home.

Once again...all your advice and help is very much appreciated.

In my experience, the effects on low frequency control with diffusers is not only affected by depth, but by width as well.  I have used 13 inch deep diffusers that are 8 feet in width and definitely controlled standing waves, as well as enhanced the stereo image as well.  These findings are from experience in the field, not reading a book.  You should keep an open mind until you have tried it for yourself.

Yes, this is true of all acoustic treatments. Large bass waves will easily diffract around small or thin objects quite easily without much disruption to their energy.

Andy, before you replace your speakers please tell us more about them.

I would say that any set of gear can be considerably improved by good positioning and room treatment. In other words, it may not be your speakers but these other factors that are giving disappointing sound. Once you've got the best from your current speakers with positioning and room treatment, then is the time to consider improving gear.

Awesome advice. I have ran into so many clients that have switched speakers many times but not realizing it was actually the setup and how the room was treated that was messing up the sound, not the speakers itself.  Its no wonder that every trade show we do, there are always a bunch of speaker manufactures that stop by our room asking if we have some treatment to loan them.
