room treatment effectiveness


Before I spend money on room treatment, I would like to hear of positve/negative experiences and whether the results are objectively measurable or merely subjective.

My local dealer had a sound room (now a storage room) with a pronounced 100hz boom and he said they installed 16 inch tube traps from floor to ceiling in each corner and the measured difference was only .5db which isn't much. I don't want to go down this road.

I have looked at GIK acoustic and their products are reasonable priced. I have read some favorable comments on their products. I'm sure there is a limit on what can be done with add on products. Are they all good for a few tenths of a db or can one expect to correct for 5 or 6 db?

I am fairly late in responding to this thread but here goes.

We often hear that the room constitutes to about 50% to the sound apart from the equipment and speakers, and I totally agree with this statement. I've recently made a huge discovery in moving 4 pieces of RPG omnifussors to the front wall(behind the speakers). They were previously at the rear wall. Since I have a projector screen at the front wall, I can only squeeze in the diffusor panels at the side of the screen just behind the speakers. To my surprise, the sound suddenly takes on a realism so startling it's amazing. The struck of cymbals and percussion sound so real it's spooky. The sound is like coming from the side walls rather than from the speakers. Also, the highs are suddenly less piercing and it's wonderful to be able to crank up the volume higher without feeling any discomfort or strain on the ears. The differences are noticeable and you don't need "golden" ears to hear them. I don't need to strain my ears to perceive the differences unlike with cables and tweaks. My gut feeling tells me I will obtain greater improvements if I were to place another 2 pieces of omnifussors at the middle of the front wall. Unfortunately I can't do that since they will block the projector screen.

I have experimented quite a lot in my dedicated room and I now have absorption panels at both side and rear walls with some diffusion at the front wall. I have taken a look at your room and you do have a great system based around the N802. I guess placing treatments at the front portion(behind the speakers) is out since it's the doorway. In that sense I suppose you may be compromised at what you can achieve to improve your room acoustics. But one thing is for sure, room treatments have made a positive impact in my system as it would to any system. The question that remains is what treatment to get. From the way I see it, there are only two ways you can go about it which is either to buy and experiment yourself, or hire Rives services. :)

Now I need to figure out what to do next with the ceiling .........
