$1,000 to spend on room treatment....


My new room 21*13*7 has very bad acoustic: flutter echo of hell (a solid 2 seconds of metallic echo for each clapping of hands), bass resonance and probably more that hides being the first 2 but that will become noticeable later on. I have a max of $1,000 to spend to treat it and already own 4 fiberglass panels 2*4 that I can use to treat mids and diffuse. What do you suggest - price when new to be consistent? There are some room kits that seem to fit the bill (www.primacoustic.com) but I need guidance on this. Tks.

Beheme, you should not consider this the end but the beginning.

Personally, I'm a little slow at making adjustments in my own system as it took me 9 months to find the 'ideal' speaker location. I've not moved them in almost two years and I'm sure I still don't have the optimum placement.

It takes me a bit longer because my speakers are sitting on Star Sound's Audio Points and my speakers are about 145 lbs. each. And believe it or not, there is a very real and very audible difference every time I move my speakers as it literally take 6 to 8 days for the Audio Points to properly settle back in or break in all over again with their connection to the floor. So with these 3 things, I'm always hesitant to move my speakers or my racking system.

Again, you only have a 7 ft ceiling, hence the greater the opportunity to reflect off the floor, then to the ceiling.

I'd like to suggest the thickest carpet pad underneath the thickest rug/carpet.

Keep moving the speakers around a few inches every few days to find an even more optimal location.

I don't know what speakers you have, but if your open to placement suggestions, I'd like to recommend this as a starting point:

Locate the speakers 5 1/2 ft. from the wall behind them and
2 1/2 ft. from the side walls. (All measurements are from the front/dead center of the woofer driver).

This should give you about 8 ft between the left and right tweeters.

Move your chair so that your ears are no further than 9 1/2 ft from either tweeter. This will give you a slight nearfield listen which usually is ideal anyway.

Toe the speaker in toward the center so that the tweeter axis crosses right in front of your nose.

If your rug leaves bare floor exposed anywhere in the front half of the room, throw some big cushions on the floor in the corners behind the speakers, and throw some cushions, pillows, or comforters/blankets (throw not folded) on the other exposed bare floor spots in the front half of the listening area (from the chair to behind the speakers).

You might even loosely spread out some thicker blankets on the floor to assimulate a thicker pad/carpet between the speakers and listening chair triangle.

Uppermidfi may consider this overdampening and he'd be right. But I'm just trying to offer a suggestion to demonstrate what your room might sound like if you had thick wall-to-wall carpeting and carpet padding.

Who knows, if you try these things and post saying this experiment brought a dramatic improvement, maybe uppermidfi will buy one of my racking systems. :)

One clarification I should make regarding my previous post. When I stated that the room's acoustics and treatments only account for perhaps 20 - 30 at most for a system's sonics, I also made that statement with certain assumptions or givens. Thick carpet padding and wall-to-wall carpeting is one of those givens.

Hope this helps,

I'd love to buy one of your racks but what will I do with my Star Sound rack then???
Well, uppermidfi, I have a suggestion or two but Robert at Star Sound may not appreciate it. :)

Actually, Star Sound is an excellent company with true performance-oriented products. You may have noticed that I use their Audio Points everywhere on my racks. In fact, my racks are essentially designed around the Audio Points.

Stehno, I bought a thick wool rug yesterday and with speakers 5ft and 2.5ft from walls, my test CD shows some pretty good response except for the bump at 200-250 Hz that some bass absorber should help with. I relocated my panels and I must admit that some work and $150 on a nice thick 6'*9' Ikea rug moved me 70% into the right direction. Will continue and eventually post pics so anyone can send tips about panels. Next 2 panels will go on the ceiling for sure.
Beheme, that's good news. I would suggest also focusing on the parimeter of the front half of room that is not covered by the thick rug. Decorative pillows can help.

Regarding the bump in the 200-250 Hz region and to further improve the sonics, I would suggest you continue experimenting every few days with speaker placement. Eventually you'll find the best location and/or you'll eventually give up realizing you can't improve much more with regard to speaker location and the speaker's interaction with the room.

Thanks for trying some of my suggestions and despite your room's issues I remain committed that the room's acoustics have far less influence on the sonics than most are willing to admit. But that commitment is obviously qualified with the assumption that a given room has certain basics already addressed such as wall-to-wall carpeting.
