room treatment effectiveness

The room is 14W x 14.75L with a vaulted ceiling that is 8' on the left to 11.6' on the right wall. The right wall is 7" tall with a soffit that sticks out into the room about 2' and then up for another 1.5' for a total height of 8.5'. Then the upper portion of the wall is open into an adjacent 10W x 25L room.

I tried moving the seating position out by a couple of feet and that made things worse. It seems like the 200 hz note is loudest centered between the speakers and several feet out from my listening position which is close to the wall. The corners of the room are less affected. I don't like the speakers in my face and having them positioned 8' into the room just won't work for me.

It's odd that one speaker has such a pronounced peak and the other does not even when placed relatively the same in the room.

It turns out when you are dealing with modal characteristic it affects it everywhere except the null points, which you don't care about anyway.

Thanks for correction. It illustrates your point about your services and their value.

In a digital based system,the Z-Systems might do the trick:RDQ/RDP.

I went the DIY route and I am very satisfied. I used Jon Risch's recipes on his site. The biggest improvement was in imaging and it was huge. I also treated my cathedral ceiling and that was huge. I have 7- 18" diameter 4' tall bass traps in corners and 4- 4' X 2' X 4" thick along the ceiling apex. My investment in time was around 10 hours and the money was less than $250. DIY doesn't take many tools, is not that difficult and has the rewarding factor plunking down the credit card does not. You comment regarding measurement differences a good bit. Since most people don't have the capability to properly measure before and after I'm not sure that's as important in the same way comparing specs of two $10K digital platforms means as much as the potential buyers choosing between the two by ear. If you are going to buy pre-made I too recommend using the Rives forum on AA to get opinions from those in the know like Ethan and David. Good luck!

I'm in the same position you are. I need to address some specific bass loading issues and I have been considering treating my room with bass traps. However, my audio dealer friend (whom I have great respect for) has informed me that, unless the traps are EXTREMELY large, they will have no effect on the lowest frequencies, which are, in my case, the frequencies that are causing the problem. The size of my room will not permit me to install very large traps (I'm talking about several feet or more in thickness) and traditional sized "bass" traps will only have an effect on the frequencies that are not an issue (the "upper-lower" frequencies). In layman terms, if I have a low frequency problem, I certainly don’t want to leave the low frequencies and reduce/tame the middle frequencies… This is disappointing to me, because I was all ready to order materials to build some DIY traps. If you haven’t already done so, you should test your room to find the specific “problem frequencies.” You may be able to solve your problems with broadband absorbers and traditional bass traps. However, it is the low frequencies that present the biggest problems. Make sure you know what frequencies the traps you plan to use will truly impact.

If anyone has read this far in my ramblings, I would like to take liberty with Rhljazz’s thread and inquire about room correction devices. I have searched these forums and I believe the consensus is that any equalization is undesirable. What about a custom devise specifically designed to filter the known problem frequency/frequencies? I think I know the answer, but just how, and to what extend do such a filtering device degrade the Sonics?? This may be beneficial to you too Rhljazz.

Thanks.
