very small room - mixes translate a loss in high frequencies

[axemanchris]

Hey there!

FINALLY! SOMETHING THAT FEELS LIKE SIGNIFICANT SUCCESS!!

Okay, here's what I have done. I figure that, recording in the room sounds good. That means that my treatment is very much in order. Mixes coming out wonky must (mostly) be (as was suggested) speaker placement.

I moved them this way and that and back again and to the middle and this way and that again, using various combinations of speakers standing and speakers on their sides and ultimately settled on what I wasn't expecting:

Woofer domes about 45" apart. Distance from dome to ears = about 27". Basically, getting them as far as possible out of the corners of the room without sending me back to the middle of the room, and with me being close enough to the speakers to minimize as much as possible the actual "sound" of the room, with that big nasty node around 100hz. (speakers standing)

I ran a few tests and had some significant improvements. There were still some trouble spots, so I adjusted the volume on my sub, and for the first time tweaked the EQ on my power amp - 100hz up just a hair; 1khz up about 1/3 of the way; 10khz up about 1/3 of the way.

Far from perfect, but a damn site better. There are still a couple of crazy dips, but not nearly as bad as they were (the worst one covers a distance of about 7db instead of 14db!!). The big drop off at the top end actually makes me happy (I think....) because it's the top end of my mix that tends to be dull. Having it drop off (yeah, even with some EQ on my power amp) will encourage me to add a little more. Perfect. (I hope I'm right about that....)

The waterfalls look encouraging too. The RT60 time looks better, as does the distribution across the bottom end from 20-260hz.

Now that I finally seem to be getting somewhere, what could my next step be? Am I right about my thoughts about where I am right now? Any other guidance?

Appreciated, as always;
Chris

Update:

I'm considering the next step towards improving sound in this space.

I'm looking at getting a sub to power my Yorkville YSM-1p monitors.

This thread contains the size, shape, construction, and frequency response measurements of where I am at now.

Would a sub help matters in my room, or is my room too small for a sub?

Thanks!

Chris, you should probably post a link here to your other thread, and vice versa, so they are tied together. Otherwise you might lose track of what is where! And people who are following your thread might get confused too....

Good point....
