I'm playing with my newly acquired toy, the Behringer Ultracurve Pro DEQ2496, and trying to EQ my listening room (24"x30" basement).
Initially, I measured a huge peak of 15db on my left channel around 16kHz. This is with the speakers toe'ed in to the listening position.
I tried moving the speakers around and it quickly became obvious that even a few inches movement of speaker make huge (and I mean HUGE) differences on the RTA. Getting rid of the toe in seems to have flattened the above mentioned peak somewhat.
So it looks like I have some work ahead trying different speaker placements.
In the meantime, I have a couple of questions:
1. I've built "cab extensions" that the 4333's sit on so that the 2405 is now at ear level. I'm now second guessing this move as I have a feeling the peak mentioned above is exaggerated (if not caused) by having the HF at ear level. Are the 4333's meant to sit that high?
2.The DEQ2496 has an Auto EQ feature where it calculates the EQ required to flatten the room. It sends pink noise to BOTH channels and then it EQ the LEFT. Then it sends pink noise, again to BOTH channel and EQ the right. I'm not certain this makes sense as I would think its better to send pink noise through LEFT only when it EQ the LEFT (and pink noise to RIGHT only when it EQ the right). What is the proper procedure to EQ a room?
Thanks guys
Kevin
BTW, my problem was first mentioned in this thread, but I didn't want to highjack that thread anymore
