Two Subs?

Bo...you should perhaps familiarize yourself with audio terms..."flatten" in this case simply means to straighten a frequency curve using EQ and volume parameters designed into room correction devices. This is based on device measurements that "see" low frequency peaks interpreted by the device as undesireable room reflection generated standing waves, or what the designers of the gadget have deemed to be unnatural bass frequency modes. I assume you used a recording of a Kodo...so disregard the last part of my previous post, unless you really did play the things. Also, I use a sealed REL Q150e front firing woofer, although downfiring woofers can and do integrate fine with mains for many listeners who's ears might differ from yours...140hz is a ridiculously high frequency point for subs, and it's weird you think that should work well...hmm...sort of goes to credibility there.

A year ago my sub was set till 80 hz. It was based on the time I almost only sold Rel subwoofers. You could not use them to higher freq till about 60-70hz. I got the information of Audyssey people. So I start testing with 100 and also 120 hz. And I was amazed that the overwhole sound became more palpable and also more musically. Later I compared 120 and 140 hz. With 140hz it became even beter. Without Audyssey pro I could not have used it this far so easy. If you would have asked me a few year ago to use subwoofers this high I would have thought you are crazy. It changed my thinking about subwoofers. When you do many tests in audio sometimes your perspective changes. With Audyssey pro I have so much more control with subwoofers. When I would not have it, it would be a different world. It made me love subwoofers for stereo. I never thought I would use it for stereo myself. I am very sceptive in many things in audio. But hearing is believing. Audyssey still have no option to use 2 subwoofers for each front channel. Then I would play with 2 subwoofers as well.

There's no Audyssey Pro dealer close to me to perform analysis of my room. Any other room correction systems (for non-rectangular rooms) available on the cheap?

Rel Q150 was the most sold Rel at our shop at the time it came out. I prefer frontfiring. But in old houses with old floors you can get a lot of ( coloured) fun with them. It depends what you like!!

I've never heard the DSpeaker Anti-mode duocore, but it gets good reviews and (I believe) shows room analysis as well as providing correction. Underwood HIFI sells it on-line, and - I believe- provides an an-home evaluation/return policy.

Good Luck
