"I doubt you're getting flat bass response."

Duh, who is?? However, very precise placement has mitigated the most obtrusive nodes and balanced the bass vs. the midrange. Moving the speakers fractions of inches can excite nodes

That's way less important than the phase/comb/IMD effects that so gravely impact our musical enjoyment. When you take care of these issues, gone is the harshness, fog and veiling caused by these distortion components.

Shadorne, I don't know how to measure it or demonstrate it, but I believe there is IMD caused by the interaction of the two speakers with each other, not the room.

As a musician I often hear beat tones and difference tones when playing with others. These same kinds of things are going on between the two speakers. I've also experience the power multiplication when a group (say five trumpeters) gets totally in sync, totally in tune and playing with equal resonance. It's hard to explain, but when you experience it it's unforgettable. Anyway, getting the speakers ideally placed within their acoustic space and relative to each other is very important, no matter what we call it.

Dave-

Once again it would be interesting to see the frequency response of your Sumiko Master Set placement measured at your listening position.

With your rear ported speakers a foot off the back wall, I'm
sure moving your speakers fractions of inches will excite room nodes. The manual for your speakers(http://www.sumikoaudio.net/va/manuals/BeethovenManual.pdf) makes this very clear.

Using the TacT system, I have flat bass response down to 20hz using no boost. Speakers are placed to optimize imaging. I have digital EQ and XTC available, so I don't have to suffer with poor recordings.

Yeah, but you suffer with IMD, comb filtering and other artifacts that are much worse than any EQ issues.

You seem to have no idea what I'm talking about. To that it avoids exciting bass nodes it has a little to do with EQ, but it's mostly about removing distortion.

Dave

Dave-

You have no idea how the TacT system works.

You have no idea if my biamp'd system is suffering from IMD, comb filtering or any other artifacts, you've never hear it.

Glad you happy with your sytem, but I'm always amazed that people who claim big improves in their systems, refuse to take any measurement to verify what they're hearing.
