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.

Aloha

You haven't proposed a measurement that would verify improvements in IMD or comb effect. I'd love to measure it, but I've never read of anyone doing it. If there's a way and some resources that you could point me to, then maybe I could measure it with the help of the Colorado Audio Society.

I've read much about TacT and I'll leave it at that, given the issues being aired over at the Asylum.

Unless you've addressed IMD or comb filtering in your set up, then you almost certainly have it.

How does bi-amping impact IMD and/or comb filtering. Seems like adding devices to the signal path would increase the chance of IMD, in particular, rather than decrease it.

Dave

BTW Kana813 I looked at your system and see that you did, either on purpose or intuitively, address comb filtering and to some degree IMD by moving your main speakers way out into the room. Then you offset the bass loss with subwoofers. I assume that you attenuated the bass nodes electronically.

I agree that your method can work reasonably; however, I suspect that further refinement of the main speaker placement using Master Set would further improve your setup. Integrating the subs is often problematic, but something that can be addressed with some work.
