Hi Robert,

Thanx for the clarification; much appreciated. You're essentially doing what Chris does. The bass routing/combining and subsequent time alignment has already occurred (and in that order) inside the 950 before you pass your mains & sub channel info to the ICBM. Done this way, very little (if any) bass re-routing occurs after the time alignment.

What I was wary about was using the ICBM as a full bass management tool after you've time aligned your speakers using the 950. In that case, you'll be taking signals form the mains, centre, surrounds & LFE channels each with their own individual delay and combining them. As opposed to your set-up, the above configuration can lead to all sorts of phase & timing problems.

Of course, you may not be experiencing these problems because you're not doing heavy duty bass re-routing & combining with your ICBM. However, think about the impression others are getting about your experiences. Folks, like me for example, read that you are using an ICBM after the 950 and that you are not experiencing any of the possible problems that can occur, and then get the impression that they can do the same. Do they know that you're not using the ICBM to combine bass info from various channels? If not, they may be in for a surprise when they hook up their ICBM between their 950 and their amps and expect everything to sound like a coherent soundfield.

You may want to clarify this at some point (even if it's only at HTF).

BTW, as to my passion about time alignment, let me ask you a simple question: do you use time alignment on the receivers or pre/pros in your home theatre? If so, why?

Best Regards,
Sanjay
