For T30?

IMO, T30 and its cousins dont have much to say about small rooms. And they have even less to say whether when music is playing whether it sounds dead or not.

Ok then we have two votes now. NO need to worry about this RT30 anymore.

Yes, let's move on, please. Plenty of other more relevant things to worry about.

Jerry you pointed out once to take Channel+Sub reading to see how they work together. Before that, I always used to take reading of each channel separately to see how that channel is working with sub.
Question: What's the difference b/w looking at a channel on its own vs channel+sub? Running only channel includes sub response so then why do we need to include sub as another channel?

You misunderstood. The proper procedure is to measure a specific channel, say the left speaker, with the speaker set to "small" and with a crossover. The sub, by virtue of bass management, receives the frequencies below the crossover, so the measurment results in a combined left+sub, and clearly shows the smoothness of the splice between the two.

It would be a mistake to add the LFE channel to the measurement, so don't know where you got that idea.

Probably from misreading page 85 of the (new edition of the) guide.

Downloadable FREE demo discs: http://www.avsforum.com/forum/150-bl...=bd9+demo+disc

Did you really need to quote that entire post in your reply?
