Re: Some simple Array questions
Eric,Yes, you can use a conventional center channel for SACD and DVD-A. While it may not be the absolute optimum but it would sound OK. A center channel speaker derived from the drivers similar to those in the arrays would be a closer tonal match. I'm ...

Re: Speaker placement
You still don't get it do you!!??I use bandpass subs with a 100 Hz ACOUSTIC low pass in addition to the electrical LP that is in the amps. There is NOTHING of significance above about 100 Hz. Quit trying to top me on everything I say - I think that I kn...

Re: Speaker placement
OK, so you don't have electrical crossover to rolloff your subs. You depend on the electro-mechanico-acoustic properties of the subs to roll them off instead. The distinction is irrelevant; The point is that there is output from multiple randomly-plac...

Re: Speaker placement
This has moved from a discussion about subwoofer placement into a more general discussion about subwoofer crossover frequencies and integration with mains.There are two issues here. One is the use of dense interference to smooth room modes. The other is...

Re: Speaker placement
I understand now that you are really talking about three different kinds of woofers. One kind is used as woofers in the mains, which are to be symmetrically placed. Another is a VLF sub, used to augment the extreme bottom end, rolled off where the main...

Speaker placement
Speaking to the placement issue, how do you deal with the fact that bass and low mids in the modal region are coming from mains? I assume you suggest symmetrical placement for the mains, and probably you place them where they work best in the range above...

Re: Computer Simulation of Room Acoustics
Dear Mr. Parham and Dr. Geddes,As the chief developer of CARA (Computer Aided Room Acoustics) I want to clarify the mathematics implemented in CARA.Dr. Geddes states:"CARA is a ray tracing program. It will not be able to do the LF modal study. Ray tracin...

Computer Simulation of Room Acoustics
I recently purchased a software package for modeling room acoustics. On initial inspection, it's pretty impressive. I am setting up a study of several speaker setups in various rooms, sort of duplicating the Welti study but adding a few more configurat...

Re: Sub placement
I see. But they did specify their bias for mono-bass irregardless of the studies purpose. I was just wondering if there is some consideration regarding that issue.I like the model of 5000 subwoofers in the room; no modes there; nosiree!

decorrelation
I guess the central question would be something like "what really matters regarding low frequency reproduction, and what's the best way to get it?"
Apparently one thing that matters is the sense of spaciousness that good low frequency reproduc...
