Thanks for the pointer. Unfortunately, I am a bit constrained with what I can do in the room beyond movement of the speakers a few inches in various directions.
Good point that speaks to a broader topic (mods, feel free to move this post to another area if you like).
I ran across the Cardas 'Golden Triangle' placement article some time ago, read it, thought something akin to "That's nice to know but it won't work with my world due to resource constraints", and moved on. In audio as with other areas, I think it's helpful to know what's ideal and apply it within your own paradigms as best you can. Resources - space, $, time, etc - are finite. Some persons have the ability to build a room from scratch, some can use an existing room and work within it somewhat (my case), and others may have to share the audio-based room for other uses.
BTW - this is a great thread and I hope it continues. Fascinating how Alan's products seem to promote better audio, as attested both here and in the AC threads. Love the DIY filter cost and its ease of application, too!
Alan - sorry for misspelling your last name in my earlier post - mea culpa!
