I do remember Apogees on Krell MBs on demo in Melbourne and picking that the absolute polarity was out. Much surprise when it was switched and was right.
Ported speakers' Q at fb is more important than that they are ported, imo. A critically damped or over-damped alignment works best IME and the corpus of reviews seems to confirm that.
I have heard quite a few 63s over the years and can usually get them a lot better in a given room. I've done two set-ups with those Scandinavian dipole woofers, and they needed to be pointed almost at right angles to that used for the main's midbass and on up. Which kind of made them useless as stand-subs. Both owners were a bit peeved but bought new stands, ;-)!
I'd only be guessing but in much larger rooms this might all be easier.
Distributed subs near corners and under my mains is where I am going, with the tower of spheres plan.
Note that a post in response is preferred.

This need an explanation? Something that works. Hearing is believing. It'll stand measurements, too. For when your cabinets don't have seriously rounded edges. Waveforms shorter than the width of your cabinets are not diffracted, they are absorbed with the use of what you see on the speaker baffle above. That just leaves the pure signal (i.e. what the microphones captured). Imagine how diffracted waveforms could be mucking about with the delivery of everything upstream of them, what your system is working in earnest to deliver. Well, remedy that and then you won't have to imagine. Your recordings and your components will thank you.

Actually, I am surprised he left out the full contact information in bold letters, a link to a youtube infomercial, current pricing, and ordering information.
For those who feel the need to put felt on their speaker baffles - there are a number of easy supply choices (in addition to the one continually re inserting himself into this thread) to assist your creative urges to modify your speakers.
Here's a popular supply choice: www.mcmaster.com
Felt on speaker baffles is not rocket science. With a little dye and an F10, F11, or F13 sheet of felt, one can experiment to their heart's content.
Hopefully, the next unsolicited post in this thread about BAFFLE ROUNDOVERS...HINT...HINT...HINT...(JIM)... will be on topic and not focused on someone's semi lucrative side job... (massive eyeroll)
And a massive raspberry to you, sir. Just kidding, I thoroughly enjoyed your post, someone should get your dander up more often, and I don't mind being called an opportunist. Plus, the info you provided for DIY'ers is solid. That's kinda like the way I started with my own speakers.
I'm wondering, are you and Tim taking about the same thing? Frequency response and/or time and phase issues? Diffraction is insulting to both, right? What, then?
