I'd help you, Blair. The problem is, everytime I help some guy, his wife hates me because I end up throwing all the shit she's accumulated over the years out of the A/V space. I also re-arrange the furniture and speakers. I even pull most of the furniture out of the room. The guy then hears the end result and is so blown away, he can't wait until she moves out!

Serenity can help you over the phone and email. He does it for a living and uses science. I'm an empiricist myself because I enjoy aural masturbation. smile

We just had a discussion about our theater. Wine on the floor, monkeys and skid marks on my acoustically transparent screen were at the top of the list.
I love how my room sounds but I also know it's never been setup 100% ideal. In the many iterations I've tried they've never been digitally corrected. Best case YPAO, an uncalibrated app and my ears.

My wife claims ownership of 3 vhs tapes, 12 cd's, 2 dvds and about a half dozen bluray conerts in "our" theater.

Blair, I think I know what's confusing you about Trevor's very good analogy. The Ferrari and dump truck speeds are not always constant relative to each other and neither is the length of the towbar (phase angle is a function of frequency - and amplitude too!). Does this help? LOL! It's all so complex not even the hand of God can make it right.

Those VHS tapes of hers have to go. They're really messing with the spectrum above 1.28KHz.

Right.

Lowering the frequecy is like moving the finish line further. Raising moves it closer. The lap length is a function of cycle length. So we need to recalibrate.

We are limited by the AVR with how much delay we can apply. Maybe you cant sync right at 60hz. To get around this you can raise the crossover frequency. Higher frequencies require less delay to cover full cycles.

Head hurt more? laugh

It's all good. I haven't seen it in person, don't really know where to start.
It already sounds good, just one more tweak. Lol.

The VHS tapes have special events recorded on them, SQ isn't the priority with them.

Blair, regarding the VHS tapes, it's not the audio that's on them that I'm talking about. If they're sitting on a shelf, they're affecting your listening because above 1.28KHz, their scattering characteristic is non-linear. So those tapes distort The Family of Curves Axiom worked so hard to shape.

I'm thinking of taking 3 months off work between February and April to busk with my 2-string cigar box guitar in New Orleans. If I stick around in Calgary, I'll let you know.
