Sound is better when I stand up?

*G*  Ahh, @holmz , you've deduced yet again.... ;)

I've no wingz on my chairs, but parametrics I've got plenty....

An arse aside, my spouse was bemused by how bovines got tested for pregnancy..."You're kidding....?!"  (Cousin involved in that sort of activity noted the glove of the vet....).

Personally (do I have other? Nayyy..), my Walsh sound better here in my orifice if I stand....but they exist on a shelf above my desk, so I have to rise to the occasion to enjoy the higher things in life, living, and the pursuit of....

WNC is slated for 19 F tonight....not yet, but about daybreak, maybe...

As soon as wingbacks were mentioned, I thought as much.  Fabric choice could be a factor, but even leather (or pleather) could still muddy the mix.

Should be nice in VB, but advise 'layers' in clothing....NWS predicts 'yo-yo' temps and that may persist....

Spouse and self are bailing out Xmaz & NewYrs. for SoCal, the world of 2 seasons I left behind long ago...go hang with the familia, spouse wants Rose Parade IRL, Hollyweird, and Palmed Strings in a 2 weak speed tour....

I get to brush up on my combat traffic chops....*L*

"Sticky Date Pudding".....

I've had a couple of those.....

Oh, Desserts....

That's Different. *LOL*

If one like films, then later in Jan in the PSFF, and that and their summer film festival are both good for film loving types.

We wing back, winged horses, and now a winged plane.
What is next? Paul McCartney and wings?

Bar stool?

Coming in late to the discussion, but regarding wanting to understand the wave patterns, if the wingback is made of stiff reflective material like leather, it would act as a high frequency reflector and you would get phase cancelation at high frequencies. If it's curved then it'll act as a concentrator (like a lens or satellite dish or a bowl behind your head).

If it's thick soft plush material, it would be an absorber for mids and highs and possibly even a bass trap. 

Those are my thoughts anyway. Compare to your situation, run some experiments changing the area behind your head with the wing ack, and a sense of what's going on could become apparent.
