One minor tip now that you have the 8C's with your SubMersive. With more headroom in the mains, experiment with reducing how hot you have the subwoofer running and instead listen that much louder. IOW, reduce the sub level by ~3dB and raise the listening level ~3dB. You might have to do some tinkering, but you might find that you get much more impact and exciting dynamics with more of the detailing upper frequencies to go with the low end power.
Have a link to this Sunday's GTG?
I actually do this with my setup at home. I found the details were being lossed, so I raised the mains level and everything lined up nicely.
We didn't do a thread for it. It was very simple. We had my old Triple 8's vs the DIY Soundgroup Fusion 12's vs the Coherent Audio Model 15's (large tower with a Radian 15" coax and beryllium compression driver, rear ported). All two channel crossed to subs at 80hz with an Audyssey calibration for each.
I was in charge of the playlist.
Rebbecca Pigeon - Spanish Harlem
Lord of the Rings - May It Be (raw recording)
Bob Marley - One Love
Dire Straits - Money for Nothing (SACD rip)
Pink Floyd - Money (SACD rip)
The Eagles - Hotel California (SACD rip)
A dynamic drum recording
Phil Collins - Against All Odds (DTS MA concert)
Queen - Love Of My Life (live)
John Williams - Jurassic Park ochestral recording
Hero - shelf scene
Open Range - Shootout
War of the Worlds - Pod Emergence
Everything timed to about 30 minutes.
Needless to say, the Fusion 12's had the best clarity and soundstage of the lot. They were the easiest to listen to, with equal or better details than the other offerings. They inspired Nikko and I to go DIY with the SEOS 15, DNA360, and AE TD15M. Waveguide and CD ordered already. Josh with be building our cabinets.
If I had the funds, I'd have a full Seaton setup. I'll just have to try and get close with DIY, MiniDSP, and Dirac Live until I can get something Mark makes.
Mark, have you thought about using a beryllium compression driver with your speakers?

Not sure if by design, room interaction, fluke, but the Cat 8's blend a lot better with the subM than the CX-15's did.
I'm going to try to get the 8's to nikko's place sometime early next year.
I hear you, bud. I'll be there with food and drinks. Nikko will have the Sentinels running by then. Should be a great comparison.
