Calbear,
Just finished a 122" diagonal 2.40:1 (BF Lite -not S-I-L-V-E-R) Theater with Panamorph Lens/Motorized Sled. JVC RS-100 PJ. Also w/15' x 17' FO Star Field. Tray Rope Lighting High & wrapped around Platform down Low. Top-o-de-line Denon A/V Pre-Amp.($7K

) Carver TGA2400 Amp (700 wpc x 7) Tactiles in Platform w/700 wpc Behringer Amp. Twin Outlaw 300 watt LFE-Plus Subs - 44 Audio Transducer Drivers total. 8 center - 8 ea.for R & L Mains - 4 for R & L Rears -4 for R & L Center Rears. (...certainly NOT chur THX-Ultras, but "Kickin' nonetheless!)
All the above shoehorned into a 18' x 16' area.

Ya know, I'm barely able to wait for a few Members to get to see your Theater. (myself included) Your Decor is so over the Top, it's the epitome of what a Themed Theater could/should be.....and then some.

And that Star Field Ceiling seems to Blaze forth like you cannot believe!
But the 16' S-I-L-V-E-R Screen......? Now that should/will elect a few gasps, if not for anything else but because a few here have STEADFASTLY discounted it's viability for use with the RS-1. Seeing is believing though, and at 16' wide there will be plenty to see.

BTW, did you ever get your Anamorphic Lens and Sled? Or are you hopelessly hooked on that Gawd-awfull big 16' x 9' er?
