I want to hear what you have to say bout my HT

Actually "bufus", his dimmensions are not so bad at first look. If the difference between 15' and 16' are around 6%-8% difference, that's more ideal actually. If they were closer than 5% and 15'x15', he'd have a real problem to adress, yes!
Actually, Russ Herschellman promotes the 6%-8% differnce in room dimmension ratio's. I concur.
As for your gear, I like your choices well enough for your room potentially, for a "passive system", yes. The hitch is that you have good acoutical treatement considerations in place OR, AT LEAST, you sit closer to your speakers(Proximaly), vs. hearing more room reflections mixed with the original sound propegation from your speakers. This will greatly enhance imaging, dynamics, clarity, and soundstage!...most don't know this. Then, their setup busts all chance for good sound.
Remember, control those "first reflection points" with A PROPER blend of diffusion/absorption, or at least sit closer "in time" to your speakers than the first reflecions proximaly.
Nice gear...

"That Monster Cable PLC has got to go! Also what are you doing for Power, Resonance Control, and Acoustics? You might only be hearing half of what your system is capable of" (Aroc)

Yeah, well none of that really helps you. Personally, having sold those 805's for a living, retail, you'd get better dynamics, focus, and impact with a more efficient set of mains, preferably with dual mid/woofs, and higher efficiency, yes. You still need to run those as "small", but still. Yep, you need a sub or two as well.
Projector? Do you like what you see. There's better out there for cheap these days, and getting better. But on a small screen, many like the 4805.
However, if you do stay with your gear, at least your speakers work ok in that room acoustically, with tall ceilings and all, for more dirrect sound vs. reflected from ceiling. Make sure of carpet between you and the speakers however. Yes, buying subwoofer(s) will greatly help dynamics in your system, and is a must.

Yeah, I've heard his system, and know what it does and doesn't do compared to others. The sound is overall smooth, clear, and "audiophile sounding" mostly, so things are nice and clear sounding. Dynamics bumps up greatly with a Dappolito configured dual-woofer design, and more efficient designs by enlarge. Being that passive speakers need all the dynamic help they can get, there's better dynamic realism, engergy, impact, and weight to be had elsewhere, if that's important to you. (and it's critical to me...cause that's where the thrill and emotion lies)
Also, better focus and solidity of image, dialog intelligebility is available. The counter to the typical 805 design is that people think this design sound more open and pretty for pressentation. That, without the proper acoustics ends up sounding to polite, laid-back, open, faint, and soft sounding for HT dubties...quite the opposite of a good theater speaker setup. To each his own.
Still, in his room, if he is to use those speakers, they work good overall, due to hearing more direct sound vs. relected, with the high ceilings.
I like the Cal Audio stuff here as well.
