I guess the two issues with typical dropped ceilings are 1. Rattles at the support connection points
Generally that would be my main concern at higher listening volumes... but you can purchase spring clips (installed above the tiles) which reduce this problem... as well as the fact that not all tiles react the same way.
2. Very nonlinear frequency absorption.
I don't know about being "very non-linear".... it's normal for the absorption coefficient to drop as frequency drops, as it is for any accoustical treatement of limited thickness. I don't know your room responce... but with tall kHorns and low ceilings, i'm guessing you'd be getting quite a bit of mid - high frequency relections off you ceiling... which happen to be the frequencies accoustical tiles could treat quite well. With the right tiles... your accoustical ceiling probably helps in making your ceiling appear accoustically taller.

That hole has been patched it is just needing paint now...
Didn't you fix that back in 2007?... [

Pandora is the best that I have used. Take the time to add input (thumbs up or down) and add artists to your stations, they will grow and get better.
For those who don't have access to Pandora (ie: anyone outside of the USA) there is www.last.fm which also offers user adapted online radio...

I just was offering one up for those who might want to try it.
It's worked quite well for me in the past, i have a couple of these home made guides hanging around. I suppose an alternative to finding a straight piece of wood would be using a small metal (aluminium or other) angle or the like.... but there never seems to be one around the workshop, right when i need it...

I may be late to your thread... but glad to see you daughter is doing so well... [

Great workmanship… and stunning result.... only wish I could hear them...

Even though I haven't been posting as much, you guys are always welcome to drop by...
I've made a couple of changes since those pictures, but I think I'll wait till I've got some of my new speaker enclosures finished up before updating the pics....
Peter... I just messaged you those drawings... -
Great setup !
thanks!!... and it's still a work in progress as i'm currently building a new centre channel as well as cutting wood to rebuild the khorn mains ...
This
is exactly what I need for my future HT room! Any plans to share? Or
did you just wing it? Any tips? Buy melamine and cut to size
yourself? Assemble with screws? Or brace with real wood?The main shelving boxes (it's two stacked units because it is full height) were assembled mostly using a nail gun and some screws in the same way you build kitchen cabinets. Those got screwed into the wall while the shelving is supported on adjustable metal tracks inside those boxes. I did draw this up on AutoCad (including cut sheets)... i'll have to dig up the files at home and send you what i got. I never bothered doing a legend or the like and i skimped on the labeling (as they were for my use only), but it'll still give you an idea.... [8-|]

I'll put my vote in for Morticia Addams as played by Carolyn Jones...

Thanks for the info... truthfully i'm not much of a "prewiring" specialist and I really don't want to have to redo this more than once...
But given the difference in frequency of the signals for analog audio (line level) versus video... would the same cables perform well at shielding RFI and EMI signals when used in that range? In other words... given these wires weren't necessarily designed to shield RFI and EMI in the audible levels... will they?EDIT: would an "inwall microphone" cable like
Dayton MLI-250 22/2 Shielded Mic/Line Cable be best for the audio purpose?EDIT #2: read a little more on the RG6-QS (Quad Shield)... and seems like i pretty good option for multipurpose... [
]Thanks again… and still open to model suggestions…

I'm going multizone in my home, and i was wondering what a good bulk coaxial cable that I could run inside my walls as interconnects?
I'm looking at about a 40ft run and I know I have had some RFI issues with long (50') temporary cable runs in the past. At the moment my main preamp outputs analog only for zone 2... but who knows what the future holds?
How about a RG-59U like the Belden 1505F or perhaps a RG-6U like the Belden 1694A? Anyone already ponder this question?
Thanks...

If you can believe it, I haven't done any waterfall graphs yet... [:|] ... the PC i have in the audio rack seems to suffer from some low frequency hummm that shows up around 20Hz. this was true for any plot i did with three different soundcards (built in, PCI, and USB) so i'm wondering if it's not the power supply (?). My eX kept the portable ... and i haven't borrowed one nor brought down my main desktop yet... so all i got are db readings listing to music.
Like you, i've been pretty busy with other, non-audio related things in my life at the moment... [
]Do you have a foot fetish?
nope... i have a plaster fetish...

Formica,
Classy setup,very clean.
Thanks mate... [

Sometimes my wife and I have movie night all to ourselves and just enjoy cuddling up and enjoying the show or game!
ummm... you sure it was "the show or game"?? [

Thanks guys...
Will the couches remain sideways to the screen?
No, I have little felt pads under the feet in order to slide them around according o how many people we are. For one to two people I leave them as is, cause I like to kick my feet up and lean on the arm rest.
So do you have one of those anomorphic lenses in front of your projector to fit the images onto the screen properly?
No... unfortunately not. I just zoom in so that the image fills the screen so I'm not getting the full resolution when I'm watching a 2.35 film. Surprisingly, though, the original film quality / transfer seem to frequently be more limiting than that. In any case, I'm figuring / hoping that a similar feature will be intergraded into main stream projectors by the time I have to replace it...

It would be awesome if you guys put your pics in that site!!
Good point.... more of us should (i added it to my list of things to do)... in the mean time... these are some pics of my in-progress HT:

Darn! It would have to happen just after my subscription ran out.
d@mn... me too... [
]Seriously... Congrats on making the cover... !!

Mostly electronic music... but a couple of deep, nice sounding tracks in the old thread: Bass extension requirements for 2 channel music http://forums.klipsch.com/forums/p/65771/643768.aspx#643768

going to bull fights on acid.
Wow,you too huh?
Ditto... and i thought i was alone all these years... perhaps we should start a club or forum? other hobbies include Classic cars, Art and photography, Renovations, Design, and Pretty women... [8-|]

The side surrounds, and possibly the backs, are not as important as your 3 speakers up front which are the MOST important... (followed by a great sub system to compliment your fronts!)
If you want to keep the Timbre very close, I suggest a La Scala between your K horns. That way, the mid range horn and tweeter will be the same.
I agree
with Roger... most commercial theaters use similar setups (smaller effect
speakers versus mains) and therefore soundtracks are frequently mixed in consequence. And given dialog (and vocals), keeping the
timber the same across the front is ideal... []

thanks... and the screen is in the 1:2.35 format so it measures about 94" x 40" (give or take an inch) which translates to the 102" range i believe...

and one last one for now.... I haven't taken any with the new Chaise Longue... yet... but i've been busy cutting wood to convert my "D" type mains to something nicer....

another....

A couple of newer pics...
