After multiple delays, finally, one of my two Official Axiom Demo Rooms is ready; it is the most important one the Home Theatre one. The room is 14'-2" wide by 22'-3" deep. The height varies from 9'-7" down to 8'-2" and 6'-11". As you can see I did not spend money on the aesthetics of the room; I wanted a magnificent sound and a great picture. The way the room looks really did not matter to me; it is only used to watch movies, sports and TV in total darkness.
Front and side walls are regular sheetrock sheets screwed over wood spacers which are screwed to plastic inserts which are part of a poured concrete wall system (http://www.nudura.com/en/HomeOwner/whatisnudura.aspx). The back wall which connects to my bedroom is made of several layers of sheetrock sheets over sound bar, Sonopan sheets, air spaces and concrete blocks. The ceiling is a single layer of sheetrock sheets on sound bars screwed to wooden beams which support a concrete floor above. The ceiling cavities are filled with sound insulation pads. All that sheetrock made the room too lively. Again the floor is made of exposed concrete except for the last third of the room on which a wood structure supports the back row of seats. All that sheetrock and concrete made the room too lively but I did not want to apply special sound room treatment.
To reduce liveliness to an acceptable level I laid down a medium thick carpet without a liner over the entire floor. I put heavy furniture on all three levels even if the front one is barely ever used. It was enough to tame the room and to give it a pleasant acoustic signature. It is still a room which is livelier than the average one but more than acceptable.
I wanted a vey large screen projection system at the lowest possible cost. The maximum size my room could host was a 150" diagonal one in a 16:9 ratio. The solution was to paint the screen; I used the Goo-Systems. I have not done a perfect job but the result is still more than impressive as per visitors' comments. To fill such a large screen you need a good projector. To help the projector to fill the screen with enough brightness I really darkened the room. The front and the rear walls are flat black so is the ceiling. One side wall is the darkest brown I could find and the opposite one the deepest blue available. Finally, the carpet is black with small dark coloured patterns. Except for the furniture on the front row which is too light and reflective (budget limitation) the furniture on the two other rows is rather quite dark and not as reflective. My Panasonic AE-PT2000U has no problem filing the entire large screen even in eco-mode.
The overall appearance of the room can be qualified as plain or sobre quite severe and austere. And now to the sound equipment . . .
An Axiom Epic 80 - 600 Home Theatre Ensemble in a 8.4 configuration (dual center speakers) with each M80v2 supported by its EP500v2 is the core of the system. In front, you have an Axiom VP150v2 on an Axiom FMS-CC stand below the screen aiming at the middle row of listeners and one above on an Axiom FMB bracket aiming at the rear row of listeners. The Axiom M80v2s are installed on each side of the screen on top of a MDF box which hosts an Axiom EP500v2 subwoofer. In each of the two spaces between the main M80v2/EP500v2 speaker combos and the center speaker lies an Axiom EP600v2 horizontal model. Each one of the two corners of the back wall hosts an Axiom EP600v2 in a vertical model. The benefit of two subwoofers on the wooden structure which supports the last row is to provide physical motions similar to the butt-kicker without ever getting overbearing. For the listeners of the middle row (concrete floor) between in the middle of 4 Axiom EP600v2 when the action is pondering at high level . . . you feel your hair moving on your head. On the side and rear walls there are two rows of tracks which the two pairs of Axiom QS8v2 are mounted on. This provide great flexibility in experimenting different locations.
All these passive Axiom speakers are powered by a single Axiom A1400-8 hooked up to a Newcastle P-965 processor. I also ran dual Axiom A1400-8 amplifiers for a brief period and I'm looking forward to add a second one again in my system. I will probably be adding the new Axiom A1400-2; I will keep you posted.
How does it sound ? You have to hear it to believe it ! You are all welcome anytime . . .

Thanks for sharing, JC. I know you've been working on this project for quite some time, so it must be immensely satisfying to finally sit down and enjoy the fruits of your labor. Fantastic choice on your speakers, by thew way.

Excellent news! Now I know why the news was reporting frequent small inexplicable earthquakes around Sherbrooke.

Are you ever right . . . It is immensely satisfying and the performance is phenomenal. I took a few pictures; I'm not very good with a camera. There are a few ones which I think are good enough to share. I'll try to post them later on. I'm trying to tame the Gallery.

On a practical note: with that many high-powered amplifiers (4 subs+A1400) and the rest of the electronic, how many 15/20A circuits do you have dedicated for this room?

Eric, I need to be polite on the volume; abuses have created a lot of comotions as you have read.

Eric, I have eleven (11) for the equipment and one (1) for lights. I will post a picture where you see the wires going to the rack.

By the way; they are 15 amps. Tom Cumberland (A1400's creator) told me that I would not gain any substantial benefits going to 20 amps. Who am I to argue ?

Maybe Ian will come over to your house with a couple EP800's . Is it mandatory that you have to wear a helmet while watching a movie in case the house collapses ? Congratulations on such an impressive setup! You should be very proud.
I’m armed and I’m drinking. You don’t want to listen to advice from me, amigo.
