False wall:

Right in front of the subs will be built the false wall to support the 102" screen. I will just do something simple like everybody. There will be a wood frame for the screen and for the fabric around. I will use a black tissue that it is quite porus as a fabric. This will indeed hide the subs and the (ugly) window a/c.

I will have to build a (screen) wide equipment rack to house the center and equipments. It be place right below and in front of the screen.

Regarding the fronts, wife believe seeing them is better than hiding them (she likes their look). I believe the contrary but hiding them behind the fabric requires additional wood work so that the frame will have a Z shape to house the fronts.

I have not decided if I should follow the wife or not, but it seems quite easier that way and it will also allow me to move the speakers (will I need to do it??...I think not).
I am not sure how wide and thick should the wood frame be I was thinking 4" * 1" polywood.

New DVD rack used as a projector stand:

The DVDs I used to store above the subs will have to find somewhere else and so I thought of building a wide rack (something very simple like a bookshelf) and so it will also bear the projector. Through distance should be around 12'.

Room Colours:

You can see the colours in the photos. The sidewall are yellow and ceiling is white. With a 102" screen I don't know if the PQ will be affected by the white ceiling ...I was thinking of changing the colour to brown...but I might wait to see if I really need to do that.

Acoustics:

With my CRT the fronts were quite far from the side wall (3 ft+), and while my room is not treated the sound was not overly bright or so. I moved the fronts back against to the subs and closer to the sidewall (1.2 ft) to similate the sound as if the screen was there and I noted some unclarity in the sound and propably some harshness in the 1-2kHz range. this specially shows up when I listen to loud music (and I do that often).

I guess that this is due mainly to early reflections from the sidewall and propable the subs as well.
I have also visited a showroom with calibrated acoustics (as I was told) and it seems much more dead and quite (I liked that).

I do not want my HT to be perfect but at least I need to have a decent sound.

I have read quite a lot about that and it seems that I need to treat at least the subwoofers side (that is just behind the screen) as well as the early reflection points (I guess will be 2 feet * 4 feet after the subs)

Here is a picture of a material that is available here and that I used in the insulation of the subs (see photo). While I don't know the name in English I describe it as a spongy material (it really feels like a sponge to the touch)... and I believe it is an absorbtion material.

I am planing to use 2" think for the sidewalls and 1" thick for the subs.

Here are some questions:

- While there was never an agreement between the big names of this industry on whether the front wall (behind the subs) should be insulated or not, I do not know if it should be insulated.

- Should I add some insulation on the rear wall (below the upcoming rack/bookshelf)?

- should I add add some insulation somewhere els along the sidewalls below the wall carpets? (see photos)

Suggestions will be highly appreciated.
