Remember when we talk about screen size it is diagonal size. So 100" screen is only about 7.3' wide (excluding border). This leaves you with about 2.1' on each side for the speakers.

But yes, you have to factor in the side space when choosing screen size. Particularly if you have a narrow room. One way out is to put all front speakers below the screen if you don't have enough wall width.

How far are you planning to sit away from the screen?

90" screen at 12' is 30.5 deg FOV. So it's an ok size. As pointed out above, your only concern is the side space left since your room is quite narrow.

Most ready made screens come in fixed sizes. 92" is quite common.

Refer to this link: http://myhometheater.homestead.com/Verticalviewing.html

In an ideal situation the middle of your screen = eye level. But if your eye level is 40" high, it means the bottom of your 90" screen is about 16"-18" off the floor. Doesn't leave much room for speakers.

If you see the link, max allowance is 15 deg angle to the top of the screen. If you use this means your 90" screen lower edge would be about 32"-34" above the floor. This is max. To reduce neck strain you can go lower of course.

Next smaller size is around 82" or 84".

For a viewing distance of 12' the min recommended size is 89" (this gives you the 30-deg FOV). So between 80" or 90" I'd definitely go for 90". This would give you a more 'cinematic' experience.

FYI, I'm using 106" screen from 13' distance (my FOV is 33-deg)

Try to mark out the screen size on your wall. You can use masking tape, elsewhere others suggest using a bedsheet. Then at least you can visualise the size of the screen and you can see how the other speakers and your sub fit in.

Nice way to integrate your speakers with interior design!

AV Review just did a group test on blu ray systems.

Have a look.

Nice looking room yonggoh.

Interesting position you have your sub in.

Good rant terranova.

The retail scene in general in Malaysia can do with a lot of improvement. The system here isn't consumer oriented.

A lot of us also aren't experts in designing an AV room, but we just read up and research. You should also do the same. You're gonna invest thousands into your room and equipment, so invest some time also in the knowledge.

It's good to know the basics so you can decide what you want to do. There are many ways to design a room. Even if you get an AV shop to help you do it, you need to be able to double check their advice (hey not all AV shops are experts either and you don't want them to give you wrong advice).

Anyway, my quick suggestions:

1. Place screen on the 4500mm wall.
2. Projector is towards the 3200mm wall. Check on your screen size and projector type to decide how far away to place your projector. Decide on ceiling mount or shelf mount.
3. Your sofa doesn't have to be right against the 3200mm wall. Can be 2-3' away from that wall (better for listening experience also). This still allows your door to open a bit. If your door is going to be a problem, consider changing to sliding door.

You have to look back at logit's postings here (esp about subwoofers) to get the history

Not only language issue but totally unrealistic expectations for the sub (like what htkaki mentioned above). I think once he also talked like he had very high budget, like can afford top end elite subs...

Even if you have capable speakers with good bass, having a sub can be beneficial especially for movies.

1. For movies the bass is normally in the .1 LFE channel which goes to the sub. If you don't have a sub, your AVR must have some way to redirect the .1 LFE channel to the main speakers. Otherwise you won't be getting the bass effects from the LFE channel.

2. Delivering powerful bass needs good amp power. Even if your speakers can go low, you need a matching powerful amp in order to push your speakers to produce that powerful bass. Having a separate sub means you free up amp power to drive the speakers.

3. Even if your speakers can go low, can it go as low as a sub? Or can it produce the same quantity/quality of bass as a sub?

Yeah, it's important to have your own space where you are king and wifey doesn't interfere

yonggoh, how big is your HT room?

It's a matter of setting and loudness whether your sub will overpower the mains.

If you run the sub hotter than the mains then it might drown out the mains. Another possibility is if you listen very loud and your speakers cannot pump out as much volume as the sub.

Very nice nyquil.

Corners are best for the most gain since the sub is near 2 boundaries. But it might sound too boomy.
