I dunno about you but I'm doing about 145" with sitting position 17' away and I'm ok with it... so my suggestion to you is to get someone to hold the projector to project the movie while you are at your sitting position 13' away to see if you are confortable with it. If you like it go for it, else either move your sitting position further out or go for smaller projection screen.

My 2 cents.

So true! So true ! Selling the place pretty soon so I think the next owner may appreciate something more 'flexible' vs something so permanent

Thanks

120" screen from 13' away is near the limit. It's doable if you like the 'up front' experience.

Are you running 5.1 or 7.1 setup?

Yes, it is advisable to have the rear speakers a few feet away from your seat.

jchong,

Can I put up a 90" screen on 11.5ft width wall with seating position at 12.5ft? If not, what is the best screen size, 80"?

I was thinking of ways to cover up the lights and such but prefer it not under the screen...neater for me. But I have a little balcony that might fit all the equipment. Will wall up the balcony for this purpose. it's about 5'x4'. Think would need a IR extender to transmit directly into the AV rack.

yeah...i like the in your face kind of experience...but so much till i have turn my head just see things going on the side. i will duct tape the wall to simulate a 120" screen and sit 13' away.

will be 7.1 setup....good to have 2 sub woofer?

I will gather all information and with intended floor plans for my HT room and create a topic to get feedback and suggestions.

A 7.1 setup uses 1 subwoofer.

I was asking if we can install 2 woofers. instead of 1

Then it won't be a 7.1 setup.

The main factor will be your seating distance. At 12.5' away you can take 100"-110" screen.

Generally speaking you should aim for minimum a 30-degree field of view.

Having multiple subs can help to even out the frequency response and also improves the performance headroom.

Now that is the answer i was looking for. thanks. Gotta read up on the positioning then.

Yup, setting up multiple subs to have them all integrated properly is quite an art. Positioning is one factor, then setting phase, crossovers, etc...

One way to make it easier is buying a separate sub-equalizer like the AS-EQ1.

SMPTE recommends a 30º viewing angle, while THX recommends a maximum 36º viewing angle for a more involving image, and a minimum of 26º.

Find a whole at hurt place...

Don't you feel 100" screen with viewing distance at only 12' a bit too large to our eyes? They say if screen too large you will feel after hours of watching a movie.



Can you elaborate on 30 degree viewing p/s? Thanks.

Just found a site that can do the projector calculation. Since most of users here are using Optoma HD65, so I use HD65 as an example. http://www.projectorcentral.com/Optoma-HD6...culator-pro.htm

30 degree field of view means the screen width should occupy 30-degrees of your vision. It's hard to visualise I know.

Easiest way to calculate is to use this tool: http://carltonbale.com/home-theater/home-theater-calculator Download the Excel file.

100" screen at 12' = 33.7 degree FOV. Still acceptable, but depends on each person.

Thanks for the link. I will study it.


I guess one more thing to note is also the side space available for the floorstanders. If the width is only 11.5' and then putting up 100" screen will almost leave no space for the front speakers.

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.

want to ask where can i buy or surf the website to check out the harman kardon av receiver, thanks
