Another thing to consider is your room setup. Are you going to have a dedicated room for your mini cinema? Or are you putting in your living hall?

You also need to set a budget. As ronnt88 mentioned, 40k to 50k will get you a very nice setup. But if you don't want to spend so much, I think 20k to 30k can also suffice. The main thing that will eat your budget is the projector and screen.

Wah, your standard so high one? In that case I fall into the 'indecent' category...

Heh, you're special. Not only indecent but horny some more...

Wow, you mean the sound proofing material is 6" thick? What kind of material is it?

I agree, the PQ and AQ in local cinemas is not up to standard. Watching in a properly setup home theater is better!

When you say "standard projector" you mean those used by companies to show presentations?

For one, HT projectors have higher resolution (especially full HD type, 1920x1080). HT projectors are also more geared towards black levels and color accuracy, because these are important for HT use.
