- Dedicated 21 X 17 space on third floor - Current condition - under construction
- Preferred budget - 20L but can extend to 25L in staged manner
- Looking for Dolby Atmos setup - 7.1.2 or 7.1.4 (not sure how much 7.1.4 differs on 7.1.2)
- Currently in US but setup in India, so can source goods from US but prefer to buy in India/Singapore
Pls suggest/advice on how/what I can plan on my budget
- How much of my budget should i spend on speakers/acoustics/seating/wiring
- How do I select speakers for room size
- Suggest speakers/Amp combinations
For 20 L to 25 lakhs budget , you can do professional home cinema installation which is done by dealers. You can go to them look at their demo setup and decide. This will simplify the process and they will have best matched components & they will do complete installation including screen , speaker setup , Room Acoustics treatment , HT room decoration , light setup ..etc.
In bangalore "Tasmai automation" deals with high end HT setup which costs more than 20 lakhs - they have showwroom in jeya nagar. I am not sure they have it at your place.
We often choose the components ourself as we are strict on budget

If you have to choose the components.
Go with ultra HD projector ( Sony /compaq ) - they have high end models ranging from 5 to 8 lakhs.
Choose high end AVR which may cost (2 to 2.5 lakhs) (drawbback with AVR is - they have limitted power to handle speakers.)
better
Go with dedicated AV processor ( may cost around 1 to 1.5 lakhs)
And power amplifier (with 300 watts rms out , 7.1 channel) - Emotiva have some model. (which may cost 2 to 2.5 lakhs)
Speakers - you have lot of options
Personaly i liked sonus faber Floorstanding speakers - beautiful sound (which may cost 3 lakhs)
And Sonus faber Center , surround speakers ( around 2 lakhs)
Go with 2 numbers of 12 "sub ( cost around 1.5 to 2 lakhs)
Spend some good amount on screen - max 1 lakh (going beyond may be waste of money )
Spend rest of the amount on room acoustics / room setup.
- Currently in US but setup in India, so can source goods from US but prefer to buy in India/Singapore
US will be cheaper .. You can source a good AVR /or AV processor. But you need to pay custom duty of 30% (i think) , you may show it as used one and may bargain to indian customs. Still it will be cheaper than buying from indis.
Warranty will be mostly void & most company rejects service in india if its sourced from foreign. (Onkyo clearly displays the message from their indian official website)
