Thanks for the reply guys,
Sorry, I should have been more clear. The $1000 budget is for the speakers (main) I'd like to spend no more than $3000, give or take, for the whole 5.1 sound system including receiver. I don't mind leaving out the rears for now to get something I can grow into if that's a better way to go. I was mistaken on the RX-V575. May have to look for another model that I can grow with.
I was thinking roughly -
~$1000 for the mains
~$500 for the center
~$600 for the sub
~$600-700 for the reciever
~$3-400 for the rears
... or however it should be broken down.
The room sounds huge when I say it like that, but it is reclaimed attic space and the total square footage I stated includes a bathroom and closet (so we can subtract ~100sq/ft). Also, the ceiling goes from 9.5' to 6' at the sides, so the room feels smaller than one with average 8' ceiling ht.
I know that what I'm trying to do isn't ideal, but I'm trying to make the space as multifunctional as I can. I just don't have another place in the house for a theater... rest of the house is quite small. This is not only my office/studio but will be somewhere my wife and I can watch movies. When I'm working or relaxing from here, I'd like to be able to have the mains set up to provide great sound in my seating area and decent 5.1 HT experience for movie nights. I have an SVS SB12-NSD downstairs in the living room and was thinking of adding another up here... Been pretty happy with the performance of that little sub. I'd like to go bigger, but as you mentioned, they get quite expensive. I think I might add another small sub down the road to get more oomph if need be. We typically don't listen at reference levels anymore, but do tend to crank it up some times.
Hope this helps to make things as clear as mud
I sure appreciate your efforts!
