I m using svs pb1000 and I have tested in my living room which is 22x22 , it just filled my room . I kept 70 percent of volume at -4 db .Best suits for movies and for music its not wow ,but above average. Give a try .
Assuming it's an AVR, you should use the "pure direct" or similar mode for music. In which case the sub goes out of the equation. Even otherwise, I don't think you really need a sub for music with your speakers.
In your budget and specs, only the SVS would fit. You can get some auditions in Bangalore.
