It has two modes on its back..movie and music..music mode makes its lower extension somewhat limited, making it closer to sealed sub like experience..though my sub setup is far from ideal due to space issue at my current apartement..thats why i am experiementing with diff mode and phase setting along with variable crossover.. yet to settle at a particular setting.. its difficult to combine sub with an amp, much easier with avr and its lfe settings.. so, you have to search for the sweet spot, but i guess you will like its performance for music too..i am using it mostly for music (90:10) and i am enjoying it throughly.. you will hardly get anything better at this price range in india ..check whathifi review..also, in USA (amazon.com) it is priced at 500 usd, same as svs pb1000 and more than sb1000..
