I finished up my 7.2 home theatre with 2 x SB4000 subs which integrated seamlessly. The subs produce bass notes I have not heard before so I am currently going through all my music and movies to see what I missed. Overall, I could not be happier! Thanks to Aamir and Summit Hifi for making all of this happen.
Looking to add the second SVS SB4000 to my HT setup. This subwoofer is amazing for both music and movies.
Aamir was amazing. Just waiting for them to break in. Top notch service and follow through. He is the only guy to deal with.
Top notch service!!
This thing pounds with anything you throw at it, Metal, hip hop, rap, electronic, hard rock, it's an absolute beast. Movies, no doubt the best sub I've heard. Movies like Dredd and Mad Max Fury Road play frequencies you can't really hear but FEEL in your chair and it is an amazing experience. Talk to Aamir, he set me up with this sub and I cannot be happier with my purchase.
