Quick Start Guide

My Sub arrived with a faulty driver..... I am posting my review one year later.

Yes, the people at SVS were very helpful but the distributor in Canada lacked the knowledge that a Driver Removal Kit should have also been sent to me with the replacement driver. It only took 2 people 3 hours to struggle, tug, pull and yank the drive out of its tight, very tight enclosure. I have to cut a hole into the woofer cone in order to pull the driver out but that was the easy part. Trying to wedge the new driver into a hole 1 mm smaller than the driver size was a nightmare. I only made one 1/4 inch scratch that I fixed with a black sharpy pen. The new driver works flawlessly and I really enjoy the pair of SB4000 for my home theatre and music room.

Excellent sub

I have been enjoying my SVS SB-4000 sub for a couple weeks and I am thrilled with it. Not only is it beautiful to look at but it sounds great having integrated perfectly with my music only system. Setup was easy with the app and making little adjustments is a breeze.

As always I am totally happy with the service I received from Summit Hi-Fi. I have purchased from Aamir in the past and will most certainly purchase from him in the future. I'm already thinking about adding a second one.

Dual SB4000 subs

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.
