SVS Ultra Bookshelf Upgrade Kit (Pair)
The price is per pair! The price of Sonicaps have just gone up and it caused a slight increase in the cost of this upgrade. This kit includes everything you need to correct a number of issues and take this speaker to another level across the board. Please see the videos and measurements in the accordion below. The kit includes all new parts, a set of tube connectors and new wiring.

Take a look at the before and after measurements. With the modification kit, there is no question that you will not only end up with a subjectively better sounding speaker, but the measurements back it up as well!
