Magnepan LRS Upgrade Kit (Pair)

$259.00 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.
