SVSound is a relative newcomer to the home audio arena and has quickly made a name for itself. In the relatively short time they've been in existence they’ve earned an enviable reputation for building products that deliver exceptionally high value for the price. My experience with the PB12-Plus/2 has shown that reputation is richly deserved. This is one impressively big bang-for-the- buck product.
