I'd been meaning to try out some pipe organ music on my SVS 16PC-46 for some time to see what would happen and what ungodly lows might be present. This became a particular goal after doing the driver upgrade recently. Finally got around to it the other night, and tried Bach Complete Organ Works vol. 1 played by Ton Koopman on Telarc. Whoa! Butter smooth, all the way down to gut-punching. Effortless, no straining despite my constantly bracing myself for something to creak or give at high output levels. Even if you're not necessarily a Bach fan, if you have an SVS 16-46 it's worth a trip to the library to get one of these CDs and see what really musical lows can sound like. Fun!
