*BUMP* (one and only time)

If you want a good sealed 12 inch subwoofer, the SVS SB12 Plus can almost surely equal or better the vienna for less money.

IMHO, there is nothing special about the vienna except its shape and appearance.

If you are an audiophile, the Velodyne DD-12, or DD-15 would be a much better choice than the vienna, however, the SVS SB-12 Plus will probably meet your needs. Better yet, a pair of SB-12 Plus' would be enough to hold you for a long time.
