Vandersteen 5A Speakers

One owner custom color/finish on walnut 5A's from 2007. These were used in both 2channel and 5.1 theater configuration with high end amplification from Pass Labs. Balanced connections only to outboard filter/crossovers. Your amplifier is used to power the high pass section of the speaker only with an internal amplifier handling the bottom which makes these very versatile and easier to drive than one might otherwise think. Many adjustments available to fine tune these to any room. Never moved until now back into the original cartons and palettes. Overall fine condition with only a few spots where the grill fabric is wearing. Amazing speakers, especially at this price point.

$4,600 plus shipping. Local pick-up preferred

Also available to be added if a theater set-up is preferred are the VCC-5 center channel speakers, and a pair of VSM rear channel speakers.
