Electro-Voice ASP-1 Adjustable Mounting Pole for Select Speakers and Subwoofers

The Electro Voice ASP-1 is an accessory pole that attaches to the top of the SB122 bass module, allowing the addition of a small full range speaker such as the Zx1 or Sx80 for a more complete system. It can be adjusted for height from 36 to 60" so that you can position it right where you need it.
