Damping material

Damping material for one pair of Reference Compact or Ultra bass enclosures

When you are building our Reference Bass enclosure to complete your Oris system you'll need this specific damping material. The kit includes the pre-cut Tyrofoam sheets, BAF wadding and decent screws to mount the drive units.

Glue for the Tyrofoam is not included. For this you can use any kind of material as long as the whole surface of the sheets is covered. We normally use Bison Waterkit (a Dutch brand) but any other water based carpet glue will work just as well.

The price listed is excluding sales tax (i.e. VAT, Mwst., BTW) and shipping.
