While the 310px is very rugged in use, some aspects of its design require careful handling
during installation. In particular, the voice coil is vented below the spider. This improves
power handling and linearity, but it also provides a path for particles to become lodged in
the voice coil.
• Keep the 310px in its protective plastic bag until you are ready to install it.
• Keep the unit away from sawdust and metal shavings.
• Thoroughly vacuum the inside of the enclosure before installing the woofer to
remove any sawdust or wood shavings.
• If using fiberglass or polyester filling in the enclosure, completely cover the rear of the
driver with a piece of cloth between the driver and the filling.
• Do not use wood screws to mount the woofer to the cabinet. Use "T"-nuts and
machine screws only.
• Do not press the dustcap! This will cause permanent deformation.
• Be careful handling the speaker frame to avoid scratching the cosmetic surface.
The 310px is unusually heavy and has very high capability. It demands above average enclo-
sure construction to perform at its best. We recommend that you construct the enclosure from
MDF or laminated Baltic birch plywood at least 3/4" (20mm) thick. Whenever possible, 1"
(25mm) thick material is preferred. Due to the unusual beauty of the 310px frame, you may
want to show it off with one or more panels made from clear acrylic. All acrylic panels should
be at least 1" thick. Use "T"-nuts and machine screws to fasten the 310px to the enclosure.
Make certain all of the joints and panels in the enclosure are airtight and rattle-free. Seal any
terminals or wire access holes completely. Seal the driver's mounting surface with foam tape.
Some applications may demand a different solution than the above recommendations allow.
For example, you may need to construct an enclosure from Fiberglass, Kevlar, or Carbon Fiber
in order to fit into an irregularly shaped cavity. When using these materials, try to keep any
unsupported flat wall surfaces to a minimum. Add bracing whenever necessary to keep the
enclosure walls from flexing under pressure.
