2″ x 8.5″ Flared Port

2″ dia x 8.5″ long flared port

This is a 2 piece port system featuring a 2″ dia. flared port end and 8″ long, cardboard tube.  The flare end is 1″ long so  tube combined with the flare equals a port 9″ long.  You can easily cut the tube to length to conform to your design.

We use this in the Mandolin, Kairos, and Aldelphos kits.

You can buy a separate flare end and create a tube that has flares on both ends.

• 2″ dia abs plastic, inner flare end (Plastic flare adds 1/2″ to the length)
• 8″ long cardboard tube – can be cut to length.
• Inside can be painted black
• Buy an additional flare end for a double flared port.
• 79mm (3-3/32″) outer flare dia.
• 73mm  (2-27/32″) cut out

The only drawback for this nice port system is the small mounting flange dia. about 1/8″.  The ability to make a precise hole is mandatory.

Please not that is using a second flare on the inside end of the tube, it must be attached after the outer portion is glued to the cabinet – usually through the woofer hole.
