JAM Systems Flex 15 Speaker Cabinet Flatpack Kit

The Flex15 flatpack kit has been designed to take the hassle out of building simple, versatile, high quality speaker cabinets. This is a general purpose cabinet that can either be used as a mid-high or a full range speaker, and can be fully customised to precisely suit your needs.

To maximise versatility we have designed the cabinet around the P-Audio SC series of Horn Flares, there are currently five in the range:

1" Horn Flare Options: SC-1064 1" 60 x 40 or SC-1096 1" 90 x 60
1.4" Horn Flare Options: SC-1464 1.4" 60 x 40 or SC-1496 1.4" 90 x 60
2" Horn Flare : SC-2064 2" 60 x 40

All five horn flares have the same panel cut-out and will fit in this design, and all five horn flares are rotatable, so you can choose from 40 x 60, 60 x 40, 90 x 60 or 60 x 90 for 1", 1.4" or 2" exit throat compression drivers, depending on application. With a choice of throat sizes, there is a solution for just about everything.

Pack includes:

1 x Front baffle precut for typical 15" mid-bass woofer and SC series horn flare. 2 x side panels, with mitred angles and CNC cutouts and recesses for 3402 steel bar handles.
1 x Rear panel with mitred angled edges. Precut with recess for 87160 angled connector dish.
1 x Top Panel with curved front edge for continuous curve when stacking multiple panels
1 x Bottom Panel with curved front edge.
1 x Internal Middle brace
1 x Combinatation Port/Grille Support
2 x Curved grille supports. 1 has no cutouts, this fits the top of the speaker, the second (optional) has a recess on the back so it can sit over the front gasket of the 15" woofer.
3 x Port Braces for added strength
4 x Grille battens
The front panel is cut from high quality 18mm birch ply, and the other panels are 15mm high quality birch ply.
