For the ported line-up:

In response to market demand, the dual-driver ported subwoofers have a lower 13Hz tuning.

Available with Eminence and LaVoce drivers. High-excursion, high-power handling, tour grade drivers ensure a strong low-end, without sacrificing mid-bass punch!

Available as flat packs - the same panels used to create our flagship line are available to the DIY enthusiast!

Triple-layer baffle, with mega-chamfers, pre-drilled for driver mounting inserts (inserts and bolts included) and dowel pin construction.

Dual Speakon mounts on rear of cab (one Speakon per driver or parallel wire both drivers to a single Speakon, providing a wide range of connectivity options between drivers and amplifiers).

Grills are available for a completely finished, commercial look.

Detailed assembly instructions are available here.
