mwkUltra 4x12 guitar speaker cabinet

The mwkUltra is a collaborative design between mwk Audio Design and KSR Amps. Michael and Kyle worked together to develop a truly unique cabinet that would perfectly compliment the SPD100 amplifier.

It is similar in construction to the KSR RCS/412, although features different internal bracing and rear panel. It also features a custom machined grille in durable matte black and is covered in carbon fiber tolex. In addition, it uses recessed metal side handles and high-quality removable casters.

This cabinet is equipped stock with Celestion G12H-150 Redbacks/G12H-75 Creambacks in an X-configuration. It also employs a Plug’N’Play jack allowing 4 Ohm or 16 Ohm mono @300W, or 8 Ohm stereo with each side @150W.

Dimensions are 31” H x 31” W x 14”D, and shipping weight is approximately 115lbs.

All mwkUltra 4x12s will be built to order. Construction is already underway, but please allow 1-2 months for completion.

Shipping will be billed at the time of completion.
