Special Order

Open- and Closed-back Performance from One Cab!

The Mesa/Boogie 4 x 12" Road King Straight Cabinet helps you make the most out of your guitar rig's sound while providing unprecedented tonal flexibility. Using Mesa's Dual Cabinet design, the 4 x 12" Road King Straight Cabinet lets you choose between an open-back (left) and closed-back (right) side - or you can combine both sides for a stellar-sounding blend. It's wired for mono or stereo operation, giving you maximum flexibility. It's also made to work perfectly with the Road King amp's cabinet switcher. Able to handle up to 300 watts, the road-ready 4 x 12" Road King Straight Cabinet is built to take whatever you dish out.

Mesa/Boogie 4 x 12" Road King Straight Cabinet at a Glance:
  • Two cabs in one
  • Two different speaker configurations
  • The best of both worlds
Two cabs in one

Perfectly matched to the built-in cabinet switcher found on Mesa/Boogie's landmark Road King Amplifier, Road King cabinets provide a new level of performance and convenience through the use of a new and innovative Dual Cabinet design. This new design features both a tuned open-back side and a sealed closed-back side, each of which may be used independently or combined.

Two different speaker configurations

Loaded with two 12" C90 speakers on the open-back side, the 4 x 12" Road King Straight Cabinet gives you the detailed clean tones you crave, while two 12" V30 speakers sit in the sealed section. Used independently, the two sides function as different cabinets with different tonalities - a very handy setup! Combine the two sides and you've got a 4 x 12" cab that offers the best of both worlds from one package.

The best of both worlds

Want dimensional, shimmering cleans that envelope the stage? How about tight, focused lows that seem to leap out of the cabinet? The 4 x 12" Road King Cabinet gives you both! Clean tones and lower gain textures shimmer and sparkle with beauty from the added spaciousness and presence of the Road King Cabinet's tuned open back. Medium- to high-gain tones pack maximum authoritative power and punch when driven through the King's sealed closed-back side.
