Our Most Popular 4x12 Cabinet and an Icon in Heavy Music
When it comes to 4x12 cabinets, we offer a choice of two distinct and different sounding/sized quad boxes: our legendary oversized Rectifier® Standard and Traditional Cabinets.
The Standard Rectifier® 4x12 is THE “oversized” 4x12 by which other quad-box cabinets are judged. It was designed to be the perfect companion to the high gain revolution created by the Dual and Triple Rectifiers®, providing thundering low-end punch and resonance which is perfectly tuned with the smooth, tailored midrange and articulate, clear high-end. This is our most popular 4x12 cabinet and an icon in heavy music, used on more hit recordings than we could list here. MASSIVE SOUND!
Slant-style Recto 4x12 Cabinets offer a ‘monitor’ effect due to the top speakers sloping up toward your ears. This can be a benefit when playing live. Other players prefer the STRAIGHT-style cabinets with all speakers attached to a one-piece baffle and all facing the same direction, effectively ‘coupled’ for maximum punch and frontal projection. Regardless of Slant or Straight, if you are playing a Recto 4x12, your tone has authority, clarity and detail that only MESA® Traditional or Standard 4x12 Rectifier Cabinets deliver.
You simply won’t find a better cabinet. ALL MESA® ENCLOSURES are made using the finest Void-free, Marine Grade Baltic Birch. Super strong rabbet corners are glued and nailed. Speaker baffles are fitted with superior dado joint construction and braced. Grilles are wrapped around a separate grille board, not the baffle board. Grille material is made of strong twisted jute dipped in a special coating that filters top end for a sweeter response.
