From Mesa Boogie:
The 2×12 Lone Star® Cabinet emphasizes punch and projection combined with vintage warmth while still maintaining a portable footprint and the classic styling of the Lone Star line. This open-back 2×12 utilizes rear-loaded speakers for a perfect marriage of punch, vintage mid-scoop & sparkling top-end. A true vintage voice that’s sure to shake your memory while reshaping your idea of great tone.
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 and 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.
