1x12's are the most popular size of guitar speaker and for good reason.  The 12" cone can deliver deep base tones, the 12" speakers have received the most design and development attention over the years and a 1x12 cabinet is still portable.

The cabinet itself is hand crafted from 13-ply baltic birch plywood - well established as the best material for speakers.  It features box joints for tremendous strength.

The speaker is the famous alnico Jensen P12N. You'll love the warm, full bodied tone and the sparkling highs. And it's colorful crunch when presented with a distorted tone is legenday. You can also substitue the lighter weight Jensen Tornado neodymium speaker if you'd like.  Listen to a comparison of speaker tones here.
