Extension Cabinets

Great looking, great sounding cabs & you can tune your bass response, too!

Note: This page is still under construction. I know, it shouldn't be up until it's totally finished, but we've been getting a lot of inquires about our new extension cabinets and we wanted the pictures available before the LA AMP Show.

Southbay Ampworks Extension Cabinets

2x12 "adjustable" back extension cabinet:

  • Slanted front baffle board aims the speakers up towards the player.
  • Pine or baltic birch cabinet sides, 1/2" baltic birch front and back panels.
  • Adjustable back design, allows the player to adjust the back pressure to alter bass response for the speakers used or to tailor his tone for the amp & guitar used. This makes getting "your tone" a lot easier in a club or recording situation.
  • The top half of the back panel is mounted on a piano hinge which allows it to be opened and is full cab width for stability. The same panel also has a sliding lid hinge which allows the player to set the panel from 1/8" open to full to adjust for bass response, back pressure, "air", and tailor the tone to taste.
  • The adjustable back feature allows you to have a closed back, partially open back, or completely open back cabinet without buying different back panels, or using any tools to convert from one mode to another!
  • Available in tweed, smooth black levant, or black elephant tolex coverings.
  • Black, Basketweave (S&P), Oxblood or Bluesbreaker style grill cloth, with white or gold piping.
  • Silver or gold handles standard, side metal handles optional.
  • Large rubber feet for solid bass response and durability.

29.5" Wide, 20" Height, 11.5" Deep
Weight: Pine cab 21 lbs (unloaded) 39 lbs (loaded with Scumbacks).
