Tuba 45 12" DIY Folded Horn Subwoofers

by Bill Fitzmaurice Designs

When it comes to earth-shaking gut-wrenching low-down bass there's
no substitute for a folded horn.

Tuba Subs take advantage of proprietary folding topology to squeeze
the most performance possible from small woofers, and that translates
into huge bass from small cabinets,with high efficiency

  • The T45 is an oblong version of the T30.
  • The design is ‘end firing’, so it may be placed laid down, or stood up on end where floor space is tight
