The Otop DIY Speakers are the easy to build high output models of Bill Fitzmaurice Designs

• The OT12 may be built with a single compression driver on a CD horn,
  or it may be built with a six element vertical tweeter array for
  line-array stacking of multiple cabs.
• The OT12 may also be built with a twelve element cross-firing melded tweeter array,
  giving high frequency dispersion that no commercial PA top can match.
• For the highest possible output at the longest throws, build yours with a premium compression driver on a line arrayable full cabinet height horn.
• Also available in a J array trapezoid cab. The same kits fit both tradtional and trapezoid
• One of our most popular kits
