Omni 10.5 Crossfire Cabs
Loaded with Eminence Beta 10 drivers
These remarkably lightweight and efficient devices are the brainchild of American cab designer Bill Fitzmaurice - "BFM" for short.
The "Crossfire" designation comes from the rows of HF horns, set at 90° so that they fire across each other to widen dispersion.
Bill designs many different types of speaker enclosure, but he doesn't sell the cabs.
Instead, for a mere few dollars, he supplies detailed, fully illustrated construction plans, so you can build them yourself - or get a professional cabinet maker to do all the clever stuff for you.
Mine were built for me by the UK's first authorised commercial builder of BFM designs, Steve Torrie.
