A Parabla Cab

PARABOLIC LOUDSPEAKERS

“In the early 1960s the BBC were undoubtedly ahead of the game in studio sound engineering. The original theme tune to the first Dr Who television series was proof of that – involving advanced groundbreaking studio effects engineered by the BBC Radiophonic Workshop. The BBC also produced a technical reference manual called BBC Engineering that was available to everybody. One of their reference speakers used the idea of cabinet curvature to project sound – the BBC called it a PARABOLIC loudspeaker cabinet, which had just one speaker. As with many things in sound engineering, what worked in the studio did not necessarily work for the guitar. But we took the BBC’s basic idea and developed it for bass guitar. As they called it PARABOLIC, we came up with the name PARABLA. Later on, we simply called it the 2×15 REFLEX cab. Always trying to improve our own studio monitors in the Orange Studio taught us a lot about loudspeakers and cabinets, which was very useful when it came to us designing something completely new.”

2×15″ REFLEX BASS CABINET

“It was our idea to have two 15” speakers, one on top of the other moving in opposite directions. What that did was damp the cones so you could get a lot more out of it before the cones started ‘pushing’. With the first prototypes, we initially created the internal curvature by bending a single sheet of thin plywood, but at high volume it tended to rattle. In the end, and after some trial and error, we used six layers of 3mm plywood which – which was more flexible – glued together. In those early days speaker manufacturers like Celestion, Fane, and Electro-Voice were aware of technology moving on. As amps got more and more powerful, speaker manufacturers had to keep up. We just felt that our 2×15 speaker design was far superior in sound to anything else that had two speakers facing forward. Bass players were amazed at the sound projection – the Reflex was well ahead of its time. We mainly used Celestion or Fane, but we did offer a deluxe version of the reflex with Electro-Voice speakers. 1×15” Bouncer Bass The Reflex 2×15 sold so well that we developed the Bouncer bass cabinet, which had just one single 15” speaker and was smaller and more portable. It was a folded horn design cab. We also made a full range model with mid range and high frequency horns, which doubled for PA or Disco turntable music. We considered re-introducing the Reflex cabinet again, but they are not, at present, cost effective to produce.”
