Read what some of the leading reviewers said about some of David’s designs!

the amount of low bass energy this speaker can produce is astounding..

is up there with the established big boys, ATC, Genelec, PMC and the rest..

Hugh Robjohns optional, I would suggest imperative extra is on site analysis and alignment of the system..

the results were most impressive, exhibiting delicacy and presence conveying the subtle detail..that few boxed loudspeakers can equal

Although plots and graphs won’t tell you exactly how a loudspeaker sounds they are a guide to the performance capability.


Measurements were taken with a calibrated Behringer ECM8000 microphone which was placed a few millimetres from the baffle. Both gated and pink noise results were taken and the graphs created by the ARTA software programme.


EQ is applied in the digital domain (Behringer 2496 Ultracurve). For dipole, the rear cabinet would be reverse polarity. Also reverse polarity for a cardioid, super or hyper cardioid response but DSP is required to enable delay to be set to the rear woofer. (See photo of Wide Boys back to back on their page..2 cabinets required!)
