Plus One Engineering

NEWS!!

Due to the overwhelming demand for the SD4370 siren driver, Plus One Engineering regrets that we have had to suspend production of our professional line of loudspeaker components. We have been continuing to work on new product designs as time allows and we hope to have the opportunity to release some very interesting new professional speakers in the future.

Plus One Engineering is proud to announce the addition of a new product. The SD4370 high power siren driver is available in OEM/integrator quantities. This new design is approximately twice the efficiency of competing products thanks to modern magnetic materials, computer optimization and the expertise of the Plus One engineering staff.

Plus One Engineering is proud to announce our first distributor in Europe. Shermann Audio UK is now stocking replacement diaphragms. Shermann Audio is a well respected builder of loudspeaker systems in Wales, UK.

Replacement parts for Plus One Engineering and Emilar brand loudspeakers are available.

Diaphragms for 300, 320 and 175 series drivers are in stock at our distributor, Orange County Speaker.
