Drivers has arrived



(QC) Quality Control of Driver & Crossover


All Loudspeaker Drivers I sell are Quality control checked mechanically for cone alignments and compliance,


The  driver is then  swept with a sine wave  from 10Hz to 40Khz Using the  LMS “ Loudspeaker Analyzer “  for impedance, level,  voice coil aberrations (noise) and phase pulse test .(phasing error)


 If the drivers are part of a  STONES Speaker Kit then the Crossover unit & internal wiring plus speaker terminals are included in the QC testing to ensure that You receive a quality speaker Kit, that when installed works and provides excellent sound quality the first time.  Speaker Kits are supplied

In matched pairs with Left & Right Speaker, marked on the Drivers and Crossover units. The Stones level 3 upgrade Kits crossovers *and drivers are hand tuned and listen to in an evaluation enclosure before shipment. 

If the Loudspeaker Drivers do not pass QC testing then they are not sold .
