Drivers has arrived
STONES SOUND STUDIO
(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 .
