  2. KSN 1142A Initial Impressions 5 Star Review

    Posted by on 30th Sep 2017

    I received two Piezo Source KSN 1142A tweeters recently. Initial testing has comprised connecting them to a Sony XM-754HX car battery powered audio amplifier in bridged mode. I have fed it sweeping frequency signals up to 15 kHz and 25 kHz ultrasound tone bursts. For the ultrasound tones, I viewed the recorded acoustic outputs on a PC; obviously I couldn't hear them. The recorded ultrasound waveforms had a generally similar appearance to those of the feed signals. All seems pretty good to me. I'm satisfied and happy with the price.

  3. Excellent Customer Service from Piezo Source! 4 Star Review

    This is a very good quality horn driver at a moderate price.

  4. Excellent Customer Service from Piezo Source 4 Star Review

    Posted by on 6th Jan 2016

    I gave a 4 just because the connectors were bended due to poor packaging , but other than that after I installed and tested them, they sounded perfect.

    Very professional customer services.

  5. Very Satisfied with my purchase 5 Star Review

    Posted by on 13th Feb 2014

    I had a PA system that had a defective tweeter, which was an original Motorola Powerline series model. I turned to Piezo Source who delivered to me excellent services and the replacement speaker worked fine.

    I highly recommend this company for anything in their product line.
