GR-Research began in 1995 as a passion for high quality audio turned business venture. We are driven by a desire for excellence and expect nothing less than to turn the next page in mainstream loudspeaker design. We offer many high quality loudspeakers in kit form. We have high quality crossover components and accessories for any project. We have our own proprietary line of drivers that are used in our designs. We also provide a wide range of design services from complete commercial product line design to assistance with individual custom products and upgrades.
UPDATE 12/04/21:
We are currently dealing with the ongoing global parts shortages and shipping delays.
Tube connectors for all kits are expected to arrive by December 7th.
Rythmik is currently out-of-stock on all A370 PEQ Servo Amps, and subwoofer kits will be unavailable until their next shipment.
Thank you for your patience!
