KICKSTARTER IS COMPLETE! We are in production! More to come soon!


The Subwoofer is fully compatible with all versions of the JRA Speakers. The included RCA to 3.5mm cable is used to connect the Subwoofer to the 3.5mm input on the back of your original amplifier. The new version 3 amplifier connects to the subwoofer using the included RCA to RCA cables.

Most record players require a phono pre-amp to connect to your JRA Speaker System. You would first connect the turntable to the pre-amp’s input, then the pre-amp’s output to your JRA Speaker System’s input.

Any part of the system that is damaged during shipping or does not work upon arrival will be replaced immediately, free of charge.

We offer a one year limited warranty. If you have any issues with your product please email us at

The system is compatible with 110v to 240v power mains, which covers every country in the world. The only adapter you will need is the simple, inexpensive type that converts the shape of the US plug to your country’s standard outlet. A voltage converter will not be necessary.
