We no longer offer individual amplifier or driver in order to focus our effort on servo products.

International orders (CI kits only)-- from US

For international kit shipping from US, we use the US postal service exclusively with shipping cost shown in the shopping cart when selecting postal shipping option. This is a cost effective option.Again, we encourage you to consider the reliability of postal service on your end as this is beyond our control. We would like the transaction to be as trouble free as possible, so that you can enjoy your subwoofer as soon as possible.

For completed subwoofers, the most affordable shipping methods is via DB Schenker and UPS.


Please ensure the power selection is set to the appropriate mains power supply voltage for your country. All orders are shipped with 110-120v as the default selector position. Failure to select the correct voltage could result in amplifier failure, and this is not covered under warranty.

Warranty and Return Policy in US for Complete Subwoofers

At Rythmik Audio, we stand behind our products. Our return policy is as follows:

  • Warranty is 3 years on electronics and 5 years on drivers.
  • All returns need a RMA number. Please contact us before you return the product.
  • Complete subwoofers can be returned within 45 days after you receive the unit. In case of return, customers only pay for return shipping.
  • All of our shipments are insured. For damaged shipment, please notify the appropriate postal service immediately.
  • All products carry warranty against defects as specified in the product information web page.
  • Products needing service under warranty should be sent to us insured at your cost. We will either send a new unit or repair the returned unit, at our discretion.
  • All other returns of non-defective units are subject to a restocking fee.

International Warranty and Pricing

International warranty is via the distributor in the region. We encourage customers to buy from distributors in order to receive best service. The pricing from the distributor can be higher than US price mainly because the cost of conducting business (such as in import duty and overhead) is different in each country.

Please note:

The warranty does not cover abuse, nor incorrect installation. If you are unsure about any aspect of installation, please contact us rather than risk making an expensive mistake. Abuse includes continuously playing sine wave and other test tones for an extended period. A duty cycle greater than 25% is considered abuse, where the test tone plays for 15 seconds followed by a break of 45 seconds. Abuse also includes, but is not limited to, running the sub in such a way that the excursion limits of the driver are exceeded, or the thermal limits of the driver or amplifier are tested by continuous use for an extended period at high output.
