20% Cancellation fee on
made-to-order products.

If you decide to cancel your
made-to-order speaker for any reason,
it is unlikely that we could sell it to 
another customer at full selling price.
We will therefore charge a
cancellation fee of 20%
of the order price.

at our premises for you to listen
