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.

S/S Classic 13M 8640 Diameter:130mm

Paper Cone Midrange

A classic Scanspeak midrange, producing a rich, natural full-bodied sound, which is detailed and clean. The impregnated cone is hand coated with a special material to achieve high resolution, better reproduction and dynamic linearity. 

The 13M 8640 is built onto a heavy diecast magnesium chassis to ensure stability and low resonance.

Ideal for use in any high quality 3-way systems and our recommended upgrade to the KEF B110, or for replacing other midrange units, where natural, smooth and high quality sound reproduction is required.
