Scanspeak 13M 8640 Classic

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.
