Monacor SPM-205 Bass / Mid speaker


8 inch woofer - steel pincushion chassis.

Excellent value replacement for 8 inch bass units with the 'pincushion' pressed steel chassis i.e. KEF B200, Dalesford D50/200, Mordaunt Short DSB208 and many Elac (UK) drive units.

Kef, Monitor Audio, Wharfedale and many other manufacturers used this style of chassis in the 1970/80s

Some small adjustments may be necessary as the profiles tend to differ slightly across the brands.

These are a very cost effective way to revive many old classic speakers.

Available in 4 and 8 ohms - select using buttons above.
