Hello, new member here hoping for a recommendation for somewhere in North London that could very accurately cut and rebate five holes for loudspeaker drivers in two sheets of 18mm or 25mm MDF. Examples of three of the cutouts are attached. The fourth speaker will be substantially similar to the third one below (T27) - i.e. less complex than either the B139 or the B110 and the final hole is an oblong measuring 3" x 10".
