In addition to our regular repair services, we can remagnetize alnico magnets returning them to original factory specifications.

We build superb, faithful reproductions of the JBL 2231A, using recharged JBL alnico magnets.

We can repair split or broken ceramic ferrite magnets. This unusual problem primarily effects Yamaha, Eminence, RCF and Mackie speakers. Our structural repairs return these 'write-offs' to 100% original performance

If you have older speakers that you no longer want, that perhaps need rennovation or repair, we may be able to repair and recycle them, but please phone us first.

Our acoustics lab provides confidential engineering services for speaker developers, such as locating and qualifying driver and parts manufacturers. The lab is equipped for acoustic measurements of frequency response, distortion, power handling, dispersion, time domain (waterfall) response and dynamic compression. We also measure Thiele-Small parameters for 'pair matching' or to confirm the parameters after repairs or modifications

We have a massive knowledge-base in the area of enclosure design for sealed, vented, transmission line, active and passive filter alignments, aperiodic, passive radiators and bandpass systems, as well as horn system design.

We regularly design and supply passive crossovers, custom equalization and driver protection networks for custom speaker projects, in (modest) production quantities. Accurate reverse-iterative modelling for networks up to 36dB per octave

We appreciate wonderful music, and try to avoid frauds and charletans, so we follow this wonderful advice from Peter Aczel. This link opens a PDF file)
