Quad repairs, B&W Repairs

For those with damaged or not working Quad ESL’s, B&W DM 70, Final 0.3 / NSS hybrids or Martin Logan ESL’s, who are prepared to put in a few hours work to bring their speakers performance back to as new

These kits provide sufficient materials to re-diaphragm a pair of Quad 63’s, Quad 57’s, Final 0.3’s (Newton Sound Systems) or B&W Dm 70’s. The kits contain genuine Dupont Mylar C diaphragm material, conductive coating, applicator, tension scale, adhesives, foil tape for EHT rail repairs, EHT wire etc, and yes, there is enough material in the kits to do the repair a few times should you make a mistake.

The 3.5 micron film supplied in the kit also makes an excellent lightweight material for Quad 63 and 57 dust-covers, giving improved transient response.

Martin Logan ESL’s

The older Martin Logan ESL’s have now reached an age where they start to lose sensitivity, sometimes leading to complete loss of output on one or both ESL panels. On hybrid designs, this causes an imbalance between bass and treble, making the speaker sound bass heavy.

While we do not provide full repair kits we have assisted many Martin Logan owners economically bring their speakers back to life with a few simple components such as conductive coating, foil tape etc.

We can provide the necessary repair items and guidelines in the form of written instructions and drawings on the best way to carry out this repair.
