All Audax drive units now listed

New old stock drive units from Audax.

Audax were true innovators and released many cutting edge technologies never seen before such as the HDA (High Definition Aerogel) cone - a unique product based on acrylic polymer gel containing carbon and kevlar fibres in perfect molecular alignment. HDA was the product of extensive research for the perfect cone material that is both lightweight, rigid and displays high internal damping. Another breakthrough technology was the brilliant but sadly short lived 'gold eye' HD-3P: the  Audax HD-3P  tweeter was a piece of exotic, visionary engineering from the 1990s. Fundamentally a piezo tweeter, it featured a gold spattered elliptical diaphragm formed onto a nitrogen filled balloon. Technically and sonically brilliant but fatally flawed due to gas loss and barometric pressure changes; many are now defunct with low / no output or exhibit the 'crinkle of doom'. We supply a replacement kit for the HD-3P here:  Audax HD-3P replacement kit.

Mission 753 Crossover Rebuilds

July 20, 2018

Mission 753 Crossover Rebuilds.

We now offer a crossover rebuild service for the ever popular Mission 753 floorstanding loudspeaker.

Rather than using specific crossover capacitors, the 753 featured standard aluminium electrolytics wired in series to form non-polarised electrolytics - this far from ideal cost / space saving excercise was part of the price to performance balance, and to be fair worked reasonably well but is now a prime candidate for upgrade.

Another potential problem with the 753 is the very high tweeter failure rate and subsequent crossover damage:

Melted inductor

The 753 often turns up on auction sites with dead tweeters - running these speakers with open circuit tweeters for extended periods of time causes the tweeter bypass inductors to heat up and melt; we supply a kit of components to cure this issue:
