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 / sonically brilliant but fatally flawed due to gas loss and barometric pressure changes, many are now defunct with low or no output. Full details of this tweeter can be found by clicking the link below:

HD-3P datasheet

We offer a replacement kit for the HD-3P featuring either the Scanspeak D2905-9500 or D2904-9500 tweeter and custom built crossovers; each crossover / tweeter combination is matched and aligned to the specific application. You will need to remove the HD-3P crossover / transformer; the Scanspeak tweeters are supplied fitted with a unique 100mm faceplate and are a drop in fit, no carpentry required.

Supplied as singles or pairs, please make your selection at the top of the page. We hand build the crossovers to order, please allow a lead time of 7 working days.
