Description:
You're bidding on a vintage pair of Pioneer Alnico PT-3K exponential horn tweeters (1960s) in outstanding condition. 16ohm voice coils and stamped on their backs at "20 watts" and "crossover 2.8KC". This shows their versatility, as they're often used as super-tweeters and filtered to kick-in at around the 7000Hz mark (you could add a potentiometer to manipulate this). Anodised gold alloy horns, beautifully cast, and boasting shielded AlNiCo magnets (extremely expensive to produce and impressively stable at high temperature to assist voice-coil accuracy). The horn itself has a 10cm x 4cm opening while the bracket immediately behind measures 12cm x 5cm. The whole assembly is 12cm from front to back of magnet and they're very weighty. Silky smooth response and particularly agile, these are classic, quality units and very difficult to find, especially in this, near-mint, order. I'll post Australia-wide for $15 and i'm happy to send oveseas but ignore calculator and contact me for a quote. Good luck!
