Interdyn P3 Floorstanding Loudspeakers Interdyn P3 Performance Series Loudspeakers. Sold by Encel Stereo in the 1990s. Made in Melbourne by Aranmar Acoustics using high quality Scandinavian SEAS drivers. Excellent condition. Please see the sales brochure in the photos for more information. Spec below: Design Principle: 3 way tuned port enclosure Woofer: SEAS 250mm Nitrile Surround, 4 layer voice coil, high gauss magnet Midrange: SEAS 100mm treated fibre cone Tweater: SEAS 19mm soft polymide done Frequency response: 40Hz - 20x000Hz Recommended Power: 30 - 100 Watts Sensitivity: 89 dB Nomina
At A$500, these Interdyn P3 floorstanders are ambitiously priced compared to the typical used market, where the median sits at A$378 and the 75th percentile reaches A$396. This asking price clearly exceeds the upper range of comparable listings, making it a tough sell unless the condition is pristine or includes rare accessories.
However, the P3 remains a worthwhile buy for enthusiasts seeking deep bass and clear mids, as they outperform many stand mounts like the Mission 760SE they replaced. Designed locally in Melbourne by Aranmar Acoustics with high-quality Scandinavian SEAS drivers, these speakers offer detailed soundstaging and fast response. If you are an original owner or can secure them at a fairer price, their local heritage and robust build make them a compelling opportunity for upgrading from smaller speakers.

Encel is an Australian hi-fi brand with roots in Melbourne, where Alex Encel first introduced the concept of the hi-fi stereo system to the Australian market in 1958. The original company later became a long-running local name, and current Encel materials describe it as a continuing family business built around that legacy. Some retailer and video sources also note that the brand was relaunched in the early 2020s after an earlier closure, but the core heritage consistently points back to the same 1958 foundation.
Today, Encel is best known for compact hi-fi systems and speaker-led components rather than a broad catalog of electronics. Current product coverage includes bookshelf speakers, a class-AB amplifier with phono input, and related system pieces sold as part of a modern, design-conscious stereo range. That makes Encel more of a curated hi-fi brand than a one-stop mass-market manufacturer, with emphasis on getting a complete listening setup rather than spanning every category from turntables to headphones.
In market terms, Encel sits in the niche boutique / upper-mid hi-fi space: approachable enough for serious domestic buyers, but positioned with enough heritage and brand identity to appeal to enthusiasts who value Australian lineage and an integrated system aesthetic. It does not read as a vintage-collector brand in the usual sense, nor as a sprawling high-end specialist competing at ultra-luxury levels. The strongest impression is of a revived local hi-fi name with a historically significant backstory and a contemporary, enthusiast-friendly product focus.
