Ascendo The24 SUB PRO passive infrasonic subwoofer Subwoofer (Passive) This year we're looking at completely changing our demo room setup and unfortunately that means moving on our beloved infrasonic subwoofer. Due to sheer size and weight shipping is not possible unless organised by the buyer. Demonstration is definitely possible if you're in Melbourne but is for serious buyers only. Measurement data is available on the Ascendo website.https://www.aia-cinema.com/products/the24-sub-pro-passive-sealedIf you've been thinking about the next big step in your cinema room this isAscendo The24 SUB PR
The timing matters a bit because this is an established passive infrasonic design rather than a fast-moving new-gen release, so the key question is whether you want serious output and can live with the footprint and system demands. Against your market anchor, A$14,899 is clearly ambitious versus the A$5,276 median and even the A$10,008 75th percentile, so it sits above the typical used band rather than in bargain territory.
What makes it worthwhile is the scale: this is the kind of sub that appeals to buyers chasing deep extension, high headroom, and the “go big once” approach for a reference theater. If it’s complete, clean, and from a careful owner, the upside is in buying a niche, heavyweight piece that doesn’t come up often and can anchor a top-tier system for years. At this price, I’d want strong proof of originality, matching accessories, and any service history, because the premium only makes sense if condition is genuinely excellent.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
