SVS’s PB13 Ultra has a strong reputation: it’s a big, deep-reaching ported sub that still has real authority for home cinema and is unusually clean for its size. At A$1,650, this looks like a strong deal versus the typical used market anchor here: it sits well below the A$1,751 25th percentile and comfortably under the A$1,801 median.
That makes it especially attractive if it’s in genuinely good shape, because the PB13 Ultra is still a serious low-end performer with excellent output and extension. The main upside is getting flagship-level bass for mid-tier money; if the finish is tidy and it’s been well cared for, this is the kind of listing worth moving on quickly.

SVS Sound emerged in 1998 from a garage in Youngstown, Ohio, founded by a team of passionate audio engineers frustrated with overpriced, underwhelming subwoofers. Headquartered in the U.S., the brand disrupted the market by selling high-quality subs directly to consumers online, bypassing traditional retail markups while leveraging American manufacturing and cutting-edge engineering. This direct-to-consumer model, combined with rigorous testing, quickly established SVS as a force in affordable performance audio.
The company specializes in subwoofers, which remain its cornerstone with five dedicated lines from the entry-level 1000 series to the flagship Ultra series, but has expanded into full-range speakers, wireless audio devices, and cables. Under President and CEO Gary Yacoubian, SVS delivers sophisticated technology and immersive sound across home theater and hi-fi categories, prioritizing precision drivers, advanced amplification, and real-world optimization without venturing into amplifiers, turntables, DACs, or headphones.
SVS holds a commanding position as the world's top subwoofer brand and a leading "bang-for-the-buck" speaker maker, blending reference-level performance with mid-tier pricing to appeal to discerning buyers seeking high-end results on a budget. No longer just a niche disruptor, it boasts global reach through online and retail channels, earning acclaim for democratizing exceptional audio.
