'A total gamechanger for big bass in a small space': I heard a groundbreaking new subwoofer driver that fits in a tiny box 6x smaller than a regular sub, but can punch you in the gut like it's a home theater beast with its 'powerful but tight' sound

The GSS Model 1 transducer held in a man's hand, showing its small size.

I recently visited the High End Show in Vienna, where the world's top audio companies show off their latest and greatest creations. The show mostly focuses on ready-to-sell products — of the kind that we chose in our Best in Show at High End Vienna 2026 Awards — but it's also where interesting new audio components makers show off what they're making to other companies, to use in their creations.

One of these companies at the 2026 show was GSS, showing off a new bass driver called the Model S1. It's a very slim transducer, just 62.5mm tall and 299mm wide, and is capable of operating in a box with a volume of just 1.75 liters.
