You know a demo car is doing its job when people stop mid-conversation and just stare. Unveiled at KnowledgeFest in Las Vegas last week — a major mobile electronics training and networking event for installers, retailers and manufacturers — this extraordinary Mercedes-Benz SL300 Gullwing restomod by S-Klub LA blended classic automotive sculpture with cutting-edge performance and reference-grade audio.
Oh, and it runs on a full Tesla drivetrain. So it doesn’t just look fast — it is.
But let’s talk about the sound system, because this build is essentially a rolling showcase for Audison’s flagship Thesis range, a lineup widely regarded as some of the most advanced high-end car audio equipment on the market.
Front and rear Thesis speakers are driven by dedicated Thesis amplification, while a Hertz Mille Line subwoofer up front handles the low frequencies with authority rather than brute force. At the centre of it all sits the formidable Audison Thesis Venti amplifier, supported by additional TH-series amps to ensure every channel gets the power — and control — it deserves.
The result? Exceptional clarity, huge dynamic range and the kind of balance that makes seasoned audiophiles quietly nod in approval.
It’s also a reminder that demo vehicles still matter. In an era of spec sheets and online launches, nothing sells premium audio quite like hearing it properly installed in a no-expense-spared build.
For UK dealers and installers keen to explore the Thesis ecosystem, Audison is distributed by Four Car Audio.
