The Eighth Rule is a speakeasy and social dining experience hidden inside The Westin St. Francis hotel in San Francisco, California. Created by Golden State Warriors star Stephen Curry in partnership with The MINA Group, this intimate venue was conceived for elevated cocktails, conversation, and lingering.
A Meyer Sound system completes the experience, aligning with the venue’s meticulous attention to detail and carefully crafted atmosphere.
With a contemporary speakeasy concept, tucked behind an unmarked door near Union Square, the intimate 40-seat space takes its name from bourbon’s seven official production rules. Guests are invited to “create their own Eighth Rule” through the ritual of sharing a drink and gathering together. Warm wood finishes, a curved ceiling, and leather seating establish an elegant and welcoming atmosphere. For the owners and design team, the sound system needed to reflect the same level of care: present enough to shape the character of the room, yet discreet enough not to intrude, allowing the experience itself to take centre stage.

Providence SAV (Sound and Vision) served as the project integrator. The Eighth Rule required a low-profile sound system that supported its intimate character as a bourbon lounge, while offering enough headroom to accommodate higher-energy special events when needed. For Jeff Ehrenberg, founder and CEO of Providence SAV —whose background includes high-end recording studios and hospitality projects— this approach aligns with his broader mission to introduce premium audio solutions into restaurants and bars, elevating the sonic experience to the same level as design and cuisine.
In many restaurants, the interiors are spectacular and the food is outstanding, but sound often takes a back seat. Tens of thousands are invested in design, and in the end the audio system is left to a low-voltage contractor who hangs a few speakers. I’ve been a fan of Meyer Sound for decades. When I started working in live sound in the Bay Area in the nineties, moving from typical P.A. systems to Meyer Sound was eye-opening. It showed me what the true next level of sound quality could be, says Ehrenberg.

For The Eighth Rule, Providence SAV collaborated with Meyer Sound’s Daniel Rivera and Tom Dalske, who modelled the space using the MAPP 3D™ system design and prediction tool. The goal was to achieve even coverage and musical clarity throughout the room, with special attention paid to the transition between the different seating levels.
The system comprises 14 UP-4slim™ ultracompact installation loudspeakers and three USW-112P™ compact subwoofers, powered by two MPS-488X™ power supplies and processed by the Galileo® GALAXY 408 Network Platform. “For The Eighth Rule, the UP-4slim and the 112 made perfect sense”, explains Ehrenberg. “The space has fewer than fifty seats, so having something compact that could deliver the sound we needed without drawing attention was ideal”.
The bar’s architecture presented both a challenge and an opportunity for system design. Guests enter a lower seating area, with three steps leading up to an upper level; both zones needed to feel sonically unified while still allowing for control. As a speakeasy, the space depends on clear, close-range conversation, making coherence between zones an acoustic priority.

Tom calibrated the system so that the sonic transition between the two levels feels completely seamless, maintaining a cohesive experience as guests move through the space. Most nights are about setting the right atmosphere for cocktails and conversation, but when the volume is turned up, the system can deliver a club-level experience without becoming harsh or uncomfortable, Ehrenberg notes.
The interior finishes also contribute to acoustic control, naturally diffusing reflections and reducing low-frequency buildup.
From the venue’s perspective, the sound system is considered an integral part of the concept, not an add-on. “The Eighth Rule was designed as an intimate space for people to enjoy exceptional bourbon, cuisine, and conversation. Details matter here, and the sound system is part of that experience”, says Cori Tahara, VP of Development at The MINA Group. “The Meyer Sound installation helps the room feel relaxed and inviting, even as the energy builds throughout the night”.
For Ehrenberg, projects like The Eighth Rule reflect a broader shift in how the hospitality sector approaches audio.
In hospitality, many senses are stimulated —taste, smell, presentation, interior design— but hearing is often overlooked. When the sound is right, it elevates everything else. Guests relax and become more open to the full experience, he concludes.
