How to Design a Speaker System for Corporate Events in San Francisco
How to Design a Speaker System for Corporate Events in San Francisco Choosing the right speaker system for a corporate event isn’t just a gear decision — it’s an engineering problem. Get it wrong and your audience is either straining to hear a panelist from the back row, or wincing from reverb bouncing off the walls of a cavernous hotel ballroom. In this guide, WestWave AV’s William Cook sits down with Richard Healy, a veteran A1 engineer based in the San Francisco Bay Area, to break down how professionals approach audio system design for corporate events of every scale. Start With the Room, Not the Gear The single most important factor in designing an audio system for any corporate event isn’t the speaker brand or the budget — it’s the physical space. Room size, shape, ceiling height, and acoustic characteristics all drive the decision before a single piece of gear is selected. As Richard explains it: “Is it a ballroom? Is it a breakout room? You don’t want to over-spec. It’s a cost issue, it’s a power issue, and it might be a physical limitation — what the room can actually have.” Every subsequent choice flows from this foundation. For corporate AV in San Francisco specifically, you’ll encounter a wide range of venue types — the intimate boardrooms of FiDi hotels, the mid-size ballrooms at Moscone-adjacent properties, and the vast general session spaces used for large tech conferences. Each demands a different approach. Pro Principle Always size for the minimum that gets the job done, then scale up if the budget, power, and space allow. You can always turn a speaker down — you can’t make a physically inadequate system perform beyond its limits. The Minimum Starting Point: Why 8-Inch Speakers Are the Floor for Corporate AV When it comes to speaker size, Richard draws a clear line. For any corporate event, 8-inch speakers are the floor — the smallest cabinet that makes practical sense for real reinforcement work. “Anything smaller than an eight or ten isn’t going to be any help,” he says. In a room of 35–40 chairs — a typical breakout or boardroom session — a pair of 10-inch or 12-inch cabinets will do the job comfortably. The key insight: because you can always turn down the volume, it’s smarter to have slightly more speaker than you need than to run an undersized system at its limit. Running cabinets near their maximum output introduces distortion, reduces headroom for unexpected moments (applause, feedback spikes), and forces louder volume levels on the people seated closest to the speakers — destroying the uniformity that should be the primary goal of any reinforcement system. Point Source vs. Line Array: Choosing the Right Tool This is the question WestWave AV gets asked most often when scoping a corporate production. The short answer: point source for smaller, more contained spaces; line arrays when the room gets large, wide, or deep enough that a handful of cabinets can’t uniformly cover the audience. What Line Arrays Actually Do Differently Line arrays aren’t just bigger point source speakers. They behave differently at a physics level. A properly configured line array controls the vertical dispersion of sound, allowing audio to travel further into a room while maintaining consistent SPL (sound pressure level) from the front of the audience to the back. “People in the front of the audience are getting a similar volume as people in the middle or back,” Richard explains. That consistency — every seat hearing roughly the same thing — is the defining goal for corporate audio. Unlike a concert where some energy and excitement can come from loud, immersive sound, a corporate general session needs the audio rentals to be invisible. Presenters should be clearly heard, not amplified in a way that calls attention to itself. When Point Source Wins For spaces under roughly 500 people, point source cabinets are often the right call. They’re faster to deploy, simpler to dial in, and in the right room, can deliver excellent uniformity with strategic placement. Richard highlights the Siva (a relatively newer compact line array hybrid) as a strong middle-ground option for wide rooms: “They’ve got a really wide throw,” making them effective in spaces where you have width to cover but not the ceiling height or rigging infrastructure for a full line array. Workhorses like the QSC K.2 Series remain a go-to point source cabinet for corporate AV across the Bay Area. “The ultimate goal on these corporate shows is clean, high-quality audio that isn’t distracting for the audience — uniform across the room, regardless of where they’re sitting.”— Richard Healy, A1 Engineer, San Francisco Bay Area Factor Point Source Line Array Ideal audience size Up to ~500 500+ (or complex rooms) Setup speed Faster More complex Sound uniformity over distance Moderate Excellent Requires rigging/flying Rarely Often preferred Works well in reverberant rooms Yes (at lower SPL) Depends on config Aesthetics / visual footprint Visible on stands Flyable, less obtrusive Cost relative to scale Lower Higher Room Acoustics: Why Over-Speccing Your PA Can Actually Hurt Sound Quality One of the most counterintuitive lessons in corporate AV is that more speaker power can make a room sound worse — not better. In highly reverberant spaces (think marble-floored hotel lobbies, ballrooms with hard ceilings, or spaces with a lot of glass), driving a large PA at high SPL creates a wash of echo that makes speech intelligibility almost impossible. In these situations, Richard recommends a distributed approach: “Smaller point source cabinets placed strategically around the room as delays at a lower volume. You get coverage without screaming loud.” The result is cleaner, more intelligible audio across the room — which is always the priority for corporate speech reinforcement. The inverse problem is just as real. Two 12-inch cabinets on either side of a stage in a wide, reverberant room will have to be driven loud enough to reach the back — which means the people in the front rows are sitting too close to
