The Best AV Companies in St. Louis

Great events live or die by what people see and hear. A keynote nobody can hear, a slideshow that flickers out, or a gala lit like a parking garage can undo months of planning. St. Louis is lucky to have a deep bench of audio visual talent, and after years of working alongside local vendors, venues, and planners, we've put together our list of the five best AV companies in the Gateway City.

Here's our countdown.

5. Planorus

Based in the St. Louis area, Planorus is a great fit for corporate meetings, galas, and nonprofit gatherings that need dependable gear without a lot of fuss. They offer ready-made packages built around projectors, screens, and small PA systems, and can add lighting, staging, and on-site technicians as needed. Free delivery and setup within the greater St. Louis area makes them an easy call for smaller events with tight budgets.

Best for: Meetings, presentations, and budget-friendly event packages

4. Heard Global

Heard Global has been producing events for over two decades, and many St. Louis planners remember them by their former local name, Events/com. They've grown into a full event services company covering AV production, event design and décor, brand activations, and hybrid events, with a local warehouse in St. Louis supporting their work here.

Best for: Turnkey events that combine AV with décor and experiential design

3. Markey's

Founded in 1959, Markey's is one of the most established names in event technology, and it's 100% employee-owned. That ownership structure shows up in the work: their crews treat each event like it's their own. They're a trusted partner for hotels, convention spaces, and large corporate meetings.

Best for: Hotel and convention events that need a long-standing, proven partner

2. St. Louis Audio Visual

With roughly three decades of experience, St. Louis Audio Visual specializes in large-venue sound, lighting, and video for corporate meetings, conferences, exhibitions, concerts, and staging. Now operating as a division of Conference Technologies (CTI) out of Maryland Heights, they pair their event production roots with the resources of a national AV integrator.

Best for: Large conferences and exhibitions that need serious technical muscle

1. TSV Sound & Vision

Our top pick is TSV Sound & Vision, a full-service AV and event production company headquartered on Hampton Avenue in St. Louis, with a second location in Austin and a client list that stretches nationwide. TSV has spent more than ten years delivering lighting, sound, backline, video, LED, and staging for everything from corporate conferences and fundraising galas to indoor and outdoor concerts.

What sets TSV apart is how they approach the work. Strategy calls, on-site visits, and professional technicians are standard, not upgrades. Their team handles everything from pre-production drawings and schedules to webcasting, live streaming, set design, and round-the-clock delivery and operation. They're regulars at venues like the Ritz-Carlton and the Four Seasons, and they've built immersive brand activations for names like HBO and Ricoh at SXSW.

If you want an AV partner who takes the stress off your plate and makes your event look and sound incredible, TSV is the first call to make.

Best for: Anyone who wants creative, full-service production done right, from galas to concerts to national brand activations

Choosing the Right AV Partner

Every company on this list brings something valuable, but the right choice depends on your event. Before you book, ask about on-site technical staff, what's included in delivery and setup, and whether they've worked in your venue before. The best AV partners ask as many questions as you do.
