How We Built a Small Venue Sound System With JBL Column Speakers (Without Breaking the Budget)

The email came in on a Tuesday afternoon. Our CEO wanted the event space, the lobby, and the small patio to 'sound professional' before the annual client mixer in six weeks. That's a vague sentence that, for a procurement person, translates to: 'You have a limited budget, and I expect zero complaints.'

I'm a cost controller at a 35-person marketing agency. I've managed our AV spending (roughly $40,000 a year) for four years, negotiated with more vendors than I can count, and built a cost tracking spreadsheet that probably needs its own IT ticket. I'm not an audio engineer. I just know how to compare total cost of ownership.

My 'This Is Fine' Failure in 2023

The reason I cared so much this time is that I tried the cheap route once before.

Back in 2023, we had a smaller event in the same space. I convinced myself that one large JBL bluetooth speaker placed on a table would cover 60 people. Everyone with actual audio experience told me it wouldn't. I didn't listen. The back half of the room couldn't hear the host, and the mic feedback made people literally flinch. I only believed that room coverage matters after ignoring it and watching the results.

So for the 2025 mixer, I went into full TCO mode.

Getting Real Quotes (and Getting Ignored)

I asked three suppliers for quotes.

The first one, a national AV company, sent back a one-page quote that said 'superior sound quality' three times. According to FTC business guidance (ftc.gov), advertising claims should be truthful and substantiated. I asked for a spec sheet. They never replied. That told me more than any brochure.

The second supplier told us our order was 'below our minimum project threshold.' The project was going to be around $4,500. I get that big integrators need big projects, but it still stung.

The third was a local music shop that we'd used once for a secondhand cable order. The owner spent 45 minutes on the phone asking questions about the room, not upselling me. When I said, 'I know this isn't a giant order,' he said, 'Small orders are how we prove ourselves.' That's exactly the kind of supplier I want to work with.

In my opinion, that's the difference between a vendor and a partner. Small doesn't mean unimportant. It means potential.

The System We Actually Bought

Here's what we ended up with, based on the local shop's recommendation and my spreadsheet.

The Main Event Room: JBL Column Speakers

The main room got the JBL column speakers. Specifically, two JBL EON ONE Compact units. They're the upright portable systems with a built-in mixer and Bluetooth. I almost skipped them because they look small, but the spec sheet says 124 dB max SPL, and they're meant for exactly this kind of 100-150 person room.

We put one on each side of the stage. We didn't need a separate mixer for the live sound because the EON ONE has eight inputs built in. That's not the same as a real mixing console, but for a client mixer, it's enough.

I'll admit, I was skeptical of powered column speakers. My instinct as a cost controller is to buy separate components so you can replace them individually. But the all-in-one design saved us on cabling, cases, and setup labor. The TCO spreadsheet liked it, even if my inner 'modular is better' voice didn't.

The Recording Corner: Focusrite Audio Mixer and On Stage Stands

The same room has a small recording/podcast corner. For that, we chose a Focusrite audio mixer. To be precise, it's the Scarlett 18i8, which is technically an audio interface, not a traditional mixer. But we run it as our front end for microphones and monitoring, so in my notes I called it the Focusrite audio mixer. That's the thing I love about this setup: it does more than one job.

We mounted a pair of JBL 305P MkII studio monitors on On Stage SMS6000-P studio monitor stands. I'd never bought On Stage before, but the stands are stable, cheap, and easy to adjust. The SMS6000-P model is a two-pack, which made the price even better. Total for the stands was around $99, though I might be misremembering the exact figure.

The Lobby and Patio: One Large JBL Bluetooth Speaker (Plus the Amp I Messed Up)

For the patio, we ordered one large JBL bluetooth speaker. We went with the JBL PartyBox 310 because it's battery-powered and loud enough to be heard outside without being overkill. It wasn't for the main room. The shop owner said that clearly, and this time I listened.

The lobby ceiling speakers were a different story.

We needed a small power amplifier to drive them. I kept typing '100 power amplifier' into the search bar because the listing kept showing '100W power amplifier.' I had the specs open, the 70/100V transformer taps, the ohms, all of it. And then I got impatient.

The Mistake That Cost $60

Here's where I ate humble pie.

I knew I should verify that the amplifier I picked actually matched the 70/100V line transformer on the lobby speakers. But we were in a rush to get the order in before the weekend, and I thought, 'what are the odds I misread the product page?'

Well, the odds caught up with me.

The amp arrived, and it was just a regular 100W stereo amplifier with no high-impedance output. Completely wrong for our setup. We had to send it back, pay a 15% restocking fee, and wait another four days. That was a $60 mistake that could have been avoided by thirty seconds of re-reading the manual. (Which, honestly, is the most procurement sentence I've ever written.)

The shop owner didn't laugh at me when I explained it. He just said, 'Happens all the time. You want the 100V version?' That's why we went with him instead of the internet.

What the Event Actually Sounded Like

Six weeks later, the client mixer happened. I stood in the back of the room for the first speech, and I could hear every word without straining.

The JBL column speakers covered the space. The Focusrite audio mixer handled the podcast station. The On Stage SMS6000-P studio monitor stands kept the monitors off the desk, which looked better and sounded better. The large JBL bluetooth speaker lived on the patio and did exactly what it was supposed to do.

The total invoice came to around $4,700. I want to say it was $4,632, but don't quote me on that. I'd budgeted $5,000, so we actually came in under. That almost never happens.

What I'd Do Differently

If you're in the same position, here's my honest advice.

First, don't use a large bluetooth speaker as a PA system for a room full of people. It's a great backup, not a main system. I learned that the expensive way.

Second, pay attention to the difference between a 100-watt amplifier and a 100V line amplifier. They are not the same thing. One of them will drive the ceiling speakers in an office. The other will sit in a box and mock you.

Third, and this is the one I care most about: treat small orders like real projects. We gave the local shop less than $5,000, and they gave us three phone calls of support, honest recommendations, and no unnecessary upselling. The numbers said the online retailer was cheaper. My gut said the local shop would actually help us if something went wrong. I went with my gut, and it was the right call.

That's not a sentimental point. It's a TCO point. Good suppliers save you money over the long term by preventing the '$60 restocking fee' kind of mistake. If you ask me, that's worth more than the 18% discount on paper.
