Electro-Voice Active Speakers FAQ: ETX-35P, Whelen PA Speaker & Small Orders

I'm a field coordinator for a regional AV integration and rental house. I've handled 240+ rush orders in nine years—some for a single speaker, a few for a temporary PA, and more than one for emergency-vehicle audio that had to ship before the end of the day. Last quarter alone, we processed 12 rush orders, and only one slipped. That one slipped because someone ordered a replacement based on a photo rather than checking the actual bracket on site.

This page isn't a spec sheet. It's a list of questions I get when someone is standing in front of a quote and needs to make a decision. My experience is mostly with mid-size rooms and small-to-medium installs, so if you're mixing a stadium tour, take this with a grain of salt.

Which electro voice active speakers should I put on a truck?

If you search for 'electro voice active speakers,' you'll get ZLX, EKX, and ETX. They're all solid, but they're not interchangeable. For utility work—weddings, classrooms, bar gigs—EKX is what I spec more than any other cabinet. It has enough power for vocals without sounding harsh. ZLX is the right call when the budget is tight and speech is the main use. ETX is the one I pull when a client says 'we need it loud but still clear.' My rule: buy the best DSP you can justify, not just the biggest woofer. The DSP is what saves you when a room is more live than expected. And check the amp module, not just the advertised wattage. That's where the reliability is.

Is the Electro-Voice ETX-35P 3-way powered loudspeaker worth the upgrade?

The Electro-Voice ETX-35P 3-way powered loudspeaker is not a light cabinet. I want to say it's around 80 pounds, but don't quote me—check the current spec sheet. It's the cabinet I choose when I need one box to cover both sides of a stage and still have headroom. The 3-way design is the part that matters. A separate mid driver keeps vocals from getting lost. In August 2024, a client called at 10 pm with a blown HF driver on the night before an outdoor festival. We loaded a refurbished ETX-35P and delivered it by 7 am. The extra trucking cost stung, but the show went on. Is it worth it? If your worst-case event involves a real drummer and a 150-person room, yes. If it's a pulpit with a podium mic, save the money.

What makes a Whelen PA speaker different from a regular loudspeaker?

A Whelen PA speaker is for vehicles: police cruisers, fire apparatus, ambulances. You're not sending music through it. It's a horn-loaded driver that projects siren tone and voice commands over ambient noise. The specs that matter are impedance, wattage, and the mounting angle. I've seen a rush order fail because someone matched the wattage but ignored the bracket. In May 2025, a client needed one for an ambulance going into service the next morning. A $40 bracket wouldn't have been the crisis; ordering the wrong one would have cost two days. The fix was asking for the VIN, a photo of the mounting holes, and the vehicle model before placing the order. Whelen's site has data sheets, and as of mid-2025 it still lists surface-mount and flush-mount options. But the site can't tell you which bracket the vehicle already has. So measure before you click.

Will a B2 mini subwoofer be enough for a small room?

The B2 mini subwoofer isn't going to shake a gymnasium. But 'mini' doesn't mean 'weak' in every context. For a small café, a studio, or a meeting room that just needs a little body, a compact sub is easier to place and tune than a big box. The common mistake is comparing it to a double-18 and calling it bad. That's like complaining a scooter won't tow a trailer. My move: put the B2 near a wall or corner, set the crossover around 80 Hz, and let the mains handle the midrange. Give it a clean power connection too. Compact subs are sensitive to hum, and most hum problems are cable routing, not the sub itself.

What if I'm looking for a 'Brodmann Vienna loudspeaker dealer North Carolina'?

If you typed 'Brodmann Vienna loudspeaker dealer North Carolina' into a search engine, here's the answer I'd give you. I'm not a dealer, so I won't name a storefront I haven't done business with. Start with high-end AV integrators in Charlotte, Raleigh, or Winston-Salem. Call them and ask whether they have access to Brodmann Vienna or its US distributor. If they do, ask if they'll sell a single loudspeaker. Don't apologize for that. A single-speaker order is legitimate. It's often how a small client builds a relationship with an integrator. And get the lead time in writing. High-end loudspeakers are sometimes made to order, so an accurate timeline is worth more than a vague 'two weeks.'

What's the question about powered speakers that nobody asks?

It's not wattage. It's firmware. Electro-Voice powered speakers have user presets and DSP updates loaded through a USB port. More than once, a rental cabinet sounded wrong and the culprit wasn't the driver—it was an old user preset from a previous gig. In March 2024, I watched a tech spend 45 minutes troubleshooting a stage monitor before checking the firmware version. A five-minute factory reset fixed it. If you're buying a used EV cabinet, reset it and update the DSP before you load it into a truck. The official EV product page lists current firmware notes. Do that in the shop, not at the venue.

Are active speakers always better than passive ones?

Everything I'd read early in my career told me active speakers are the obvious choice for anything portable. In practice, that's true for speed and convenience. You roll in, plug in, done. But for a fixed install where the amplifier sits in a rack 30 feet away, passive makes service easier. I can swap a blown amp module in the rack without lowering the speaker. I'm not saying active is bad. Passive is just the better fit when cables run through walls and you don't want to pull a heavy cabinet to fix an amp. Most of the Electro-Voice installs I do use passive for exactly that reason. There's room for both, and EV makes both for a reason. Also, if you're mixing passive and active cabinets in one system, don't align them by ear. Use a measurement mic and set an actual delay time. That's another area where integrated DSP helps, but only if you take the time to configure it.

Do you really take small orders?

Yes. Some of our best clients started with a single item: one microphone, one powered speaker, one Whelen PA speaker. We once shipped a single B2 mini subwoofer to a client in a remote town because their studio was missing bottom end. Normal lead time was five days; they needed it by Saturday. We paid extra for an air pickup and got it there. The shipping cost more than the margin on the sub, but that client now calls us first for system work. I'll never understand the small-order attitude some vendors have. Small doesn't mean unimportant—it means potential. When I was starting out, the suppliers who took my $200 orders seriously are the same ones I still call for $20,000 projects. So don't apologize for ordering one speaker. Ask for the same fast quote you'd get if you were buying twenty.
