Why audio gets skipped in the buying decision
Buyers obsess over panel brightness, touch points and processor specs, then forget the speakers until the first video call or lesson in a real room. That's the moment the built-in audio either carries the room or doesn't. An interactive flat panel isn't a home TV sitting two metres from a sofa — it has to project clear sound across a classroom or a meeting room, and the built-in speakers are the first line of that job.
The question most buyers should be asking isn't "does it have speakers" — nearly all of them do. It's "are the built-in speakers enough for the room I'm putting it in." The answer depends on room size, room acoustics and what the panel is used for.
What the built-in speakers actually deliver
A quality interactive flat panel ships with two front-facing speakers, typically 2 × 15W. That's enough to fill a standard classroom or a mid-size meeting room for a presenter's voice, a video lesson or a video call. Two front-facing drivers matter because the sound points at the audience rather than down at the floor, which is what you get with cheap panels that tuck small speakers in the back.
What 2 × 15W won't do is turn a lecture hall into a concert. In a large space — a big auditorium, a training room holding 60 people, a hall with hard surfaces that echo — the built-in speakers start to strain, and you'll want an external sound system or ceiling speakers wired in.
When the built-in audio is enough — and when it isn't
Standard classroom: built-in 2 × 15W is enough for daily lessons, video and screen sharing. No external audio needed.
Meeting room (8–12 people): built-in audio handles video conferencing and presentations cleanly. The microphone array matters more here than the speakers, because the far end of the call needs to hear the room.
Large auditorium, lecture hall, or open-plan training space: add external speakers or a ceiling system. Built-in drivers weren't designed to cover a 200-seat room.
The microphone side matters just as much
Audio cuts both ways. In a hybrid meeting, the people on the call hear the room through the panel's microphone array, not the speakers. That's why a panel built for video conferencing pairs its speakers with a proper microphone array — Lonton uses an 8-microphone array, which picks up voices across the room instead of just whoever is standing closest. If you're outfitting a room for hybrid work, check the microphone array as carefully as the speakers. Our guide to built-in camera and microphone vs buying separately walks through the trade-off.
How Lonton handles audio
Lonton has been manufacturing interactive flat panels since 2005 from a 100,000-square-meter facility with 15 production lines. Every panel ships with two front-facing 15W speakers and an 8-microphone array, paired with a 48MP camera — the audio and video are built to work together out of the box, so a hybrid meeting or a classroom lesson sounds as clear as it looks. If a space genuinely needs more sound than the built-in drivers provide, the panel's ports let you wire in external speakers without fuss.
If you're not sure what size panel fits your room before you think about audio, our guide to choosing the right interactive flat panel size is a good next read.

Frequently asked questions
Do interactive flat panels have built-in speakers?
Yes. Quality panels ship with two front-facing speakers, typically 2 × 15W, which handle a standard classroom or meeting room.
Do I need external speakers for a large room?
For a large auditorium, lecture hall or open-plan training space, yes — add external or ceiling speakers. Built-in drivers aren't sized for 200-seat rooms.
What matters more for video calls, speakers or microphones?
The microphone array matters more, because remote participants hear the room through it. Look for an 8-microphone array on a hybrid meeting panel.
Can I connect external speakers to an interactive flat panel?
Yes. Most panels, including Lonton's, have audio-out ports for wiring in an external sound system when a room needs more output.
