Start with the event's speech and music needs, room size, background noise, power access and whether you need a microphone. Compare published maximum SPL and coverage guidance for the exact model; advertised wattage alone cannot predict audience coverage. Check wireless-mic support and the exact permitted frequency band.
Toasts nobody can hear and a ceremony drowned out by wind are the most common event sound failures. Most are avoided by choosing the right speaker and placing it well.
Match coverage to the program
| Use | Planning question |
|---|---|
| Ceremony and speeches | Can the speaker carry clear speech across every seat? |
| Background music | Is the desired level comfortable without overpowering conversation? |
| Dancing | Does the setup include enough low-frequency output for the room and program? |
What to compare
| Spec | Why |
|---|---|
| Woofer size | Larger woofers move more air and reach lower |
| Max SPL (dB) | A better loudness comparison than peak watts |
| Power | Battery runtime, or mains only |
| Inputs | Mic, instrument, line, Bluetooth |
| Built-in mixer | Lets you control mic and music separately |
| Wireless mic | Included, or a receiver you add |
| Weight and handles | You will carry it |
| Stand mount | A 35 mm pole socket for tripods |
Wireless microphones and the law
In the US, wireless microphones may not use 617–652 or 663–698 MHz after the FCC’s July 2020 transition deadline. Limited segments of the 600 MHz guard band and duplex gap remain available under separate rules, so check the microphone’s exact frequency and authorization against the FCC’s wireless-microphone guidance. Many new event mics use 2.4 GHz or other permitted UHF ranges.
Placement
Put speakers on stands above head height, slightly in front of the speaker or officiant, and angled toward the guests. Keep the mic behind the speakers to avoid feedback.
Outdoor events also need power; see our party tent guide and string lights guide. For a small event where a consumer speaker may be enough, compare a portable PA with a Bluetooth speaker. Browse light, sound and photo.
Common questions
How many speakers do I need for an event?
It depends on room shape, audience size, background noise and program. Use the manufacturer's coverage guidance, then check speech intelligibility throughout the space during a sound test.
Are speaker watt ratings reliable?
Peak watt claims vary between brands. Compare maximum SPL in decibels and speaker size instead.
Can I use a Bluetooth speaker for a wedding?
For music in a small room, maybe, but speeches need a microphone input and enough volume to cover talking guests.
How do I stop microphone feedback?
Place speakers in front of the person speaking, facing the audience, and keep the mic out of the speaker's direct path.
