Sound System for Speeches: What You Need for Toasts and Ceremonies

Nothing quiets a room like a toast nobody can hear. Guests in the back lean forward, the microphone squeals, and the best man's best line disappears. Speech sound is easier than music, but it has its own rules. This guide covers what you need, where it goes and how to avoid feedback.

Speech needs clarity, not volume

Music wants bass and volume. Speech wants clear midrange sound. The goal is for the farthest guest to hear each word without the nearest guest being blasted. That means more speakers at lower volume, spread evenly, instead of one big speaker at the front.

The most common problems:

• Feedback. A high squeal when the microphone hears the speaker and re-amplifies. Speakers should point away from microphones, and the mic should never stand in front of the speakers.
• Muddy sound. Low frequencies swallow words, especially in stone, brick or tile rooms. A mixer with a low cut helps.
• Echo. Big hard-surfaced spaces like lofts, ballrooms and churches bounce sound. Aim speakers at the guests, not the walls.
• Dead batteries. A mic that cuts out mid-toast is nearly always batteries or a weak connection.

What a basic speech setup includes

See microphone types for events to choose between handheld, lavalier and headset mics.

How many speakers?

For a room of 50 to 100 guests, two speakers placed on either side of the front are usually enough. Larger rooms need delay speakers, which are extra speakers placed partway back and delayed slightly, so sound reaches guests together. Outdoor ceremonies need more care because sound travels in the open. Add a speaker toward the back or use a bigger system so the back rows do not strain. A professional can calculate it for your space.

Rules of thumb only:

• Under 50 guests, indoors: one or two small speakers.
• 50 to 150 guests: two full-size speakers on stands.
• 150 plus, or a wide space: more speakers and a technician.

Ceremonies versus receptions

Ceremony audio has to carry vows to the back rows, and the couple should be miked, often with a lavalier on the groom or officiant and a handheld mic for the reader. Reception speeches usually use one handheld mic passed from speaker to speaker. Keep the DJ's music system and the speech system on the same speakers if you can, so the volume stays consistent, but agree who controls what.

Give the speakers a short script. Ask them to hold the mic 2 to 4 inches from the mouth, speak across it and not into the top, and test volume before the toast begins.

Power

A small system draws little power, but audio is sensitive to bad power. Avoid plugging it into the same circuit as heaters and caterer equipment. If you use a generator, put audio on its own outlet or small unit, and see quiet generator placement. The power checklist shows how to separate loads.

Chicago notes

Many Chicago venues have house systems or require approved AV vendors, and some have sound limits. Ask your venue whether outside audio is allowed, what outlets are available and whether the venue has a limiter. For outdoor events in parks, ask your park district about amplified sound rules; they vary.
