Description
Overview
Miniature full-range speakers set in a rear cavity with a connector tail. Eleven models cover 4Ω and 8Ω coils at 1W, 2W or 3W, so a small enclosure can match the amplifier on hand.
Specifications
- Impedance: 4Ω or 8Ω by model
- Rated power: 1W, 2W or 3W
- 8Ω: 2030 1W, 2415 1W, 2112 1W, 1318 2W, 4020 2W, 4230 2W, 4330 2W
- 4Ω: 3516 2W, 2828 Gold 2W, 2828 Silver 3W, 4230 3W
- Termination: factory connector tail
Purpose
Voice prompts need a driver that drops into a moulded pocket with no cabinet, while amplifiers ship at a fixed load impedance. One cavity frame in several steps removes the guesswork.
Applications
- Smart home voice assistant boxes
- Doorbell and intercom prompts
- DIY Bluetooth speaker builds
- Kiosk and vending alerts
- Advertising display audio
How to Use
- Measure the cavity opening and depth, then pick the model that fits.
- Match impedance to the amplifier’s load; never fit 4Ω where 8Ω is specified.
- Seat the cavity against a smooth surface so the rear volume stays sealed.
- Caution: keep input at or below the model’s 1W, 2W or 3W rating; overdriving burns the coil.
- Sweep at low volume first to check for rattles.
