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

  1. Measure the cavity opening and depth, then pick the model that fits.
  2. Match impedance to the amplifier’s load; never fit 4Ω where 8Ω is specified.
  3. Seat the cavity against a smooth surface so the rear volume stays sealed.
  4. Caution: keep input at or below the model’s 1W, 2W or 3W rating; overdriving burns the coil.
  5. Sweep at low volume first to check for rattles.
