Description

Overview

A square ultra-thin box speaker for notebooks and other shallow cavities, built in two footprints with a 6 mm overall thickness. It ships in 4 ohm 3 W and 8 ohm 2 W versions of both the 2030 and 3525 body.

Specifications

  • Impedance and power: 4 ohm 3 W, 8 ohm 2 W
  • Footprint codes: 2030, 3525
  • Variants: 2030 4 ohm 3W, 2030 8 ohm 2W, 3525 4 ohm 3W, 3525 8 ohm 2W
  • Overall thickness: 6 mm
  • Construction: square frame, small sealed cavity box

Purpose

A notebook lid has no room for a deep cone, yet the user still expects clean speech. The square cavity keeps radiating area high at 6 mm, and the 4 ohm 3 W option adds level where the amplifier can drive it.

Applications

  • Laptop and ultrabook speakers
  • 2-in-1 tablets with keyboard docks
  • Portable Bluetooth enclosures
  • Mini PCs and TV boxes

How to Use

  1. Pick 8 ohm for battery-first circuits, 4 ohm 3 W for more output.
  2. Confirm the amplifier is stable at that impedance.
  3. Mount on a foam gasket so the cavity seals to the housing.
  4. Match polarity to the other channel to avoid phase loss.
  5. Test quietly for rattle before closing the case.
  6. Caution: never exceed 3 W at 4 ohm; the 8 ohm part has a lower thermal limit.
