Description
Overview
Rectangular plastic-frame loudspeaker with an internal magnet, available in several sizes and two impedance/power ratings. The metal rear plate carries the impedance and power marking, and the frame has four corner holes for screw mounting.
Specifications
- Impedance and power: 8Ω 2W, or 4Ω 3W (marked on the magnet plate)
- Available sizes: 16 × 35mm / 20 × 40mm / 28 × 40mm
- Frame: rectangular black plastic with four mounting holes
- Diaphragm: treated paper / composite cone with surround
- Magnet: internal ferrite magnet, metal rear plate
- Terminals: solder lug terminals marked + and −
Purpose
A rectangular speaker fits into the narrow spaces typical of flat electronics, where a round speaker of the same cone area will not go. The lower-impedance 4Ω version draws more power from the same amplifier and plays louder; the 8Ω version is the safer match for amplifiers rated at 8Ω.
Applications
- Televisions and computer monitors
- Digital photo frames and small display devices
- Audio equipment, radios and intercoms
- General electronics and DIY audio projects
How to Use
- Measure the available mounting space and choose the size that fits — check both the frame footprint and the depth behind the baffle.
- Match the impedance to your amplifier’s rating. Connecting a 4Ω speaker to an amplifier rated only for 8Ω can cause overheating.
- Fix the speaker with screws through the four corner holes, with the cone facing out through the grille.
- Solder the leads to the terminals, observing the + and − markings so the speaker is in phase with any other speaker in the system.
- Seal any gap between the frame and the panel — an air leak around the frame noticeably reduces bass output.
