Speaker 1635mm 2040mm 2840mm Speaker 8R2W 4R3W Rectangular Plastic Inner Magneto Elastic Wave Navigation Digital Speaker

설명

개요

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.

명세서

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 −

목적

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.

사용방법

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.
