CDS-4837-54L100

Overview

The CDS-4837-54L100 is a general-purpose speaker manufactured by Same Sky. It features a square frame measuring 48mm x 48mm with a depth of 37.6mm. The unit has an impedance of 4 Ohms and a power rating of 5 W. Its frequency response ranges from 170 Hz to 20 kHz, with a self-resonant frequency of 136 Hz. The speaker utilizes a polyurethane and paper cone, a neodymium magnet, and terminates via 100mm wire leads.

Feature Summary

• Square frame design for compact mounting applications
• Neodymium magnetic structure for efficient performance
• Polyurethane and paper composite diaphragm material

Applications

• General purpose audio output devices
• Consumer electronics enclosures requiring square form factors
• Industrial control panels with limited depth

Procurement Notes

Verify the specific termination style matches the target PCB or harness design, as this model uses fixed 100mm wire leads rather than solder terminals. Confirm that the 48mm square footprint and 37.6mm depth fit within the mechanical constraints of the intended enclosure. Ensure the 4 Ohm impedance aligns with the amplifier output specifications to prevent mismatch issues.

Selection Notes

Select this component when a square profile is required instead of standard circular speakers. The 5 W power handling suits moderate volume applications. Consider the 170 Hz low-frequency limit if deep bass reproduction is necessary, as this model is optimized for mid-range and high frequencies. The wire lead termination simplifies integration but requires sufficient cable routing space.

Part Context

This speaker belongs to Same Sky's standard general-purpose lineup, formerly associated with CUI Devices. It represents a common industrial audio solution designed for cost-effective mass production. The square geometry distinguishes it from the more prevalent round speaker variants in the same series, offering alternative layout options for designers.

Replacement Considerations

Direct substitutes must match the 48x48mm square dimensions, 4 Ohm impedance, and 5 W rating. Circular speakers like the CLS series are not direct replacements due to different mounting hole patterns and acoustic characteristics. Verify equivalent sensitivity and frequency response curves before swapping.
