CMS-3648-158SP

Speakers Overview

The CMS-3648-158SP is a round general-purpose speaker manufactured by Same Sky. It features an 8-ohm impedance and a 1.5-watt power rating. The unit has a body diameter of 36 mm and utilizes a top port design. The frequency response ranges from 480 Hz to 14 kHz, with a self-resonant frequency of approximately 500 Hz. It employs a neodymium iron boron magnet and a paper cone. The component is designed for panel mounting and offers a sound pressure level of 90 dB.

Speakers Feature Summary

• Top port acoustic design for directed sound output
• Neodymium iron boron magnetic structure for high efficiency
• Paper cone material for balanced audio reproduction
• Panel mount installation style for secure integration

Speakers Applications

• General purpose audio signal indication
• Industrial control panel status alerts
• Consumer electronics audio feedback systems
• Medical device auditory signaling

Speakers Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to ensure correct terminal type and acoustic port orientation. Confirm impedance and power ratings match the target circuit requirements. Check RoHS compliance status if restricted substances are mandated. Ensure mechanical dimensions fit the designated enclosure space. Validate operating temperature range suitability for the intended environment.

Speakers Selection Notes

Select this model when a compact round speaker with top porting is required. The 8-ohm impedance suits standard amplifier outputs. The 1.5-watt rating provides adequate volume for short-range signaling. Consider the 36 mm diameter for panel cutout compatibility. Evaluate the 90 dB SPL for sufficient audibility in moderate noise environments.

Speakers Part Context

This component belongs to the CMS series of speakers from Same Sky. The series includes various sizes and configurations for different audio applications. The CMS-3648-158SP represents a mid-size option within the lineup. It shares common design principles with other models in the family but differs in physical dimensions and acoustic performance characteristics.

Speakers Replacement Considerations

CMS-3648-158SP-67 is a documented variant with similar specifications. Verify terminal type and port orientation differences before substitution. Ensure mechanical fit and electrical parameters remain compatible with the existing design.
