CTW-3914-108SE

Speakers Overview

The CTW-3914-108SE is a round tweeter speaker manufactured by Same Sky. It features an 8 Ohm impedance and a rated power of 10 W, with a maximum power handling of 15 W. The frequency response spans from 1.36 kHz to 20 kHz, with a self-resonant frequency of 1.7 kHz. Sensitivity is 87 dB at 1W/10cm. The unit utilizes a polyester cone and neodymium magnet, with top porting. Dimensions are 39.5mm diameter by 14mm height.

Speakers Feature Summary

• Utilizes a neodymium magnet for high efficiency in a compact form factor
• Features a polyester cone designed for clear high-frequency reproduction
• Includes top porting to optimize acoustic output direction

Speakers Applications

• High-frequency audio reproduction in consumer electronics
• Tweeter integration in multi-driver speaker systems
• Compact audio devices requiring precise sound projection

Speakers Procurement Notes

Verify the specific suffix 'SE' matches the required packaging or specification variant. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the operating environment stays within the specified temperature range. Check for any recent product change notices that might affect dimensions or materials.

Speakers Selection Notes

Select this component when a dedicated tweeter is needed for frequencies above 1.36 kHz. The 8 Ohm impedance must match the amplifier output requirements. Consider the 14mm height constraint for enclosure design. The top porting orientation dictates the mounting position relative to the listener.

Speakers Part Context

This model belongs to the miniature speaker category from Same Sky, formerly CUI Devices. It is part of a series designed for general-purpose audio applications where size and weight are critical factors. The company transitioned from CUI Devices to Same Sky, maintaining the same product lineage and specifications.

Speakers Replacement Considerations

Direct substitutes may include other 39mm round tweeters with similar 8 Ohm impedance and 10W rating. Verify compatibility with existing enclosure mounts and acoustic tuning. Check if alternative models offer improved sensitivity or different frequency cutoffs while maintaining the same physical footprint.
