DS18 SQT1
The PRO-SQT1 (commonly referred to simply as SQT1) is a 1.3-inch multi-mount PEI mini dome tweeter pair designed to deliver clear, crisp high-frequency sound for car audio systems and custom installations. Built with a lightweight 0.8″ voice coil, neodymium magnet, and durable PEI (polyetherimide) dome with ABS housing, it handles 15 W AES (30 W RMS) and up to 60 W peak power while maintaining a 4-ohm impedance and ~92 dB sensitivity. The tweeter produces refined treble across a frequency range of approximately 1 kHz to 20 kHz, enhancing vocals and high-end detail with minimal distortion. Its versatile mounting options — flush, angled, or surface — make installation easy in a variety of locations, from dashboards to custom pods, making the SQT1 a great upgrade for factory audio systems or compact high-frequency setups.
