Peerless by Tymphany TC9FD00-04 Full-range Woofer

The Peerless by Tymphany TC9FD00-04 is a full-range broadband woofer designed to deliver clear, natural sound in compact speaker systems. This versatile driver excels in applications such as small bookshelf speakers, desktop audio monitors, and portable Bluetooth enclosures, where its wide frequency response eliminates the need for a separate tweeter. It is also an excellent choice for DIY audio projects and replacement drivers in vintage radios or multimedia speakers.

At the heart of this woofer lies a paper cone, chosen for its lightweight yet rigid properties, which ensures accurate and natural audio reproduction with minimal coloration. The total Q factor (Qts) of 1.0 indicates a well-damped response suitable for sealed or small vented enclosures, while the high sensitivity of 89.7 dB SPL at 2.83V ensures efficient power handling. With a nominal diameter of 88.9 mm, a mounting depth of 51 mm, and a cut-out diameter of 73 mm, this driver fits neatly into space-constrained designs. The 4-hole screw pattern on an 89.5 mm diameter circle simplifies installation, and the 7.7 mm linear excursion (Xmax) allows for impressive bass extension. Low DC resistance (Re) of 3.1 ohms and minimal voice coil inductance (Le) of 0.057 mH contribute to excellent transient response and control.

This full-range woofer combines versatility with technical precision, making it an ideal foundation for high-quality, space-efficient audio systems.
