Engineered for high-fidelity audio builds, this 8-ohm driver combines precision with versatility, making it a standout choice for discerning enthusiasts.

Ideal for use in sealed or ported enclosures, the CHR-90 Champ excels in stereo systems, desktop monitors, and custom speaker projects where space is at a premium but sound quality cannot be compromised. Its full-range capability eliminates the need for a separate tweeter in many designs, simplifying construction while maintaining a cohesive, natural soundstage. Whether for a dedicated hi-fi setup or a multi-purpose audio build, this driver adapts seamlessly to diverse applications.

Technically, the CHR-90 Champ features a total Q factor (Qts) of 0.36, ensuring controlled, articulate bass response even in compact cabinets. With a resonance frequency (Fs) of 44.3 Hz, an equivalent volume (Vas) of 26.14 litres, and a maximum linear excursion (Xmax) of 7 mm, it delivers robust low-end performance. The sensitivity of 89.36 dB (SPL 1m/2.83V) and low voice coil inductance (Le) of 0.0912 mH contribute to efficient, distortion-free operation. Mechanical (Qms) and electrical (Qes) Q factors of 2.4647 and 0.4212 respectively further enhance transient accuracy.

In summary, the CHR-90 Champ offers a refined blend of compact design and full-range fidelity, making it an excellent foundation for high-quality audio projects.
