DRIVER TECHNOLOGY
The Castor Bass edition uses the same dual 10 mm stacked dynamic drivers as the Harman model—one woofer dedicated to sub-bass and one driver for mids/highs. Powerful N52 magnets and a dual-cavity structure give strong output and fast transients. What sets this version apart is its tuning system: specialized filters and damping increase low-frequency sensitivity by over 10 dBunlocking deepsubwoofer-like bass while keeping mids and highs clean. The 3D-printed internal frame stabilizes both drivershelping maintain clarity even at high volume. DIP switches allow up to 16 profilesletting you fine-tune bass and treble to taste.
TUNING PHILOSOPHY
This edition is built for bass enthusiasts. The default signature is a bold U-shape with massive sub-bass and mid-bass boostwhile mids and highs stay aligned with the Harman curve above 1 kHz. The bass driver delivers powerful rumble without overwhelming vocals thanks to the dual-driver separation. Treble remains smooth and clearavoiding sharpness. Overallthe Castor Bass version provides a thrilling “club-style” low end while maintaining musical claritymaking it ideal for EDMhip-hopand bass-heavy modern genres.
