Get a free HFT Speaker Kit Mk II!

($895.00 value)

Black Box Carbon

Eliminate room congestion and unlock your system’s true potential with the Black Box Carbon, a recent revision of our our revolutionary low-frequency resonator. The Black Box Carbon uses mathematically derived sympathetic resonance to correct phase at fundamental frequencies like 20Hz, automatically clearing its harmonics across the entire spectrum. Featuring advanced carbon fiber and aluminum chassis construction that dissipates mechanical vibration while preserving resonator purity, plus precision bronze contact inserts for optimal stacking performance, the Black Box Carbon delivers dramatically tighter bass, enhanced resolution, and natural presentation that lets pure music flow freely through your room. Stack multiple units or combine with original Black Boxes for even greater impact, transforming your listening space from acoustic obstacle into musical ally that finally reveals the spatial accuracy and detail your system was designed to deliver.

MSRP - $2,395

HFT Speaker Kit Mk II

HFT Speaker Kit MkII dramatically improves your speakers ability to disappear and enable a sonic presentation that is tonally accurate, with the spatial realism and emotional immediacy the music was meant to convey in a way that goes beyond what we believed possible. With six different types of precisely tuned HFT (up from three) featuring faster activation and tighter phase alignment, the breakthrough lies in a new controlled asymmetric deployment where each of the seven positions is independently tuned to complement the others in ways symmetric placement never could achieve. The result transcends what seemed possible: instruments bloom with greater body and truth, vocals hang with stunning presence, and recordings scale effortlessly from intimate ensembles to large orchestras—delivering not just better sound, but sound that feels completely right.

The HFT Speaker Kit MkII isn’t an upgrade—it’s a complete revolution that reconstructs your soundstage’s phase structure from the ground up.

MSRP - $895 / 14 pack
