The Cinnamon Cassia loudspeakers offer high sensitivity and easy amplifier drive combined with true full-range performance. Furthermore, "full-range" immediately raises challenges: how to ensure correct bass reproduction in complex rooms?
This is why the Cassia speakers look as they do: pure dipoles (no traditional enclosure), controlled and matched directivity (every element works in unison in all directions), and adjustable low-frequency correction (adapting to any room). Yet they behave like traditional speakers with all complexity hidden inside.

The Cinnamon Cassia uses an 8" midrange driver (mid-coupler), horn-loaded AMT tweeter matched via phase-coherent low-order filter, and 2x 15" woofers in active configuration (2x 250 W amplifier with DSP frequency and phase correction) below 150 Hz. The specification is also impressive with sensitivity of 97 dB and frequency range spanning 25 – 30,000 Hz.
The bass signal is corrected and re-amplified by a transparent, high-headroom internal amplifier - but only in the bass region. Your amplifier still "leads" the bass, imparting its tonal character, but transmitting signal rather than power. Baffles are available in numerous finishes: hand-oiled natural birch plywood, approximately 50 natural exotic veneers, or any RAAL brand color (gloss, matte, or metallic). Each Cassia is handmade to individual order with lead time from approximately 3 months for traditional finishes.
