The cabinet is an aluminum die-cast enclosure tuned with a bass reflex port, delivering tight, high-speed bass that transcends its size. A bi-amplified D-class amplifier section drives the woofer with 30 W and the tweeter with 20 W. Low-frequency, tweeter level, and input gain switches let the user tailor the monitor to its acoustic environment and to the level of connected sources.

  • NF06

    The NF06 is a new near-field passive monitor speaker created using technology accumulated over many years of developing professional monitor speakers.
