Overview

The Ashby-8C self-powered, ceiling-mounted loudspeaker provides wide coverage and low distortion, even at high sound levels, for applications that require accurate music reproduction and intelligible voice. The Ashby-8C is ideal for applications that require a deeper low-end and higher SPL. It offers sonic performance beyond other in-ceiling loudspeakers of comparable size.

The Ashby-8C is engineered to the same award-winning standards as all Meyer Sound IntelligentDC™ loudspeakers. With on-board amplification and sophisticated signal processing, the Ashby-8C exhibits the flat frequency and phase response for which Meyer Sound loudspeakers are known.

The Ashby drivers are designed and manufactured at the Meyer Sound factory in Berkeley, California. The 0.75-inch metal-dome tweeter is concentrically mounted over an 8-inch cone driver in an innovative configuration that maximizes the surface of the wave guide.

With an incredibly smooth, consistent 100° coverage, fewer loudspeakers can cover a larger area, reducing system cost while maintaining the highest sound quality.

The Ashby-8C requires an external MPS IntelligentDC power supply. These units distribute DC power and balanced audio to Ashby loudspeakers or other Meyer Sound IntelligentDC loudspeakers. Composite multi-conductor cables (e.g., Belden® 1502) can deliver both DC power and balanced audio from a single Phoenix™ 5-pin male connector.

The MPS-488HP can power up to 16 Ashby-8C loudspeakers (2 per channel) and can connect to Meyer Sound’s RMS remote monitoring system. The MPS-482HP can power up to 4 Ashby-8C loudspeakers (2 per channel). Using a Meyer Sound IntelligentDC external source power supply has several advantages:

  • Eliminates the need to use conduit (Class 2 wiring)
  • Allows longer, lighter-gauge cable runs
  • Preserves the advantages of self-powered systems with even more flexible installation options

Housed in an integrated zinc-plated steel-back can to meet commercial fire codes, the Ashby-8C can be flush-mounted in ceilings using a low-profile grille that blends discretely into any decor. Meyer Sound offers accessories specifically designed to install Ashby loudspeakers into a variety of ceiling environments including a pendant, a C-ring with a bridge for suspended ceilings and a new construction bracket.
