OSD Audio ACE600ST Trimless 70V In-Ceiling Speaker

Trimless 6.5-inch In-Ceiling Speaker for 70V Distributed Audio

The OSD Audio ACE600ST is a trimless 6.5-inch in-ceiling speaker with a built-in 70V transformer, made for background music and announcements across several rooms or zones from one amplifier. It is a different model from the ACE600: the ACE600ST is a 70V commercial speaker sold singly, and it also has an 8 ohm setting.

A magnetic, paintable grille sits flush with the ceiling with no visible trim ring, so the speaker blends into the room. A 6.5-inch polypropylene woofer with a rubber surround and a 0.5-inch PEI dome tweeter keep voices and music clear and natural, not harsh like typical commercial speakers.

The transformer dial sets how much power each speaker takes (20W, 10W, 5W or 2.5W on 70V), so many speakers can share one long cable run without losing level. Dog-ear brackets lock it into the ceiling, and a cut-out template is included.

Best suited for:
Restaurants, offices, retail spaces, showrooms and homes that want distributed background music from a 70V amplifier. Sold individually.
