OSD Audio ACE800ST 8" Trimless 70V In-Ceiling Speaker — 32W/16W/8W/4W Taps or 8Ω, 120W (Single)

The OSD Audio ACE800ST is a trimless 8" in-ceiling speaker built for flexible installation and reliable output. It supports 70V operation with an adjustable transformer featuring 32W, 16W, 8W and 4W selectable taps, and can also be used as an 8Ω driver — rated for 120W power handling. Audio is driven by a durable 8" polypropylene woofer that produces smooth low and mid-range response, paired with a 1" PEI dome tweeter for clear, articulate highs and vocal detail. The bezel-free, trimless grille blends flush with the ceiling for a discreet look, and included installation templates make mounting quick and straightforward.
