Full-Range 2-Way Acoustic Performance
The OSD ACE600 combines an acoustically damped 6.5-inch polypropylene woofer with a 3/4-inch PEI dome tweeter. This 2-way driver configuration delivers natural vocal reproduction, clear dialogue, and tight musical bass across a wide 50Hz to 20kHz frequency spectrum.
Moisture-Resistant Polypropylene Cone
Constructed from high-grade polypropylene with a long-lasting rubber surround, the woofer resists moisture and temperature fluctuations. This makes the ACE600 exceptionally well suited for high-humidity residential environments such as covered patios, spa bathrooms, and open kitchens.
Architectural Trimless Magnetic Grille
The ACE600 features OSD Audio's Edgeless architectural profile, replacing traditional wide plastic bezels with a slim, magnetically attached steel mesh screen. The grille sits flush against drywall and can be painted to match your interior ceiling color perfectly.
Simple & Secure Dog-Ear Clamping System
Equipped with four rotating dog-ear mounting clamps, the ACE600 locks securely into drywall cutouts with standard screwdriver turns. High-tension gold-plated push terminals ensure firm, corrosion-resistant speaker wire connections up to 14 AWG.
