ADASTRA Two Way Low Profile Ceiling Speaker, 5.25 inch, 100V, 40W RMS
Discreet ADASTRA 5.25 inch ceiling speaker for 100V line or 8-ohm systems. 40W RMS, magnetic grille, easy ceiling installation.
The ADASTRA Two Way Low Profile Ceiling Speaker is engineered for discreet, high-fidelity audio installations in commercial and residential settings. Its sleek design features a flared baffle and a magnetic, frameless grille that sits nearly flush with the ceiling for a subtle, integrated appearance. This grille can be painted to match your décor, allowing the speaker to blend seamlessly into any interior design.
At its core is a high-performance 133mm (5.25 inch) woofer paired with a concentric 38mm (1.5 inch) tweeter, delivering a balanced frequency response from 85Hz to 20kHz. The speaker is versatile, operating on both 100V line systems and standard 8-ohm connections via a convenient rotary selector switch. For 100V line use, it offers five precise power tappings (2.5W, 5W, 10W, 15W, 20W), allowing for optimal volume zoning and distribution.
Installation is straightforward and secure, thanks to the integrated 'dog-ear' mounting brackets designed for fixing directly into suspended or false ceiling grids. With a mounting depth of just 84mm and a required cutout of 176mm, it fits neatly into standard ceiling cavities. The wide 160° dispersion angle ensures even sound coverage throughout the room, making it ideal for background music, public address, or multi-room audio systems where clarity and consistent volume are essential.
