Atlas Sound SD72WV-KIT SD72 Speaker, 62-8 Baffle with Volume Control, CS95-8 Back Box, and 81-8R T-Bar Bridge Kit (Must be ordered in multiples of 12)

Product Overview

The Atlas Sound SD72WV-KIT is a complete 8-inch ceiling speaker kit built for 70V background music and paging system installations in commercial buildings. Each kit pairs the SD72WV dual cone in-ceiling speaker and 62-8 baffle with integrated volume control with a CS95-8 recessed back box and an 81-8R T-bar tile bridge, so integrators receive every component needed for a code-compliant suspended ceiling installation in one part number. The kit must be ordered in multiples of 12, which suits whole-floor and multi-zone commercial audio deployments. AtlasIED selected these components to work together out of the box, reducing bill-of-materials errors on distributed audio projects.

Product Description

At the heart of the kit, the SD72WV is a 25-watt, 8-inch (205 mm) dual cone speaker with a 10 oz (260 g) ceramic magnet and a curvilinear treated paper cone that lowers harmonic distortion in speech and background music playback. A full 1-inch copper voice coil on a black anodized aluminum former improves power dissipation for reliable long-term operation in commercial ceiling speaker systems. The factory-installed 25V/70.7V line matching transformer offers tap selections from 0.25 to 5 watts, letting system designers balance output levels across long 70V speaker runs without field wiring transformers. The 62-8 baffle includes an integrated volume control, giving facilities staff local level adjustment in individual offices, classrooms, or meeting rooms. The baffle is constructed of CRS with concealed mounting studs and uses standard mounting holes compatible with the majority of AtlasIED 8-inch tile bridges, mounting rings, and enclosures. The CS95-8 recessed round stacking enclosure ships with four 1/2"–3/4" combination conduit knockouts, four J-clips, and two flexible perforated mounting straps; its one-piece CRS construction is undercoated, patch-jute lined, and epoxy finished. The 81-8R tile bridge is built from 24-gauge CRS with an electrogalvanized rust-resistant finish and features a round cut-out sized for the CS95-8, distributing speaker weight across the T-bar grid for a secure drop ceiling speaker installation. With UL 1480 and UL 2043 safety listings, the assembly is suited to plenum airspace installations common in commercial buildings.

Frequently Asked Questions

Is the SD72WV-KIT compatible with standard 70V paging amplifiers?
Yes. The factory-installed 25V/70.7V line matching transformer connects directly to any 25V or 70V constant-voltage amplifier output, with taps from 0.25 to 5 watts per speaker.

Does the kit work in suspended T-bar ceilings?
Yes. The included 81-8R tile bridge spans standard T-bar grid rails and supports the CS95-8 back box and speaker assembly in drop ceiling installations.

Can this speaker be installed in plenum airspace?
The assembly carries UL 1480 and UL 2043 listings, which are the listings commonly referenced for speakers installed in air-handling spaces. Confirm requirements with your local authority having jurisdiction.

How does the integrated volume control work?
The 62-8 baffle includes a front-accessible volume control, allowing room-level attenuation of paging and background music without changes at the amplifier.

Why must this kit be ordered in multiples of 12?
AtlasIED packages the SD72WV-KIT in case quantities of 12, which matches typical per-floor speaker counts on commercial distributed audio projects.

What warranty applies to this kit?
AtlasIED covers the kit for 60 months from the date of purchase. Creation Networks provides pre-sale design assistance and post-sale support on all AtlasIED commercial audio products.
