Atlas Sound 510-4 – 4" Cylindrical Bidirectional Aluminum Baffle Enclosure

Product Overview

The Atlas Sound 510-4 is a cylindrical bidirectional baffle and enclosure for 4" loudspeakers, designed for corridor installations where ceiling or wall surface space is limited and sound must project in two directions from a single point. This aluminum surface mount speaker enclosure mounts to a standard 4" octagon electrical box and includes a circular canopy, mounting hardware, and a second grille for complete bidirectional coverage. Long-tail applications include corridor speaker enclosures for commercial buildings, bidirectional surface-mount speaker baffles for hallway audio systems, and aluminum speaker enclosures for healthcare and institutional facilities.

Product Description

The 510-4 is built on the same aluminum housing as the Atlas Sound 410 Series unidirectional baffle, with the addition of a circular mounting canopy and a second grille to enable sound projection in two directions from a single enclosure. This makes it particularly practical for corridor applications where a single speaker location needs to cover listeners approaching from both directions. The aluminum housing is patch-jute lined and undercoated to prevent mechanical and acoustic resonance, ensuring clear, audible speaker reproduction without rattles or coloration introduced by the enclosure itself. One grille per unit includes integrated studs for convenient speaker mounting. The housing's aluminum construction is non-rusting and durable in commercial environments. Installation attaches to a 4" (102mm) octagon electrical junction box (provided by others). The brushed satin aluminum finish blends with standard commercial architectural hardware. Speaker driver is sold separately. The 510-4 is UL listed. Overall dimensions: 6" diameter, 4 3/4" depth. Shipping weight: 1.17 lbs. A 60-month warranty applies.

Frequently Asked Questions

Q: Does the 510-4 include a speaker driver?

A: No. The 510-4 is an enclosure and baffle only. A compatible 4" loudspeaker driver must be purchased and installed separately.

Q: What electrical box does the 510-4 mount to?

A: The 510-4 mounts to a standard 4" (102mm) octagon electrical outlet box, which is supplied by the installer/contractor and is not included with the enclosure.

Q: How does the bidirectional design work?

A: The 510-4 includes two grilles — one on each end of the cylindrical enclosure — allowing the speaker driver to project sound in both directions simultaneously. This is particularly useful in corridor applications where coverage is needed in both directions from a single mounting point.

Q: What is the difference between the 510-4 and the 410 Series enclosure?

A: The 410 Series is a unidirectional (single-grille) surface baffle. The 510-4 adds a circular mounting canopy and a second grille for bidirectional sound dispersion from the same form factor.

Q: Can the 510-4 be painted?

A: The housing comes with a satin brushed aluminum finish. The grille can typically be painted with appropriate aerosol or spray paint to match interior finishes.

Q: Is this enclosure appropriate for plenum ceiling installations?

A: The 510-4 is designed for surface and corridor mounting to electrical boxes. For plenum-rated in-ceiling applications, refer to AtlasIED products specifically listed under UL2043.

Q: What warranty applies?

A: AtlasIED provides a 60-month (5-year) warranty from the date of purchase.
