ATEN 4-INCH Coaxial Ceiling Loudspeakers (one Pair) - AS104

ATEN AS104 4-Inch Coaxial Ceiling Loudspeaker Pair

The ATEN AS104 is a coaxial ceiling loudspeaker sold as a matched pair, built for commercial AV installations where clean overhead audio distribution and straightforward wiring are priorities. The AS104 uses a 20mm PEI (polyetherimide) dome tweeter in a coaxial configuration — meaning the high-frequency driver is concentrically aligned with the woofer — which produces a more coherent soundstage across the listening area compared to offset two-way designs. The white speaker grille and baffle are paintable, so the fixture blends with ceiling finishes without requiring custom orders.

Key Features

• 20mm PEI Dome Tweeter: Polyetherimide dome construction handles extended high-frequency reproduction without the thermal degradation that affects softer dome materials in continuous-use commercial environments — a practical advantage for conference rooms and corridors running audio all day.
• 5.08mm Euroblock Connector Audio Input: The Euroblock (phoenix-style) connector simplifies field termination — no soldering, no proprietary plugs. Installers can wire directly from an amplifier or distribution system using standard two-conductor cable, which keeps labor time down on multi-zone installs.
• Paintable White Grille and Baffle: Both the speaker grille and baffle accept standard latex or acrylic paint, so the AS104 can be color-matched to virtually any ceiling without specialty finishes or ordering factory color variants.
• CE, WEEE, and RoHS Certified: Compliance with CE marking, WEEE (Waste Electrical and Electronic Equipment), and RoHS (Restriction of Hazardous Substances) confirms the AS104 meets European regulatory requirements — relevant for enterprise deployments with environmental procurement mandates.
• Storage Temperature Range -20°C to 60°C: Wide storage tolerance means units can be staged in unheated warehouses or hot staging areas without risk of degrading the driver materials before installation.
• Sold as a Matched Pair: The AS104 ships two units per carton. Purchasing in pairs keeps channel-matched stereo zones or symmetric mono coverage drops consistent — no sourcing mismatches between left and right positions in a zone.

Integration and Compatibility

The 5.08mm Euroblock input on the AS104 is a standard interface compatible with commercial amplifiers and distribution amplifiers from most major AV manufacturers. In commercial paging, background music, or conferencing audio distribution systems, Euroblock termination is the norm — no adapters needed. Pair the AS104 with a AV distribution system or a multi-zone amplifier for scalable overhead audio coverage. Browse the full ATEN product catalog for complementary AV infrastructure. For projects involving integrated security and AV, explore IP camera systems that can be co-deployed in the same ceiling grid. If you are planning a larger AV rollout, consult a recording and monitoring infrastructure guide for system-level design considerations.

Frequently Asked Questions

Q: Is the AS104 sold as a single unit or a pair?

A: The AS104 is sold as a matched pair — two loudspeakers per carton. Plan your zone quantities accordingly (each carton covers one stereo pair or two mono drops).

Q: What type of connector does the AS104 use for audio input?

A: The AS104 uses a 5.08mm Euroblock (phoenix-style) connector. This is a tool-terminated screw-clamp interface standard on commercial amplifiers and AV distribution equipment — no soldering or proprietary adapters required.

Q: Can the AS104 grille and baffle be painted to match my ceiling?

A: Yes. Both the grille and baffle are specified as paintable. Standard latex or acrylic ceiling paint adheres without requiring primer on most commercial ceiling surfaces.

Q: What certifications does the AS104 carry?

A: The AS104 carries CE marking, WEEE compliance, and RoHS certification — meeting European regulatory requirements for commercial electronics.

Q: What are the storage temperature limits for the AS104?

A: ATEN specifies a storage temperature range of -20°C to 60°C (-4°F to 140°F), so units can be staged in unheated or warm environments without damaging the drivers.

Marty Allison

The AS104 is a straightforward ceiling loudspeaker pair — what stands out in my experience is how much the 5.08mm Euroblock connector simplifies field wiring on multi-zone commercial installs. On a typical conference floor or corridor audio distribution project, the ability to terminate directly from 16AWG two-conductor cable into a screw-clamp connector — without soldering or crimping proprietary plugs — cuts per-drop labor time meaningfully when you are hanging 20 or 30 units across a building.

Technical Highlights:

• PEI Dome Tweeter: Polyetherimide is a thermally stable engineering polymer — it holds shape and acoustic properties under the sustained heat loading of a ceiling plenum environment better than soft-dome materials in continuous-use commercial settings.
• Paintable Grille and Baffle: Both surfaces accept standard ceiling paint. On tenant improvement projects or white-box commercial builds, this eliminates the need to special-order color variants or install aftermarket grille covers.
• CE/WEEE/RoHS Certification: For enterprise buyers with environmental procurement policies or EU-bound deployments, the AS104 ships with the documentation trail those compliance requirements demand.

Deployment Considerations:

• The Euroblock input requires a compatible amplifier or distribution amp with matching 5.08mm pitch terminals — verify your amplifier's output connector pitch before purchasing to avoid needing adapter blocks on site.
• Published specs do not include wattage handling, impedance, frequency response, or coverage angle — confirm these with ATEN's full datasheet before finalizing amplifier matching and zone coverage layout for your specific space.

The AS104 is a practical fit for conference rooms, open-plan office zones, or commercial corridor background audio where a clean ceiling appearance, simple Euroblock wiring, and paired procurement are the primary requirements.
