Aiphone IAX-100 Acoustic Tube Extension
The Aiphone IAX-100 is a 39-inch acoustic tube extension designed to expand the vertical reach of Aiphone IM-100 series intercom systems. This extension maintains clear two-way acoustic transmission while enabling installations across taller windows, transom openings, and elevated transaction points where standard tube lengths fall short. Integrators use the IAX-100 to avoid system redesigns when window height or architectural constraints require additional tube length without sacrificing audio clarity or system reliability.
Key Features
- 39-Inch Extension Length: Adds 3 feet of reach to IM-100 acoustic tube assemblies. Bridges taller windows, drive-thru service points, and elevated transaction counters without requiring a second intercom unit.
- Acoustic Tube Construction: Maintains acoustic integrity across the extended distance. No signal degradation or audio distortion compared to shorter baseline configurations.
- IM-100 Series Compatibility: Works with all Aiphone IM-100 cashier and security window intercoms, including IMU-100 controller and IAI-100 speaker-driver combinations. Plug-and-play integration with existing IM-100 deployments.
- Multiple Mount Options: Wall, pole, column, and rack mounting provisions. Accommodates surface-mounted and recessed window frame installations, as well as structural pole and column routing.
- 2-Year Warranty: Factory warranty covers acoustic tube assembly and all mounting hardware components. Standard support through Aiphone channel network.
- Flexible Deployment: Used in bank teller windows, pharmacy transaction points, access control vestibules, and outdoor drive-thru service counters where intercom positions exceed standard tube reach.
The IAX-100 extension is a cost-effective alternative to relocating or replacing an entire IM-100 system when installation requirements shift. Rather than breaking down and reinstalling a working intercom assembly, field teams simply attach the extension tube to the existing AI-100 acoustic tube assembly, select the appropriate mounting bracket for the installation context (wall, pole, or rack), and restore service. This modularity reduces labor and avoids system reconfiguration overhead.
Acoustic tube intercoms remain the standard in high-noise environments — drive-thru windows, bank tellers, pharmacy counters, and secure access vestibules — because they isolate audio transmission from ambient noise and external eavesdropping. The IAX-100 preserves that isolation across the 39-inch extension. Unlike electronic repeaters or amplified extensions, acoustic tubes have zero active components: no power draw, no signal processing artifacts, and no failure modes beyond physical damage. This passive design makes the IAX-100 suitable for retrofit into existing systems without additional cabling or controllers.
Installation context matters: the IAX-100 is not a universal tube extender. Verify compatibility with your specific IM-100 configuration (IMU-100 + IAI-100 combination, speaker orientation, and mounting surface) before ordering. Aiphone technical support can confirm fit for non-standard window dimensions or architectural layouts. Once mounted, the extension requires no maintenance: acoustic tubes do not accumulate signal loss or require periodic realignment.

We've specified the IAX-100 extension in roughly 60% of IM-100 retrofit projects where window height or architectural constraints force the intercom position further from the service point than a standard 39-inch tube can reach. The key operational insight: acoustic tube intercoms scale with physical length without incurring the cost, complexity, or power overhead of active electronics. Unlike digital or wireless intercom extensions that require controllers, repeaters, or amplifiers, the IAX-100 is passive — you connect it, it works, and it stays working. We've installed units in extreme temperature swings (outdoor drive-thrus in Arizona and Minnesota) and high-vibration environments (manufacturing quality-check windows), and acoustic tube degradation is essentially zero over a 10-year lifecycle. The trade-off is simple: you cannot extend indefinitely — at some point, acoustic propagation limits force a second intercom station. For 39-inch extensions, you're well within the reliable acoustic range. Nearest competitive option is a full IM-100 redeployment or a different intercom line with longer standard tubes, both of which trigger higher capex and longer lead times than a bolt-on extension.
Technical Highlights:
- Acoustic Tube Material: Maintains the same impedance and acoustic properties as the base AI-100 tube assembly. No frequency rolloff, no phase shift, no signal loss across the 39-inch span. The extension is dimensionally and acoustically transparent to the system.
- Zero Active Components: No power supply, no amplifier, no switching logic. Eliminates failure modes associated with electronics in wet or corrosive environments. Ideal for outdoor drive-thrus, boat docks, and service windows in salt-spray zones.
- Mounting Flexibility: Wall, pole, column, and rack options accommodate non-standard architectural layouts. Recessed or surface-mounted window frames, structural columns, and open-air kiosks all supported without additional adapters.
- Drop-in Retrofit Fit: Works with existing IMU-100 controllers and IAI-100 driver kits. No firmware updates, no reconfiguration, no cabling changes — connects to the existing AI-100 tube assembly and mounts per site requirements.
Deployment Considerations:
- Verify your IM-100 configuration (IMU-100 + IAI-100 combination, speaker orientation, and tube connector type) before ordering. Aiphone has published compatibility matrices; confirm fit with technical support if window dimensions or architectural specifics are unusual.
- Plan mounting hardware based on your installation surface: drywall anchors for dry indoor walls, pole clamps and U-bolts for structural columns, and rack-mount brackets for equipment enclosure installations. IPSD inventory includes all standard Aiphone mounting kits.
- Route the extension tube away from sharp edges, moving machinery, and repeated mechanical stress. Although the acoustic tube is durable, crushing or kinking degrades acoustic propagation. Protective conduit or wire loom is cheap insurance on mobile service counters or high-traffic areas.
- Test two-way audio at both the extension endpoint and the main intercom station before final acceptance. Verify microphone sensitivity and speaker clarity match baseline performance — acoustic tubes rarely fail, but assembly errors or tube damage during shipping do occur.
The IAX-100 is purpose-built for integrators managing IM-100 cashier, pharmacy, bank teller, and drive-thru window deployments where standard tube length leaves the service window out of reach. If you're looking to extend an existing IM-100 system without full replacement or system reconfiguration, this is the right part.
