Tannoy AMS 6ICT LS Loudspeaker
Technical Data Sheet
Product Description
Designed for a wide variety of sound reinforcement applications, the Tannoy AMS 6ICT LS is a high-performance, ultra-compact surface mount weather-resistant loudspeaker specifically designed to UUMW standards for use in mission-critical life safety applications.
This is a full-bandwidth loudspeaker designed for commercial, professional, and residential applications where environmental durability and high-quality sonic performance are required. Indoor or outdoor, these speakers are ideally suited to stereo or monaural background or foreground music systems in applications such as theme parks, retail premises, restaurants and cafés, corporate audio visual, residential developments, and houses of worship.
Equipped with Tannoy's unique and exclusive point source ICT™ 165 mm (6.50") drive unit, the AMS 6ICT LS delivers an acoustic performance of outstanding clarity, definition, and detail. The point source configuration of the Tannoy ICT™ driver's mid-bass and tweeter sections ensures a wide and controlled dispersion for optimum coverage, while avoiding the massive loss of energy in the vertical plane at the crossover frequency inherent in two-way discrete designs. The ICT (Inductive Coupling Technology) drive unit also addresses two common component failures in background music and sound reinforcement systems: tweeter and crossover reliability. The use of a wireless electromagnetic tweeter means no crossover is required in the design, ensuring exceptional reliability and suitability for applications where constant heavy usage is the norm. This aluminum high-frequency dome has a deep-drawn skirt that sits inside the low-frequency voice coil in the same magnetic gap. The skirt acts as a single shorted turn induced with high-frequency information generated by the low-frequency voice coil, which receives a full-bandwidth signal. The mineral-loaded polypropylene cone material and nitrile rubber surround further enhance durability and long-term reliability.
The AMS 6ICT LS is UL-1480, category UUMW when installed with a junction box (on-wall or in-wall). It is for use with non-DC supervised systems.

Performance Measurements
1 m On-Axis Frequency Response
This graph shows the loudspeaker's sound output level (in dB) across a range of frequencies (from 10 Hz to 10 kHz) when measured 1 meter away on-axis. The response is relatively flat, indicating consistent sound reproduction across the audible spectrum, with a sensitivity of approximately 90 dB at 1 kHz.
Anechoic Frequency Response
Similar to the on-axis response, this graph illustrates the frequency response measured in an anechoic environment, confirming the loudspeaker's sound output characteristics without room reflections.
Impedance vs. Frequency
This graph plots the loudspeaker's electrical impedance (in ohms) against frequency (from 10 Hz to 10 kHz). It shows a peak impedance around 100 Hz (approximately 25 ohms) and then settles to a nominal impedance of 16 ohms for most of the frequency range, indicating its electrical load characteristics.
Off-Axis Frequency Response
These graphs display the frequency response measured at various angles off the loudspeaker's central axis (0, 10, 20, 30, and 40 degrees). They demonstrate how the sound quality and level change as the listener moves away from the direct listening position, illustrating the dispersion pattern.
Beamwidth vs. Frequency
This graph illustrates the beamwidth (in degrees) of the loudspeaker's sound dispersion as a function of frequency (from 100 Hz to 10 kHz). It shows that the sound dispersion is very wide at lower frequencies and gradually narrows as the frequency increases, indicating directional control.
Directivity Index (DI)
This graph shows the Directivity Index (DI) in decibels (dB) versus frequency (from 100 Hz to 10 kHz). The DI quantifies how well the loudspeaker concentrates sound in a particular direction. The graph indicates that the DI increases with frequency, meaning the sound becomes more directional at higher frequencies.
Polar Plots (1/3 Octave)
These polar plots provide a detailed visualization of the loudspeaker's directional sound output at specific frequencies (e.g., 100 Hz, 250 Hz, 630 Hz, 1 kHz, 4 kHz, 10 kHz). Each plot represents a 360-degree view around the speaker, with concentric rings indicating sound level (dB) and radial lines indicating angle. They visually confirm the beamwidth and dispersion patterns described in the previous graphs.
