Amie-Sub Loudspeaker and Dimensions
The linear, self-powered Amie-Sub compact subwoofer offers outstanding sonic characteristics, such as clean, punchy transients and excellent phase coherence with impressive low-frequencies down to 22 Hz in a compact cabinet.
The Amie-Sub was specifically designed to be the perfect companion for Amie precision monitors—creating a complete system by extending the system frequency response down to the lower limit of the audible range with easy integration in multi-channel configurations.
In addition, due to its performance and versatility, the Amie-Sub is equally suited to complement other Meyer Sound loudspeakers, such as HMS-5, HMS-10, HMS-12, and HMS-15 in immersive surround applications or across other more general applications with UltraSeries loudspeakers.
Extensive research and measurements resulted in the creation of Amie-Sub integration modules to produce consistent behavior across multiple configurations and environments.
The optional integration modules enable the Amie-Sub to excel at working in any multichannel configuration, creating a perfectly balanced and easy-to-set-up system with up to 7 Amie precision monitors.
The 2.1 integration module features 2 input channels using XLR connectors, while the 7.1 module features industry-standard multi-pin DB-25 and can be used in 5.1 or 7.1 configurations with third-party, high-quality, 8-channel, DB-25-to-XLR cables.
The integration modules feature bass management processing as well as a dedicated phase-matched .1 input for the LFE channel with selectable +10 dB boost to meet a variety of standards.
The Amie-Sub has an operating frequency range of 22–160 Hz and a linear peak SPL of 124.5 dB with crest factor >11.5 dB, measured in half-space at 4 m and referred to 1 m using M-noise.
The Amie-Sub includes a single 15-inch, low distortion, long-excursion cone driver. The bass reflex cabinet employs an optimized port design for high efficiency and low port distortion. Its slanted connector panel facilitates flush-mounting the cabinet against wall surfaces, reducing the required installation depth to 19 inches including connectors.
The cabinet houses a Class D power amplifier and signal processing includes crossover, driver protection, and frequency and phase correction.
The Intelligent AC™ power supply provides automatic voltage selection, EMI filtering, soft current turn-on, and surge suppression.
Meyer Sound builds the Amie-Sub cabinet from premium birch plywood coated with a durable, slightly textured finish and includes a stamped-steel grille to protect the drivers. A grille frame with black cloth that mounts on top of the steel grille is optionally available.
The Amie-Sub comes standard with two 3/8-inch by 16 mounting points on each side for use with the optional MUB-Amie-Sub U-bracket for mounting the subwoofer from ceilings.

Notes
Loudspeaker system predictions for coverage and SPL are available in Meyer Sound’s MAPP System Design Tool.
Recommended maximum operating frequency range. Response depends on loading conditions and room acoustics.
Measured in half-space with pink noise at 4 m, 1/3-octave frequency resolution.
Linear Peak SPL is measured in half-space at 4 m referred to 1 m. Loudspeaker SPL compression measured with M-noise at the onset of limiting, 2-hour duration, and 50 °C ambient temperature is <2 dB.
M-noise is a full bandwidth, (10 Hz–22.5 kHz) test signal developed by Meyer Sound to better measure the loudspeaker’s music performance. It has a constant instantaneous peak level in octave bands, a crest factor that increases with frequency, and a full bandwidth Peak to RMS ratio of 18 dB. The presence of a greater-than (>) symbol with regard to crest factor indicates it may be higher depending on EQ and boundary loading.
Pink noise is a full bandwidth test signal with Peak to RMS ratio of 12.5 dB.
B-noise is a Meyer Sound test signal used to ensure measurements reflect system behavior when reproducing the most common input spectrum, and to verify there is still headroom over pink noise.
The DB-25 multi-pin connectors are wired to an analog pinout that has become the standard in the audio industry; it is sometimes referred to as the Tascam® DTRS pinout.
Peak power based on the maximum unclipped peak voltage the amplifier will produce into the nominal load impedance.
AC power cabling must be of sufficient gauge so that under burst current rms conditions, cable transmission losses do not cause the loudspeaker’s voltage to drop below the specified operating range.
