Overview
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.
