Meyer Sound MM-10 Miniature Subwoofer
The Meyer Sound MM-10 miniature subwoofer delivers expanded low frequency for applications that require excellent audio quality from a compact system. Designed primarily as a companion to Meyer Sound’s MM‑4XP miniature loudspeaker, as well as the UP‑4XP ultracompact loudspeaker, both with IntelligentDC technology, the MM‑10 allows system designers to create full-range systems where space limitations are a concern.
The Meyer Sound MM-10 features an operating frequency range of 33 Hz to 228 Hz with a conservatively rated maximum peak SPL of 123 dB. The MM‑10 bass reflex cabinet houses a single 10-inch driver and a single-channel power amplifier complete with onboard processing, including a crossover, driver protection, and frequency and phase correction. The builtin crossover accepts full-range signals, facilitating basic daisy-chaining for signal distribution, eliminating the need for external crossovers in small setups.
The Meyer Sound MM-10 subwoofer is available from the factory in three models – the MM‑10XP, with IntelligentDC technology, MM‑10AC, and MM‑10ACX – each offering different internal configurations and audio and power connectors (which cannot be upgraded). The MM‑10XP model is powered by an external power supply, eliminating the need for wiring conduits while still preserving the advantages of self-powered loudspeaker systems. The unit’s onboard amplifier and signal-processing circuits were designed to store DC power and tolerate voltage drops, thereby accommodating light-gauge cables and lengthy cable runs. The MM‑10XP is available with either a Phoenix 5-pin male or sealed SwitchCraft EN3 male connector for receiving balanced audio and DC power. The EN3 connector is ideal for outdoor, all weather use.
MM‑10XPs require an external MPS‑488HP IntelligentDC power supply. The single-space 19-inch rack unit receives balanced audio from its XLR female inputs and routes the audio, along with DC power, to its channel outputs. The channel outputs – equipped with either Phoenix 5-pin male connectors or EN3 5-pin female connectors – can deliver DC power to up to eight MM‑10XP subwoofers at cable lengths of up to 150 feet with just 1 dB of loss in peak SPL using 18 AWG wire. The use of composite multiconductor cables (such as Belden 1502) allows a single cable to carry both DC power and balanced audio to the MM‑10XPs. Longer cable runs are possible for moderate applications that don’t drive the subwoofers to maximum output, or for installations with heavier wire gauges.
The MM‑10AC model is ideal for fixed installations and portable applications where AC power is readily available to power the unit. The MM‑10AC includes an internal power supply and locking powerCon 20 connectors for AC input and AC loop output (for powering additional MM‑10AC subwoofers). The MM‑10AC receives audio from an XLR female input, and also includes an XLR male loop output for daisy-chaining audio signals.
The MM‑10ACX model includes onboard DC power and audio routing for driving a pair of MM‑4XP miniature loudspeakers, or a single UP‑4XP ultracompact loudspeaker, effectively placing the MM‑10ACX at the heart of an extremely capable compact, full-range loudspeaker system. Three XLR female inputs are included for receiving audio independitely for the subwoofer and satellite loudspeakers. The two output connectors for the satellite loudspeakers are available with Phoenix 5-Pin male or EN3 5-pin female connectors. In addition, a two-channel signal can be patched to the satellite inputs and summed and routed to the subwoofer with the input select switch.
Other options for all Meyer Sound MM-10 models include the MUB‑MM10 U-bracket for mounting the subwoofer on ceilings and walls; weather protection, complete with rain hoods, for outdoor, all-weather use; and custom color finishes for installations and applications with specific cosmetic requirements.
