New Meyer Sound ULTRA-X20 Loudspeaker and USW-112P Subwoofer Maximize Versatility



ULTRA-X20 Loudspeaker


At ISE 2020 in Amsterdam, Meyer Sound is introducing two new compact, self-powered loudspeakers that leverage a new generation of technologies to provide exceptional versatility for covering a wide range of installed and portable applications.

ULTRA-X20 Compact Point Source Loudspeaker

The new ULTRA-X20 compact point source loudspeaker is a junior-sized version of the ULTRA-X40 loudspeaker introduced at last year’s ISE show. It offers the same design principles and technologies but with smaller drivers in a lighter and more compact package.

The ULTRA-X20 incorporates two 5” cone drivers, one 2” diaphragm compression driver, and a rotatable 110°x 50° horn in a coaxial configuration. Power comes from a three-channel Class D amplifier with sophisticated DSP, with everything fitted inside a compact cabinet that measures 7.5” / 19.5 cm wide by 19.04” / 48.4 cm high by 8.6” / 21.8 cm deep and weighs only 26 pounds / 11.8 kg. Preliminary performance specifications give an operating frequency range of 60 Hz to 18 kHz, phase response of ±45° (100 Hz – 16 kHz) and linear peak SPL of 123.5 dB measured with M-Noise.

“The ULTRA-X20 is a breakthrough in power-to-size ratio,” says Pablo Espinosa, Meyer Sound’s Vice President, and Chief Loudspeaker Designer. “It is 30 percent smaller and 7 percent lighter than our UPJunior loudspeaker yet it offers equivalent output power and — thanks to the new coaxial design — much more consistent pattern control below the crossover point.”

The ULTRA-X20 can be ordered with any one of three connector panel options. The two AC powered versions both have looping Powercon connectors with choice of 3-pin XLR for audio or 5-pin XLR for audio and RMS remote monitoring. Another version is offered for integration in IntelligentDC systems (audio and remote DC powering on a single cable) with a 5-pin Phoenix connector.

Two additional variants are offered, identical except for the patterns of the rotatable horn: ULTRA-X22 (80°x 50°) and ULTRA-X23 (110°x 110°).

Transport, mounting and rigging options are offered for every conceivable application. A carry handle is standard but easily removable. Two integral M8 rigging points on each end enable use of a pole mount, single point hang, wall or ceiling mounting, or yoke mount in horizontal or vertical orientation at any angle. Four additional M6 points on the heatsink are compatible with most industry-standard wall mount brackets. A weather protected version is available with sealed connectors that eliminate the need for rain hoods.

For extended low frequency power, the ULTRA-X20 may be paired with the new USW-112P subwoofer, the 750-LFC low-frequency control element or USW-210P subwoofer. The ULTRA-X20 is natively aligned with the 750-LFC to maximize ease of use in portable applications to allow rapid deployment with minimal effort.


USW-112P Subwoofer


USW-112P Subwoofer

The USW-112P compact subwoofer packs robust low frequency performance into a slender, self-powered package measuring less than 12” / 30 cm deep. The slanted connector panel allows placement flush to walls, in vertical or horizontal orientation, making the USW-112P an ideal choice when stage or installation space is limited.

The USW-112P houses a single 12” long-excursion driver along with a highly efficient class D amplifier and advanced digital signal processing. The cabinet design features a low velocity port, based on the USW-210P, with optimized tuning for linear response and low distortion. Preliminary performance specifications include a linear peak output (measured with M-Noise signal) of 123 dB SPL across an operating frequency range of 35 Hz to 140 Hz. Phase response measures ±30° from 45 Hz to 120 Hz. The subwoofer measures 23.50” / 59 cm high by 13.50” / 34.3 cm wide x 11.95” / 30 cm deep. Weight is 47 pounds / 21.3 kg.

Versions of the USW-112P are offered with either direct AC powering or for integration into systems using IntelligentDC, Meyer Sound’s technology for supplying both DC power and audio from a remote, rack-mount unit over a single cable. Optional facilities also are offered for Meyer Sound’s RMS system for comprehensive remote monitoring.

The USW-112P is supplied standard with a removable carry handle and M8 rigging points on the top and bottom. A side-mounted, 35mm/M20 thread pole mount receptacle is available as an option. Using an M20 to M8 thread adapter, the USW-112P can be flown from a single eyebolt. An optional U-bracket facilitates mounting to a truss, ceiling or wall. A weather protected version uses sealed connectors (IP-X4 or higher rating), eliminating the need for rain hoods.

“The USW-112P is an extraordinarily versatile subwoofer,” says Espinosa. “With its shallow footprint and light weight, it can go anywhere and fit anywhere, from churches and clubs to restaurants and small theatres.”
