Studiomaster CORE 121 | 12in Sub - 124dB | 1000W RMS Curved Array PA System

StudioMaster Core 121 Black  (Studio Master Core121)

Portable Curved Array PA System

The Studiomaster CORE 121 combines a 12-inch active bass-reflex subwoofer, compact curved speaker array, four-channel mixer, Bluetooth connectivity, and 24-bit DSP in one portable PA system. Its 1000W RMS amplifier system, broad audience coverage, and cable-free connection between the subwoofer and array make it well suited to mobile DJs, live performers, presenters, and event production.

Studiomaster CORE 121 Competitive Differences

• Internally wired air-suspension speaker pole passes the audio signal from the subwoofer to the curved array without a separate speaker cable
• Curved array combines three 5-inch neodymium full-range drivers with nine 1-inch dome tweeters for 100° horizontal and 55° vertical coverage
• Integrated four-channel mixer provides mic, line, instrument, stereo RCA, and Bluetooth input options
• 24-bit DSP includes operating modes, EQ, limiter, output delay, channel metering, and mix-level control
• Dedicated subwoofer level control allows the low-frequency output to be balanced for different rooms and applications

Studiomaster CORE 121 Description

The Studiomaster CORE 121 uses a 12-inch low-frequency driver in a bass-reflex wooden enclosure to produce controlled, extended bass while occupying a compact 15.9 x 18.5-inch floor area. The subwoofer cabinet features a durable painted finish, large carrying handles, and an angled control panel that remains accessible during setup and operation.

The curved array is powered by a dedicated 300W RMS amplifier section and contains three 5-inch neodymium full-range drivers plus nine 1-inch dome tweeters. Its angled enclosure provides a wide 100° horizontal by 55° vertical coverage pattern, helping distribute vocals, music, and announcements across the audience area while limiting unnecessary vertical dispersion.

A built-in four-channel mixer allows microphones, line-level equipment, instruments, stereo sources, and Bluetooth devices to connect directly without requiring a separate mixing console. The 24-bit DSP interface uses a backlit LCD and single control for access to operating modes, three-band EQ, limiter processing, output delay, master level, sub level, and channel metering.

For faster assembly, the adjustable air-suspension speaker pole includes internal signal wiring. The array connects through the specially designed pole sockets, eliminating the exposed speaker cable normally required between a powered subwoofer and column or array cabinet. This streamlined design makes the system practical for mobile entertainment, live music, presentations, houses of worship, and compact venue sound reinforcement.
