CARBON15A

A woofer and compression driver built for power.
The CARBON15A pairs a 15-inch woofer with a 1.35-inch compression driver, delivering a total amplification power of 1500W RMS (3000W peak), a maximum SPL of 131 dB, and a frequency response spanning 45 Hz to 20 kHz.

A compression driver built for clarity.
The horn, with its extended dispersion control zone, houses a polymer-diaphragm compression driver rather than a titanium one, for noticeably clearer, more transparent highs. Dispersion holds at 90° x 70° at 10 kHz, keeping coverage even across the whole listening area.

A nitrogen-injected composite cabinet, lighter and stronger.
The CARBON15A’s enclosure is nitrogen-assisted injection molded — a process that cuts weight while adding 20% more rigidity than standard plastic molding. In practice, the resulting composite behaves somewhat like wood grain, its internal structure adding stiffness without piling on mass. The payoff is a sturdier cabinet and cleaner sound reproduction, with fewer parasitic resonances than a standard injection-molded plastic enclosure.

Connectivity and setup.
Two Line/Mic inputs on COMBO XLR/Jack connectors, auto-switching to whatever’s plugged in, plus the Bluetooth input. One XLR line output sends the signal onward to another speaker, a mixing console, or an amplification system, also available as a Bluetooth TWS stream. Switching power supply, 220-240V AC 50Hz, with a 1.80m Seetronic power cord included.

A shape built with stage monitoring in mind too.
Its asymmetric shape, with angled cut sides, lets the CARBON15A double as a stage monitor (wedge), alongside standard pole-mounted use. Full-face metal grille, 3 handles (side, top, bottom), a 36mm pole socket, 3 M10 rigging inserts, and 8 rubber feet (4 on the bottom, 4 on the sides) for a stable footing on the ground or on its side.

A full DSP, controlled from the speaker or remotely.
Fanless Class D amplification (1000W RMS for lows, 500W RMS for highs) runs through a DSP you can access from the 2.4-inch color front display or the CARBONcontrol app (iOS and Android). On the menu: mode (Normal, Live, Club, Speech), position (pole, monitor, stand), delay adjustable up to 100 m, a high-pass filter from 20 to 150 Hz, and a ducking function with selectable source channel, threshold, attenuation, and release time. Per-channel EQ, treble, and bass, with Live, Vocal, or Custom presets.

Locking and usage tracking.
Independent 4-digit lock codes for the LCD screen and the app, useful for keeping settings from drifting mid-show. A usage-hour counter, viewable and resettable from the menu.

Firmware Information.

Firmware version 1.0.4 comes preinstalled on CARBON12A and CARBON15A units currently in stock. It cannot be installed on earlier versions.

However, differences in firmware between two speakers have no impact on TWS Bluetooth compatibility, app functionality, or audio settings.

New features in firmware version 1.0.4:

• LCD Key — locks the display and DSP (4-digit code)
• APP Key — locks the application (4-digit code)
• Time Clear — usage counter and reset

Bluetooth, and one app for the whole CARBON lineup.
Bluetooth (2402-2480 MHz band, +8 dBm / 6.31 mW) covers everything from simple streaming to full app control. TWS pairs two CARBON15A units in stereo (one speaker set to link, the other to secondary), with a one-tap left/right swap or mono switch. The CARBONcontrol app handles every model in the CARBON range from one interface: each speaker or sub in your rig appears on its own, with remote access to its complete set of DSP settings.
