The Citronic Megalith-12 is a 500W RMS active column array PA system combining a 12-inch subwoofer, an eight-driver curved array speaker and onboard mixing in one portable setup. Designed for mobile performers, entertainers and presenters, it provides a practical sound system for live vocals, backing tracks, speeches and event music without requiring a separate power amplifier.

The curved array combines four 4-inch midrange drivers with four 1-inch dome tweeters, supported by the dedicated 12-inch bass driver. An efficient Class-D amplifier and DSP control manage the speaker components, delivering a frequency response of 50Hz–18kHz and a maximum SPL of 126dB. The two-stage support column offers two height options, with through-connections between sections for straightforward assembly.

Four mic/line inputs accept XLR or 6.3mm jack connections, allowing microphones and external audio equipment to connect directly. An additional RCA or 3.5mm auxiliary input accommodates a wired playback source. Microphone EQ, echo/reverb effects and priority ducking provide useful control for singers and presenters, while an XLR line output allows connection to additional equipment.

Music playback is equally flexible. Play MP3 tracks from a USB drive, connect a laptop via USB-C or stream wirelessly from a compatible Bluetooth device. TWS pairing allows two Megalith systems to operate as a wireless stereo pair. A full-colour HD display and rotary encoder provide access to playback settings, a five-band graphic EQ and Music, Club, Speech and Flat sound presets.

High-impact moulded ABS enclosures make the system suitable for regular mobile use. A padded subwoofer slip cover and a padded bag for the column and array speaker are included, helping protect the components during transport and storage.
