450W AK12Pro Portable PA Speaker Dual System 6 Channel Mixer 9 Effects Dual OTG

MTCEO AK12Pro is a flagship professional dual PA speaker system engineered for demanding live sound reinforcement, high-fidelity streaming, and versatile mobile performances. It delivers a commanding 450W+450W rated speaker power and 600W+600W amplifier power through premium acoustic components, including a full neodymium 75-core woofer and tweeter with fully imported aluminum flat wire assemblies. Housed in a robust cabinet featuring a 15mm front baffle and double-layer 12mm birch plywood sides, it produces a rich 45Hz–20kHz frequency response. The system integrates a 6-channel mixer with independent 3-band EQ, low-cut, and noise gate controls, alongside 9 independently controllable digital effects. Dual OTG ports enable direct live streaming, while Bluetooth, USB, and AUX inputs provide versatile connectivity. A high-capacity 21700 lithium battery (14.6V/35A) ensures up to extended operation for any event.

The AK12Pro is constructed with a strong emphasis on acoustic purity and structural rigidity. The speaker units utilize full neodymium magnetic structures and imported aluminum flat wire voice coils, which reduce moving mass while improving thermal dissipation and transient response. The cabinet is built with a 15mm front baffle and double-layer 12mm birch plywood side panels, minimizing unwanted resonance and delivering tight, controlled low-frequency reproduction. The integrated digital signal processing (DSP) system manages the 6-channel input section, offering independent 3-band EQ, adjustable low-cut filters, and noise gates to eliminate stage hum and feedback. The dual OTG interfaces provide direct digital audio extraction for live streaming without external sound cards. The power section is driven by a 21700 lithium battery pack managed by an internal BMS, ensuring stable voltage output and long cycle life.
