The Delta 12A is a high-performance active speaker designed to deliver pristine audio clarity and powerful output for live sound, DJ setups, and professional installations. Featuring a 12″ woofer paired with a premium 1.7″ titanium compression driver, it produces a balanced and dynamic sound across the spectrum. With a frequency response of 55Hz – 20kHz, the Delta 12A ensures deep lows, detailed mids, and sparkling highs, making it versatile for both music playback and speech reinforcement. Its 132dB maximum SPL guarantees exceptional volume without compromising sound quality, even in demanding environments.
Powered by a robust 700W Class D amplifier and a digital bi-amp system with linear phase, the Delta 12A combines efficiency with precision. The advanced amplification technology reduces distortion while maintaining headroom, ensuring consistent performance at any volume level. Rugged yet refined, this speaker is built to meet the needs of professionals who demand both reliability and superior sound. Whether on stage, in the studio, or at an event, the Delta 12A delivers the power and clarity needed to elevate any performance.
A digital bi-amp speaker uses two separate amplifiers: one for the low-frequency driver (woofer) and one for the high-frequency driver (tweeter). The signal is split digitally (in the DSP—Digital Signal Processor) before amplification, ensuring precise control over crossover points, EQ, and dynamics for each driver.
The linear phase aspect means the speaker uses FIR (Finite Impulse Response) filters in its DSP to ensure that all frequency components of the sound arrive at the listener in phase—resulting in transparent, time-coherent sound reproduction. This improves clarity, stereo imaging, and impulse response without introducing phase distortion, unlike traditional IIR filters.
