Topping Professional MA4 Actives Speakers 2-Way 50W+25W 92dB 49Hz-20kHz White (Pair)
Topping's MA4s are two-way active monitor speakers combining 50W+25W Class D amplification with an acoustic architecture that does not use digital processing. Their design emphasises linearity, directivity control and the reduction of internal resonances, making them a solution that is equally suited to working environments and more open spaces.
Topping Professional MA4: Excellent directivity
For its tweeter, the MA4 incorporates an Opti-Wave waveguide that optimises the transition between midrange and treble frequencies. This design controls directivity and reduces phase shifts around the crossover frequency. The front panel features a gradual curvature that limits diffraction at the edges, ensuring a stable response on and off axis. The overall aim is to achieve neutral reproduction without digital processing, in order to remain as close as possible to the source.
Topping Professional MA4: Resonance control
The MA4s employ an internal damping chamber combined with absorbent materials to attenuate resonances around 1kHz. This architecture improves midrange clarity and reduces potential colouration in the final sound reproduction. The rigid, compact cabinet maintains a balance between mechanical damping and bass extension.
Topping Professional MA4: Flexible usage context
The sound diffusion of the MA4 is designed to remain consistent in different listening environments, from studios to untreated workspaces. Controlled directivity limits the influence of early reflections on sound reproduction and maintains a balanced response at different listening distances (from 0.3 to 2.5m). The front bass reflex port allows for placement close to walls without altering the low-frequency response.
Topping MA4 Professional: 50W+25W amplification
For its amplification stage, the MA4 benefits from Class D bi-amplification, which separately powers the low-midrange driver and the dome tweeter. Harmonic distortion remains low across the entire frequency range, ensuring accurate reproduction even at high sound pressure levels. The system delivers 75W (50+25W) of continuous power, with a frequency response of 49Hz to 20kHz and a maximum peak level of 105dB at 1m.
