Active-Passive Monitor

SE AP-1

Active-Passive Nearfield and Midfield Monitor | 

Compact yet expansive, the SE AP-1 employs the same 1” compression driver used in the SE MF-4, coupled with dual 5-inch woofers, to deliver seamless coherence, full-range extension, and a soundstage that exceeds its size. Engineered for high accuracy, it achieves ±1 dB linearity and < 0.5% harmonic distortion above 200 Hz at 94 dB SPL, preserving detail and definition even at elevated playback levels. With a precisely controlled 80° × 80° dispersion, the SE AP-1 maintains stable tonal balance and spatial integrity across the listening area, producing a focused, three-dimensional image from a compact 40 cm enclosure.

The SE AP-1 is built around a two-way architecture that prioritizes coherent source behavior, stable dispersion, and low-loss integration between drivers and amplification. Its acoustic geometry and crossover execution are designed so the system holds together spatially and tonally across the listening area, while the dedicated internal analog amplification preserves control, low noise, and transient precision. The result is compact monitoring that remains composed, focused, and predictable in real rooms, even where placement and boundary conditions are less than ideal.
