Phase-coherent. Time-aligned.
Build from the ground up, or import from REW or rePhase. The math is yours, the work is ours.
Industry standard. Invisible. Pro. Linearized.
Three crossover families plus a phase linearizer, in one builder. Pick the tools that fit your build.
Linkwitz-Riley
Linear-phase crossover ideal for most active systems. Sums perfectly flat at -6 dB crossover points, phase-pure when drivers are polarity-matched.
Invisible
Linear-phase crossover with zero ringing. The Gaussian impulse shape eliminates pre-echo and overshoot, ideal for critical listening where transient clarity matters most.
NTX-Pro
Ideal for pro audio and mastering applications. Linear-phase with razor-sharp rolloff, providing up to 30 dB more driver isolation within the first octave, keeping each driver in its cleanest operating range and unlocking more usable bandwidth.
Phase Linearizer
Creates an all-pass FIR that corrects the phase distortion from your IIR crossover filters. Your frequency response stays true to your tuning, and your system gains the tight transients and focused imaging of true linear phase.
Bring your own FIR.
Already crafted FIR coefficients in rePhase? Drop the export into AirDSP and every tap loads, phase and magnitude intact.
