SPL Crossover Mk2

The SPL Crossover Mk2 is a premium, fully analog active crossover engineered to seamlessly integrate subwoofers or bass loudspeakers into high-end audio setups without converting signals to digital. Powered by SPL's proprietary 120V VOLTAiR technology, the Mk2 features expanded frequency control, switchable 12 dB/24 dB roll-off slopes, continuous 360° phase alignment, and versatile gold-plated XLR/RCA connectivity. Available in Black, Red, or Silver, it offers audiophiles ultimate flexibility and uncompromising analog sound quality. Key Features Proprietary VOLTAiR 120V Technology: Operates at a +/-60V DC rail—four times that of standard op-amps—delivering massive dynamic range, high headroom, and rich detail. Pure Analog Signal Path: Avoids digital conversion steps in high-end analog signal chains. Flexible Crossover Frequencies: 18 selectable crossover points per section ranging from 20 Hz to 3.6 kHz across three frequency bands. Selectable Roll-Off Slopes: Switch between 12 dB or 24 dB per octave slopes independently for High Pass and Low Pass filters. Variable 360° Phase Control: Full analog variable phase alignment (0° to 180° and 0° to -180°) to sync subwoofers with main speakers, with a complete bypass (OFF) mode. Integrated Low Cut Filter: 20 Hz sub-harmonic filter relieves amplifiers and speakers of inefficient, inaudible ultra-low frequencies. Universal Connectivity: Gold-plated XLR and RCA stereo inputs and outputs, with output signals available on both formats simultaneously. Mono/Stereo Low Output: Run single or dual active subwoofers with a flip of a switch. 12V Triggering (AMP CTL): Smart power sequencing for up to four downstream amplifiers or components.
