SPL Crossover MKII

The SPL Crossover Mk2 is the next evolution in high-end analog crossover design—crafted for audiophiles and professional fidelity systems that demand nothing less than perfection. With extended crossover frequency options, precision tuning capabilities, and proprietary VOLTAiR technology, the Crossover Mk2 brings stunning analog purity and dynamic range to any stereo setup. Available in black, red, or silver, it’s as visually striking as it is sonically powerful.

Key Features

• 18 Selectable Crossover Frequencies: Individually adjustable low and high pass settings from 20 Hz to 3.6 kHz.
• 12 dB/24 dB Slope Control: Precisely shape your crossover curves.
• Phase Alignment Control: Full 360° variable phase adjustment for perfect integration of subwoofers and top speakers.
• Stereo/Mono LP Output Options: Seamlessly integrate one or two subs with stereo or summed mono output.
• Switchable High-Pass Filter: Run main speakers full range or filter as needed.
• Level Control for Bass Output: Fine-tune sub levels from -10 dB to +10 dB.
• Balanced and Unbalanced I/O: XLR and gold-plated RCA connectors ensure universal compatibility.
• VOLTAiR 120V Technology: Industry-leading dynamics, headroom, and sonic clarity.
• Low-Cut Filter: Removes sub-20 Hz rumble for cleaner output and reduced amp strain.
• AMP CTL Function: Trigger on/off multiple external devices with a single switch.

Unrivaled Audio Performance

Unlike most systems that rely on digital crossovers, the Crossover Mk2 stays 100% analog, preserving sonic integrity across the full spectrum. Whether you're integrating a subwoofer or splitting mid-high drivers, the Crossover Mk2 delivers ultra-low THD+N (<0.001%) and a stunning dynamic range of up to 138 dB, thanks to SPL’s proprietary 120V VOLTAiR technology.

Tailored Crossover Precision

With 3 selectable frequency bands and 6 stepped options per band, users get a total of 18 crossover points:

• High Band (1.5 – 3.6 kHz): 1.5k, 1.8k, 2.1k, 2.6k, 3k, 3.6k

• Mid Band (300 – 720 Hz): 300, 360, 420, 510, 600, 720

• Low Band (50 – 120 Hz): 50, 60, 70, 85, 100, 120

These settings allow audiophiles and engineers to perfectly tailor their systems with precise crossover control.

Smart Controls for Seamless System Integration

• ROLL-OFF: Select between 12 dB or 24 dB filter slopes for the crossover.

• LOW CUT: Filters unwanted sub-20Hz content from both high and low paths to preserve clarity and system health.

• PHASE SWITCH: Offers ±180° adjustment range for exact timing alignment between subs and mains.

• BASS LEVEL KNOB: Add warmth to thin recordings or correct sub/satellite mismatches.

Connectivity & Control

Whether your setup is home hi-fi or professional mastering, the Crossover Mk2 fits effortlessly with both XLR and RCA connections. Its AMP CTL ports even allow you to turn multiple system components on/off simultaneously via trigger control—ideal for paired power amplifiers or processor chains.

Made in Germany – Built to Last

Handcrafted at SPL’s German facility, the Crossover Mk2 uses through-hole technology for premium component selection and longevity. The internal linear power supply with a shielded toroidal transformer ensures rock-solid operation and audiophile-grade performance.
