SPL Audio Crossover

Active analog 2-way crossover – The Crossover is one of a kind. – It is analog! No DSPs, no AD/DA conversion. – It is active! It fits to all kinds of speakers.

You can tune crossover frequencies and phase response all in the analog domain in real time with real switches and controls. And –of course– with SPL’s unique VOLTAiR technology. That means headroom, dynamic range and real sound in abundance.

When you add a subwoofers to your top/main speakers the crossover is most often digital. That is been sold as a plus – but it isn’t. Because digital signal processing involves AD-conversion, DSP processing and DA-conversion. The audio signal undergoes significant treatments and at least the extra AD/DA conversion does not amuse audiophiles.

But now, here is the solution: the SPL Crossover. Fully analog, 120V-VOLTAiR technology, user friendly and amazing sounding.
