Why This Is Here

SPL makes monitoring gear for major studios. The Phonitor X's Crossfeed Matrix is the most convincing implementation of crossfeed we're aware of — it makes older hard-panned stereo recordings less fatiguing without sounding processed.

Who It's For

Experienced listeners with a serious headphone collection, particularly reference-tier open-backs with high impedance.

Build & Materials

120V VOLTAiR rail technology, discrete circuitry, balanced XLR inputs and outputs, 4-pin XLR and 6.35mm headphone outputs. Made in Germany.

This is the reference. Speaker crossfeed simulation, individual channel volume control, insane detail and power. Used in mastering studios worldwide. If you're building a dream studio and doing serious work on headphones, this is where you end up. The crossfeed simulation actually makes mixing on headphones less fatiguing and more translatable. Not cheap, but nothing at this level is.
