TWO
CHANNELS

SUNDER LABS · MODEL 01

Split the signal.
Own the room.

Two independently driven 54 mm channels, machined apart so nothing bleeds across.

SO SEPARATE,

the crosstalk meter reads zero. We checked it twice, then stopped believing the meter.

PULL IT APART.

Left and right never share a chamber, a driver, or an opinion.

04 · ACOUSTICS

A curve we
didn't smooth.

Raw frequency response, both channels. Sweep the plot. The two lines never diverge more than half a decibel.

05 · SOUNDSTAGE

Drag the source.
Nothing leaks.

Move the emitter anywhere in the stage. The opposite channel stays pinned at the noise floor. That's the −94 dB the whole thing is for.
