Five drawers. Each opens in place, so nothing leaves the page.

The cavity is the waveguide.
Sound does not simply radiate from a cone. XS-Flow engineers the internal cavity as an acoustic waveguide, controlling directivity and standing waves inside a slim enclosure.

Every driver held to ±0.5 dB.
The crossover is the most overlooked part of a speaker. Hand-selected air-core inductors and polypropylene capacitors hold the drivers to ±0.5 dB of each other at the crossover point.

The enclosure is the heatsink.
6061-T6 aerospace aluminium machined to heatsink geometry, so the body conducts heat away from the voice coil rather than trapping it, with every fastener hidden.

A voice coil that stays cool under drive.
A copper-silver composite voice coil dissipates heat faster than copper alone, so the output holds under continuous high-power drive.
