Product Information
Shipping & Returns

The Amphion One18X is a reimagined classic — taking the revered accuracy and transparency of the original One18 and extending its performance where it counts.

Still ultra-compact and effortlessly revealing, the One18X now digs deeper in the low end, reaching down to 38Hz. That means tighter control over sub-heavy sources, fuller kick and bass response, and more confidence when mixing bottom-end detail — all without needing a subwoofer. Combine that with an SPL increase of over 6dB, and you get greater headroom, cleaner transient response, and improved dynamic range across the board.

Its design remains true to Amphion’s uncompromising passive philosophy: a single 6.5” aluminium woofer and a 1” titanium tweeter, coupled with a passive radiator in a sealed cabinet. Every component has been finely tuned to deliver best-in-class phase coherence, midrange clarity, and imaging, making it easy to trust what you`re hearing — even at low volumes.

Optimised for use with Amphion’s Amp700 or Amp400.12, the One18X is perfect for small-to-mid-sized control rooms where space is tight but expectations are high. Whether you`re producing, mixing, or mastering, the One18X gives you the depth, honesty, and musicality you need to get it right — fast.
