Product information

Inspired by the classic British ceramic speakers of the ’60s and ’70s, the Royal builds on tradition with a few smart, modern twists.

A more powerful and efficient voice coil and magnet give it a wider sweet spot across the volume range, whether you're playing clean or pushing into breakup.

With a large ceramic magnet, ribbed cone, proprietary cone treatment, and cork gasket, the Royal delivers clear, chimey highs, deep, articulate lows, and that unmistakable British upper-mid growl.

It’s bold, responsive, and full of character, and when you dig in, the smooth transition from clean to creamy overdrive is pure magic.

Voiced to be efficient and forward without feeling stiff, the Royal has just enough compression to keep things musical. If you're after a versatile British-style speaker that can cover a ton of ground and still feel inspiring under your fingers, this one’s a winner.

Handmade in the USA.
