Raidho C1.1 Walnut Burl Stand Mound Speaker. *SOLD*


Good condition. No box.

Product Description

Inside the 25mm high density fibreboard cabinet, the two drive units are affixed directly to the rear face of the 20mm thick aluminium two-piece baffle, giving a very stable mounting for the drivers. The upper transducer is a bespoke, in-house planar-magnetic tweeter with a thin aluminium trace etched onto a diaphragm of mylar sheet. It gives lightning attack transients and low distortion, but is hard to integrate with a conventional moving coil mid/bass unit, not least because the latter is a good deal heavier. With this in mind, the mid/bass unit has a special 115mm ceramic coated coned of just 100-microns thick, with an aluminium base sandwiched between the coating.

These two drive units are divided at 3kHz by a second order crossover using bespoke inductors and capacitors built to high tolerances, set into the narrow (200x370x360mm) but sturdy (12.5kg) cabinet lined with natural sheep’s wool to damp standing waves. This is reflex loaded by a rear-facing port. The finish is – as you’d expect from a high end Danish design – superlative.

The C1.1 just about pulls off the trick of justifying its vast price – and that is no small achievement. Here we have an exceptional small speaker, one that dissolves into the middle distance and letting the music shine through. First things first, and it has excellent bass; that ported cabinet is super-stiff and reins the bass in. It goes down as low as you would expect from a speaker of this size, but doesn’t trip over itself in so doing. It remains taut and tight and tuneful, and there’s no sense of a crude 100Hz bump being engineered in, to give it an apparently weightier sound – it’s even and honest.
