Collection: Raidho C Series

C Series This is where it all began. The C Series established both the look and the technological identity of the Raidho brand; from the iconic racetrack rebate of the trademark Raidho ribbon planar tweeter to the Ceramix drivers, with their pale cones that don’t just look different; from the slim elegance of the cabinet proportions to the graceful curvature of the enclosures, so reminiscent of lightweight racing shells and long-ships. It wasn’t just the C Series that was instantly identifiable; once you’d seen the C Series, you’d recognise any Raidho speaker – and that was before you’d even listened to them.

Raidho speakers don’t just look different – they look different because they are different, they’re different for a reason and that difference is performance.

The heart of the C Series lies in the proprietary three-layer Ceramix cones they use. Their sandwich structure, with its rigid skins and inherent self-damping creates incredibly fast yet mechanically well-behaved driver diaphragms. Couple them to the powerful, fully vented and underhung OpenPlan motor architecture and you create a unit sensitive enough to reproduce the tiniest micro-dynamic shift in a signal, quick enough to blend seamlessly with the incredibly low-mass, low colouration Raidho ribbon planar tweeter. These driver technologies represent the foundation on which every subsequent Raidho design has rested – but there’s more to a great loudspeaker than just the drive units. Both the cabinet and crossover are critical to a speaker system’s success – and either one can (and often does) compromise the best drive units.

The C series cabinets are a masterpiece of effective engineering. They combine a precision machined, low-diffraction baffle that guarantees a stable mechanical and acoustic platform, with a thin-wall, low-mass, curved enclosure that provides both rigidity and low-energy storage. By clamping the enclosure between the frontbaffle and the substantial rear spine, we create an inherently stiff and well-damped constrained structure that incorporates the mechanically damped, controlled dispersion ports. Add the light-touch second-order crossover design and you have the hallmarks of the classic Raidho blueprint.

The result of all that care and attention to detail? Incredible presence, dynamics and harmonic resolution – loudspeakers with the natural expressive power, integration and lack of compression to deliver convincing musical performances in real-world environments.

What clients are saying

  • Like Santa Claus...

    Verdant Audio is, by far, the best dealer of audio equipment I have ever dealt with and I am on the West Coast while Verdant is on the East Coast. Scott, the owner, is like the Santa Claus in the movie "Miracle on 34th St.": He makes recommendations about what audio equipment best suits your tastes whether he carries those lines or not. He gives you an opportunity to try products he has in stock. And he works with you, after the sale to make sure your happy even if it means returning a purchase. Who else does all the things?

  • I've had the great pleasure..

    ... of dealing with Scott Bierfeldt at Verdant Audio on a number of recent transactions. I’ve been a serious high-end audio enthusiast for decades and Scott is hands down the best audio dealer with whom I’ve worked. Scott’s audio knowledge is truly impressive. His style is entirely consultive with no sales pressure at all. Working with Scott is like taking audio advice from a good friend that is guiding me to the best choices. In addition, Verdant Audio has an exceptional selection of very fine audio gear. Scott and Verdant are highly recommended.ontent
