D1.1 Bookshelf Loudspeakers

The Raidho Acoustics D-1.1 is a compact 2-way stand mount loudspeaker. It features the Raidho Diamond Driver and the Raidho Ribbon Tweeter. Through their work with the Raidho Diamond Drivers, Raidho learned something essential about audio reproduction: Less is truly more. According to Raidho, when the resonances, which are always present in a system, are minimized and almost removed, and when your psychoacoustic capabilities no longer have to deal with unwanted resonances, then your mind is free to enjoy the reproduced music to a whole new level making the performance of the D-1 seemingly endless in all respects.

Available in Black piano All possible paint colors Walnut burl veneer finish.

    The Raidho Acoustics C-2.1 is a 2.5-way floorstanding loudspeaker. It is built with the same unique qualities as the C-1.1, but with a somewhat larger cabinet and an additional Raidho Ceramix Driver. This relieves the workload on the upper Ceramix Driver, which results in a deeper bass and an even higher dynamic headroom. The extended bass frequency and the larger dynamic contrasts give the music performance more substance and a very natural tone color.

    The Raidho Acoustics C-3.1 is a true 3-way speaker design. It is built with a dedicated Raidho Ceramix mid-range driver and three Raidho Ceramix woofers, which are paired up with the Raidho Ribbon Tweeter. The greatest advantage of the 3-way design is that the narrower pass-band of the drivers makes it possible to optimize and tailor them closer to the desired sonic capabilities. The optimization of the drivers makes the moving mass of our mid-range smaller, the membrane lighter and stiffer, and makes it possible to fit the mid-range with a lighter and an even softer spider and surround. The results are more resolution and better transient handling in the music performance where the mid-range meets the tweeter.

    The C-3.1 is designed for mid-sized rooms, and it will let you get the very best out of your music collection.

    The Raidho Acoustics X-3 is 2.5-way Raidho loudspeaker design. The X-3 is equipped with four dedicated 4-inch ceramic, ceramic mid-bass drivers and one 8-inch side-mounted bass driver. Central is the Raidho Acoustics’ one-of-a-kind sealed-ribbon tweeter that employs an array of neodymium magnets to create an extremely powerful force field, in which an ultra-thin membrane is suspended. The weight of the membrane in the Raidho ribbon tweeter is less than 0.02 grams. Due to the low membrane mass, the tweeter stores no energy and has no resonances. This special tweeter design does not leave any ‘sonic fingerprint’, which makes its performance extraordinary. The central pair of the four mid-bass units extend from the deepest bass to the midrange crossover at 3 kHz. The outer pair of the mid-bass units gradually relieve the inner pair starting at 250 Hz and extend to the deepest bass, thereby reducing the dynamic doubler distortion and increasing the speakers dynamic handling capability. The X-3 side-mounted 8-inch bass driver solidifies performance in the lowest frequencies.

  • XT-1 Mini Monitor

    Raidho and X-1T is an elegant and compact size stand-mount mini monitors. The speaker is built with the Raidho Ribbon Tweeter and a bass/mid-range driver with ceramic membrane and ceramic/titanium membranes. The mid-range drivers feature our newly developed neodymium based magnet system in a long throw and low compression design. The loudspeakers are primarily designed for smaller rooms and can be placed relatively close to the rear wall. The XT-1 is also ideal for studio work and near-field monitoring.

    WHAT IS THE “T” ALL ABOUT? - Raidho has "put the T in the X"

    The Raidho X and X-T series of loudspeakers are all built around the same Raidho X-driver that has a very compact and magnetically rigid neodymium magnet motor system. The X and X-T drivers share an extremely rigid ceramic cone manufactured in a Pio plasma process, requiring over 80 hours to complete, where a ceramic composition layer is formed in liquid through a high current/voltage process.

    The resulting membrane is a sandwich where two extremely stiff ceramic skin layers encapsulate a much softer aluminum core. This sandwich construction has two great benefits for audio reproduction:
    1. The cone is very stiff, and
    2. It has very very good damping properties

    The X driver is truly state of the art in this respect, where the cone works pistonic up to more than 10 KHz and where the first order resonance is a peak of less than 6dB, creating a driver with a membrane that is extremely “quiet” in its working range from the deepest bass, until rolls off at approximately 3Khz.

    The X-T driver is a further refinement of this already incredible "X-" driver further improving on performance. The T stands for Titanium. In a vacuum aided process, Raidho adds layers of titanium nitride and pure titianium on top of the ceramic X driver membrane, transforming the X ceramic sandwich cone into an even stiffer and better damped 7 layer sandwiched cone. Now a first fundamental resonance of 15 KHz and a breakup resonance of only 3 dB. Achieved is a larger broadband transmission control of the resonances on the cone providing a much more full bodied sound.

    Is it significant? According to Raidho - yes, as revealed to the listener. Clarity and blackness of the background are greatly enhanced to a degree that will leave you amazed over the richness of instruments and natural details emerging from the recording. As realism grows, you will want to further explore the intent and finesse of your favourite artists.
