...................


Raidho C-Centric was developed as a concept speaker, and it can
be difficult to rank among the other models in the C series. Centric
is simply in a class of its own, original and - yes, eccentric.
The idea originated from the desire to achieve the ultimate 5.1
sound experience in connection with TV and home movies. C-Centric
is design to be symmetrical, and this design makes it possible
to turn the speaker 90° for optimal reproduction
of the sound from the fifth channel - and it works!
Of
course, the design and finish are the same high quality as the
other C models, so visually, Centric fully lives up to the exacting
Raidho standards in every way. Centric comes with a smart, elegant
stand that rounds off and completes the aesthetic entity of the
audiovisual experience.

Raidho
Ceramix Drivers
Raidho
Acoustics has set path to develop the ultimate driver for loudspeakers.
Looking at the driver market today one can see that not much has
changed over the last decade. To Raidho there was little doubt
that the ridged piston cone approach was the only right path to
take in order to make the best possible Raidho dynamic Driver.
No
Driver is better than the magnet motor, yet magnet systems have
hardly changed in the last 50 years or so. To Raidho eodymium
magnets has completely changed the possibilities of making a more
compact and acoustically ventilated (transparent) magnet system.
The Raidho magnet system consists of two rows on neodymium magnets
placed in a push-pull configuration. Apart from creating a very
controllable flux in the magnet gab. The configuration creates
a very open structure, where the rear side of the membrane is
subjected to very little mirror effect from the faceplate of the
magnet structure. One must realize that sound is transmitted from
both sides of the membrane and that a solid thick face plate acts
like a mirror bouncing sound right back at the membrane again.
Measurements on soft membranes like paper and PP indicates that
this mirror signal is only damped by app 8-10 dB compared to the
original signal, by the ceramic membrane the damping is much higher
and appears more in the nature of compression as partial membrane
movements is not possible on a piston type driver. The patented
Raidho magnet system allows air to move more freely and generates
far less compression than any other magnet system on the
market. The sound improvement going from a traditionally built
magnet system to the Raidho magnet system is huge.


Raidho
Ribbon Tweeter FTT75
The
Raidho Ribbon tweeter FTT75-30-8 is a unique sealed ribbon tweeter.
The tweeter employs an array of neodymium magnets to create an
extremely powerful force field where an ultra thin membrane is
suspended. The membrane weighs less than 0.02 g. Due to low mass
the tweeter stores no energy and has no resonances. The performance
is extraordinaire and the tweeter leaves absolutely no fingerprint
on the speaker system
