Cyrus CLS50 Loudspeaker
The key technologies of Cyrus CLS 50 explained-
H.F. Driver
The 1” silk dome tweeter achieves high linearity and low hysteresis due to an unusually large
surround. The surround acts as a second radiating element in addition to the dome. Careful
optimisation of the moving structure and its faceplate loading has allowed exceptional control
of the drivers directional characteristics. The result is excellent integration between the two
drivers. Low viscosity ferro-fluid is used to increase the power handling while preserving
micro detailing and stereo focus.
Bass-Mid driver
The 5” bass unit incorporates a number of technologies combining to provide extremely high
performance for the size of the driver. A specially shaped termination to the cone controls
resonance allowing natural voicing even under high power. The vented magnet and coil
former reduces compression and improves resolution. An advanced polymer chassis material
stops “ringing” in the basket of the driver.
Dual Gas-flowed Port
The dual gas-flowed reflex port is borrowed from the CLS70 and enables us to allow this
compact box to provide stronger and more controlled bass than would normally be prudent
for the size of the cabinet.
High specification components, the hidden benefit
Cyrus specifies unusually close tolerances (5%) for all of our drive units and crossover
components. We also test every pair of HF drivers for matching Left/Right before assembly.
This means that unlike most speaker manufacturers we produce fully matched loudspeakers.
It is this attention to detail that ensures consistency and provides confidence to the consumer
that what they purchase performs as the design team intended and not a mass-produced
approximation of the original idea.
