What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

Technics SB-RX 50


For superlative digital and audio visual source reproduction the natural choice is Technics coaxial flat loudspeakers. The development speaker combines the even response characteristics of flat diaphragm speakers with the superior stereo imaging of a linear phase system. Furthermore by  placing the high frequency unit coaxial with the bass unit further benefits in terms of stereo imaging are achieved as the whole speaker system now operates as an ideal point source with the added benefits of flat diaphragms. Disturbances in the frequency response of conventional cone speakers due to the effect of the cavity cannot arise with the coaxial flat diaphragm speaker, leaving the crossover in the ideal situation to combine the two drive units.


Coaxial 2-way Flat Diaphragm Speaker System features:
240 mm flat diaphragm bass unit with coaxial 28 mm flat diaphragm tweeter producing an ideal point source for precise stereo imaging.
Bass unit diaphragm constructed of rigid cross carbon material maintaining pistonic motion to above 4 kHz.
Tweeter diaphragm of mica epoxy resin for higher strength and lowest mass, High efficiency samarium cobalt tweeter magnet system
Balancing magnets reduce external magnetic field for AV use so that alonside a TV monitor the SBRX50 will have no adverse effects on the picture.
High purity LC-OFC wiring
Input power 80 W (160 W music)
