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.

Lowther Classic 400 loudspeakers


 The Lowther Classic 400 is one of the company's most spectacular achievements in sound propagation. It employs Lowther's well known internal folded horn principle developed here to a mathematically ideal tractrix curve. This is completed by carrying the sound waves between a wall and the sides of the cabinet to finish as a quarter wave. The cabinet is positioned so that the output from the internal horn is directed towards a wall corner or comparable position acceptable to the room acoustics. A second drive unit in an acoustically coupled compartment serves as the forward facing sound radiator. A five-step ambience control enables the Classic 400 to be ideally matched to suit its environment and the preference of the listener.

Two identical drive units are used in the Classic 400. these are the new hand built PM6's having improved magnet and cone systems and special phase stabilising. No electrical cross-over is used between the units. They are acoustically matched by the unique design of the finely styled cabinet. The Classic 400 will be found compatible with practically any good amplifier in the ten to hundred watts output class although sensitivity is so good that as little as two to three watts can be sufficient for domestic listening needs.

 

Abridged description

Type - Corner-reflector and direct radiator

Units - two new matched PM6 drive units in line, facing rearwards and forwards. The latter gives added presence and reinforced bass response. Because no electrical cross-over device is used between the units, there is no loss of power, no distortion and no coloration from such circuitry

Ambience control - A five stage switchable ambience control is fitted to enable the Classic 400 to be acoustically matched to the room it is heard in. This varies the level of output from the front drive unit as desired.

Impedance - Typically 4 to 8 ohms

Power handling - Capacity up to 100 watts

Size (H x D x W) - 810 x 360 x 250 mm (32" x 14-1/4" x 10")

Finish - American black walnut, teak or satin black with clip-on all-over grilles back and front
