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 TP1 A (1954)

"Built as a music instrument, sounds like a musical instrument.

This amazing development is yet another Lowther contribution to the art of electro-acoustic reproduction.

The most efficient reproducer of audio frequencies in the world with single driver unit/compound horn housing.

Now in use by Television, Broadcasting and Recording studios throughout the world as a standard monitor."


The PM3 Drive Unit used in the TP1 has been designed specifically for this cabinet and is not not available as a separate reproducer. The cabinet is a "compound horn" design utilizing two horns to cover the entire audible range. The smaller of the two, which has its mouth at the grille at the upper part of the enclosure, is for the middle register and treble range-roughly the frequencies from 150 to 22,000 Hz. These frequencies are distributed through the listening space by a reflector type horn of unique design. The source is near ear level (when seated) as it should be. The range below 150 Hz is derived from the back of the driver unit, through a folded horn whose mouth is located on the uderside of the enclosure. This unusual configuration not only utilizes the space below the cabinet itself as an effective working part of the speaker system, but the remainder of the room as well, since the floor and walls (forming the corner) act as extensions of the horn. Thus, the entire range of frequencies is reproduced by true horns, providing performance of unrivalled purity and smoothness, reproduced free of bass resonant devices, cross-over networks, or units added to compensate for others found wanting. Efficiency of the TP1 is of a very high order, the average input for listening use being about 100-200 milli-watts.

Attractively styled the TP1 is available in a modern distinctive design. Construction is of the finest workmanship, using natural woods throughout. Selected veneers hand rubbed to a lustrus finish assure a beautiful apperance. natural walnut and mahogany are standard finishes available from stock.
