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.

Altec Lansing Five

The Model Five utilizes a novel technique; It employs three drivers in a two-way system; a single bass driver, but two drivers for high frequencies instead of one. The result is increased midband sensitivity, 91.5 dB SPL at 4 feet, which is quite high for a speaker system i the Five's price range.
And, since the high-frequency energy is evenly divided between two drivers instead of just one, system power capacity is increased over single driver designs. The drivers are positioned on the baffle in a manner that produces uniform dispersion and an accurate stereo image whether the cabinnet is placed vertically or horizontally.

The vented enclosure and 12-inch bass driver combine to produce excellent low-frequency energy response to 45 Hz. Fundamentals are tight and clear, with a minimum of distortion, and without doubling or artificially accentuated upper bass frequencies. The Five eliminates the "boominess" soprevalent in other speaker systems in its price range.

The hand-rubbed, genuine oiled walnut cabinet is tastefully styled with finished baffle and removable knit grille.
