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.

Boston A150 loudspeakers

The new model A150 offers performance similar to our larger, more expensive A200 in a more compact, less expensive enclosure.
The three-way A150 employs a 10-inch acoustic suspension woofer, a 4-1/2" midrange with ferrofluid, and a 1-inch soft dome tweeter with ferrofluid in a 30-1/2" (high) x 16-1/2" (wide) x 8" (deep) cabinet finished in furniture-grade oak veneer.
A 1-1/2-inch black pedestal base is supplied for floor placement.
The tall, slim cabinet together with careful driver placement minimize out of phase reflections from nearby room surfaces (the flor and the wall behind the speaker) for exceptionally smooth response and precise stereo imaging.
