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.

Audio Academy Phoebe III are two-way floorstanding loudspeakers with bass-reflex. Following drivers were applied: – tweeter 27 TBC/GTV from SEAS – and Visaton's low-midrage W 170 S, Ø 170 mm. The tweeter consists of an aluminum-magnesium alloy diaphragm and paper cone coated with material eliminating its own resonance. Visaton is equipped with medium size magnet and inexpensive die-cast basket. Below we find a bass-reflex port. At the back there are single, golden plated binding posts but the space between them is too small. That's a flaw of the whole terminal plate – you buy them together. I think that Audio Academy could think of some kind of upgrade kit – they could call it “special addition” or whatever. They could offer aluminum, nicely described plate with WBT's binding posts. They could also add some better internal wiring, better spikes and so on. Another option could be upgraded crossover – with point to point design, better resistors and cross coils. The costs of such upgrade will be significant – most likely not much lower than the price of the speakers but I can assure you it is worth it! Cabinets are made of MDF and strengthened inside with cross-bars. The interior is dumped with thick felt plates, fixed at the sidewalls, on the top, behind low-midrange speaker, and some also at the bottom of the cabinet. The crossover is fitted to printed-circuit board, that is screwed down to a small MDF block. The latter is glued to the back wall behind the bigger driver. There are polypropylene capacitors (e.g. from Philips) and core coils. Internal wiring (to binding posts and to the drivers) is executed with OFC wire. There is a very nice natural veneer outside. Loudspeakers are equipped with black bases – bit bigger in the front than speaker's outline. They stand on brass spikes with round ends. Speakers are offered with grills.
