There are two major
categories of speaker design - bookshelf speakers and floor standing speakers.
Floor standing models generally provide deeper bass, because the floor itself
augmentes the output of the driver. In addition, the increased volume of the speaker
box means more air in the enclosure and, consequently, greater compliance.
Compliance is an expression of the amount of energy required to move the
woofer; in floor standing models, it is quite high and more bass energy is
produced. Floor standing speakers also tend to improve high frequency response,
because they are usually designed with the tweeter at eye level. This localized
tweeter placement, while nothing more than a basic construction technique,
dramatically improves the frequency balance in the high range.
If all these
advantages are inherent in floor standing speakers, why do speaker
manufacturers bother to build bookshelf models? Mostly, for practical reasons -
size, space, price and convenience are the most important consideratiions.
Bookshelf speakers, as the name implies, can be placed on a shelf. They can
also be placed on the floor of course, but for quality reproduction, the added
expense of a speaker stand is normally necessary. Bookshelf spaekers are
usually smaller than the floor standing variety, less expensive, and much
easier to handle. In short, for many listeners, the sonic advantages of floor
standing speakers are not worth the added hassle and inconvenience.
The new technics
SB-T20 speakers offer the best of both worlds. They are floor standing
speakers, but in a sleek, trimmed down package. And their prices are in line
with equivalent bookshelf models. With the additional enclosure volume and
ear-level high frequency drivers, they deliver sound which is on a par with
fine floor standing models. Yet, their futuristic, pillar-like design takes up
less space in your listening room or your dance floor. Plus, they are
lightweight and easily movable. Technics reputation for innovative design can
only be enhanced by our new SB-T20 bass reflex speakers.
