In a stereo
system, the loudspeakers are the key components. Because they are devices that
you hear, the system can never be better than they are, if your speakers are
less than excellent, accuracy will suffer, and so can your enjoyment.
The Boston
Acoustic A70 is a highly accurate reproducer of music. In addition to
faithfully recreating the full audible range of music, the A70 can image more
accurately than most speakers offered at any price.
An accurate
stereo image increases realism.
When you
listen to a stereo system, close your eyes, and find out whether your mind's
eye can "see" where each instrument is located.
Boston
Acoustic speakers are well-known for their ability to recreate an accurate
stereo image that increases realism and enjoyment. The slim profile of the A70
not only makes it easier for you to place the speaker unobtrusively in a room;
more important from a music lover's point of view, the dimensions of the
cabinet minimize unwanted sounds that would ordinarily muddy the stereo
picture. The result is a crisp focused image.
Another
characteristic that contributes to good imaging is a tweeter that's matched to
the woofer in terms of its radiation pattern. A limitation of ordinary tweetere
is that they radiate sound forward in a tight pattern, like a flash-light
radiates light. In contrast, all woofers radiate over a broad area,like a table
lamp. The tweeter incorporated in the A70 radiates in a very broad pattern,
making the woofer and tweeter a well-matched team. Hence, the stereo image is
clear and distinct.
The best
combination of range and accuracy inn its price class.
The A70
maintaining the correct proportion while reaching farther into the bass than
any other speaker in its price class. The quality of the drivers is largely
responsible. The tweeter is the same one we use in most expensive nodel. The
woofer is a helfty 8-inch driver designed to providethe best combinationof deep
bass and efficiency. It reproduces the lowest notes in music - notes that most
listeners never heat, except in live performances.
A room-size
sound from as little as 15 watts
With very
little power, the sound of two A70
speakers will fill an average size room to overfloving. The A70 performs well
with a receiver or amplifier as low as 15 watts per channel. Its efficiency
means you can spend less money on your receiver or amplifier, and get excellent
performance.
