A small
speaker system that produces a clean, undistorted sound image comparable to
much larger, more expensive speakers. In addition, the A60 offers the same
imaging capability, efficiency, and ease of placement as our more expensive
loudspeaker system.
High speaker
efficiency means low amplifier cost.
The Boston
Acoustic A60 is a highly achieve full volume. An amplifier or receiver rated as
low as 10 watts is sufficient (though the speaker can handle as much as 60
watts). This efficiency means you can spend less money on your receiver or
amplifier and get excellent performance.
More
placement options than other speakers, large or small.
Because the
A60 is small and lightweight, it fits easily and unobtrusively into any room.
And because it radiates sound in a broader pattern than most loudspeaker
systems - like a table lamp instead of a spotlight - it performs well in a
veriety of positions, giving you many placement options.
An accurate
stereo image increases realism.
Boston
Acoustic speakers are well-known for their ability to recreate an accurate
stereo image that increases realism and enjoyment. The dimension 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 tweeters
is that they radiate sound forward in a tight pattern, like a flashlight
radiates light. In contrast, all woofers radiate over a broad area, like a table lamp. The tweeter
incorporated in the A60 radiates in a very broad pattern, making the woofer and
tweeter a well-matched team.
The best
combination of range and accuracy in its price class.
It;s not
just how high and how low a speaker can go, but how far it can reach into the
bass and treble regions while maintaining the correct proportion of high and
lows.. The A60 maintains this correct proportion while reaching as high into
the treble and as deep into the bass as any speaker in its class.
The A60's
woofer uses a specially formulated cone material to eliminate frequency
response irregularities at the top end of its operating range. The 1-1/2"
tweeter has unusually wide dispersion for a diaphragm its size, due in large
part to its elastometric edge termination. Its voice coil is bathed in
ferrofluid to improve power handling.
Among the
refinements in the A60 are a single-pole (6 dB/oct) network for uniform
blending of the drivers in the crossover region and a smooth, easy-to-drive
impedance. The grille panel has a 30-degree bevel around its inner perimeter
that virtually eliminates early reflections (diffraction) that can blur the
stereo image.
