Yamaha's compact NS-AW150 bookshelf speakers provide an affordable way
to enjoy your music or television programming on a deck or under a
porch. You can bring them in during the cold months and set them up
indoors, too: their high build quality and good sound lend them equally
well to two-channel indoor listening.
The speakers, which are sold as
a pair, each use a 6.5-inch high-compliance, polypropylene, mica-filled
woofer and .5-inch PEI dome tweeter. The drivers are optimized for high
rigidity but low mass, giving them reasonably high sensitivity (80 dB
with 2.83V at 1 meter), another way of saying modest amplifiers won't
have much trouble driving them. Their acoustic-suspension cabinets are
sealed to prevent undue resonance or tubby, tuneless bass, which often
results from low-cost ported designs.
With a nominal impedance of
6 ohms, the speakers will work nicely with amplifiers up to 35 watts
per channel, nominal, or 120 watts, peak power. They boast a frequency
response of 80 to 40,000 Hz (+/-3 dB), giving you decent bass output for
their compact size and unusually extended high-frequency response for
your most demanding digital media. For indoor use, you may want to
augment their performance with a subwoofer to deliver deeper and more
powerful bass; be sure to select one with a variable crossover so you
can tailor its upper frequency to effectively "take over" at the point
of the NS-AW150s' lowest deliverable frequency.
The speakers are
magnetically shielded, so you can place them on or near a TV or video
monitor without fear of picture degradation from their magnetic fields.
Five-way binding posts simplify connection with several different
terminations of speaker cable (including banana plugs), and the
NS-AW150s even come with two lengths of cable to get you started.
While you wouldn't want to leave the speakers exposed on, say, the deck
of a boat, they are water resistant and designed to withstand light
wind and rain--a benefit of their sealed enclosures and rugged metal
grilles. The speakers come with mounting bases and brackets.
