Two-Way Design: The PSB Alpha Series B1 bookshelf loudspeaker features a true
two-way design that employs a single 5.25" mid-woofer paired with a single .75"
ferrofluid-cooled tweeter. The result is an extremely tight sound
with excellent imaging characteristics
- 0.75" Tweeter w/ WaveGuide: Each Alpha Series B1 loudspeaker is equipped
with a 0.75" aluminum dome, ferrofluid-cooled tweeter for crisp,
clear highs. The B1 bookshelf speaker's tweeters utilize an
acoustical waveguide to deliver, more even high frequency response, no
matter what part of the room you're in.
- 5.25" Woofer: Each PSB Alpha Series B1
speaker employs a 5.25" injection molded metalized polypropylene woofer
with rubber surround for accurate, detailed midbass.
- Crossover Network: The tweeter and woofer are
crossed over at 3,000 Hz.
Bass Reflex Cabinet: The PSB B1 loudspeaker utilizes
a bass reflex enclosure with a rear-firing port for greater efficiency
and bigger bass response. The PSB Alpha Series B1
features a black wood grain vinyl cabinet that matches almost any decor.
The speakers come with removable
aluminum (metal-mesh) black grilles.
5-Way Binding Posts: The 5-way binding posts will
accept bare wire (up to 12-gauge), pin connectors, spade connectors,
and banana plugs (single or dual). The speaker's binding posts are
color-coded (red/black) for easy identification between positive and
Mounting Options: The PSB B1 loudspeakers include eight
self-adhesive rubber feet to safely and securely place the speakers on
floor-stands or other AV furniture. Each PSB Alpha Series B1bookshelf speaker also features a single keyhole slot and dual 1/4"-20 threaded insert to wall-mount
the speaker. Each Alpha Series B1
speaker has a single keyhole slot on the back panel to easily wall-mount
loudspeaker also features
dual 1/4"-20 threaded inserts to wall-mount the speakers using optional articulating brackets (sold separately).
Placement: The positioning of the left and right speaker can
play a major role in their acoustic performance of a pair of loudspeakers. The
position of speakers in relation to the walls, floor, and ceiling of your
listening room will also often affect the way a speaker sounds.
- Positioning: The optimum placement height for bookshelf
speakers should typically be set with the tweeters at about the same height
as your ears when seated. Generally, you will receive the best imaging and
other spatial qualities if the speakers and your listening position form an
equilateral triangle, with the speakers not quite as far apart from each
other as your position from the speakers. If your favorite listening
position is equally distant from both speakers, angling or "toeing" the
speakers inward about 5 to 10° usually produces the best convergence of high
frequencies for that listening position. Different listening positions may
require different angling.
- Room Boundaries: For the greatest bass response and
feel, place the speakers near three adjoining surfaces - in a corner of a
room near the floor or ceiling - where the convergence of the two walls and
floor/ceiling produces an amplifying effect that resembles megaphone-like
sound. Placing a speaker away from all room boundaries will produce the
least amount of bass, however your own listening preferences should decide
what proportion of bass response is ideal for each room setting and space.
Alpha Series: The all-new Alpha Series has been rebuilt with
enhanced custom drivers and a new crossover design that work perfectly together
to deliver natural, detailed sound with precision and less distortion. PSB's
Alpha Series of loudspeakers offer five models (T20
B1 Bookshelf, and
C10 Center) to fit the needs of almost any audio setting. The Alpha Series
of speakers offers audiophile sound quality at an affordable price; but not at
the expense of appeal, style, and sound.
Note: Every PSB Alphas Series speaker is meticulously tuned
and tested at Canada's national research facilities to deliver the most
accurate acoustics under the most demanding of listening conditions.
Optional Powered Sub: Add a PSB SubSeries powered subwoofer
(sold separately - see Accessories Tab) to the Alpha Series loudspeakers for an
even more immersive listening experience with bigger bass response.
