Overview: The Boston Acoustics
P450 is sold as a single speaker, this allows you to use one as a center speaker, two as a pair of main or surround speakers,
or a package of 3, 5, 6, or 7 in a multi-channel home theater
system. The P450 is voice-matched to the other Boston Acoustics P4 series
speakers. The P450 is sized to fit well along side TVs in the 50 inch range.
Enclosure: The cabinet is extruded aluminum resulting in a
superb structural integrity that eliminates the spurious resonances and
vibration that degrade the sound of typical speakers.
Grilles: The package includes 2
aluminum grilles, one silver and one black, to match a variety of decors.
Tweeter: The P450 speaker uses
Boston's 1" VRH.O. aluminum dome tweeter with AMD (Amplitude Modification
Device). This high output tweeter uses a specially anodized aluminum dome. Compared to a soft dome, aluminum is equally light, yet more
rigid. Compared to other hard dome materials, an aluminum dome is unrivaled in
its ability to accurately track the input signal, in other words, when the voice
coil says "jump," the aluminum dome does so, without changing shape. AMD is used
to further optimize the aluminum dome's output, without taking anything away.
AMD is a patented acoustical tuning device that uses precisely sized hollow
tubes positioned in front of the tweeter to refocus short wavelength energy and
create an extremely smooth, flat response. This is done without using elaborate
electronic components that can degrade the sound's purity.
Midrange/Woofers: The P450
has a 4 1/2" midrange and two 4 1/2" woofers. The mid has a large 1 1/2" voice coil for superb driver control
and extremely high power handling. The benefit of multiple 4
1/2" woofers is authoritative bass response, low distortion, and smooth
uniform upper bass/lower midrange frequency response. Each woofer and the
midrange is built from the ground up for the P4 series speakers and uses a rubber surround for
Video Shielded: This speaker includes MagnaGuard, Boston Acoustics' proprietary magnetic shielding technology. By reducing and containing
the magnetic field naturally generated by a loudspeaker's magnet, MagnaGuard allows you to place the
speaker near a TV or monitor without distorting the picture.
5-way Binding Posts: The
wire terminals are 5-way binding posts, allowing you to connect the speaker wire using
dual banana plugs, single banana plugs, spade connectors, pin connectors, or
bare wire. Bare wire up to 10 gauge fits through the posts. Because of the way
the speaker terminal is recessed into the cabinet, if spade connectors are used,
they need to be angled.
Wall Mounting Brackets: The
P450 is equipped with a metal wall-mounting bracket which can be positioned vertically
or horizontally. Using the wall bracket adds about an inch to the depth of the
speaker. The bracket has three mounting options to allow varied angles. When
mounted vertically, the speaker can face perpendicular to the wall or it can be
angled 15° left or right. When mounted
horizontally the speaker can face
perpendicular to the wall or it can be angled 15°
up or down. Mounting hardware is included.
Bass Management: When setting
bass management parameters on your home theater receiver, the outputs for this
speaker should be
set to Small.
Optional Stands: The P450
speaker can be placed on one of two optional stands, the table top stand (item
number 065P4TS) or the floor stand (item number 065P4FL).
Depth: The measured depth of
the P450 is 3.936". The included bracket is necessary for wall mounting so the
effective depth becomes 4.833".
