Overview: The Boston Acoustics
P430 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 P430 is voice-matched to the other Boston Acoustics P4 series
speakers. The P430 is sized to fit well along side TVs in the 30 inch range.
Enclosure: The cabinet is extruded aluminum resulting in a
superb structural integrity that eliminates the spurious resonances and
vibrations 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 P430 speaker uses
Boston's 1" VR aluminum dome tweeter with AMD (Amplitude Modification
Device). This 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.
Woofer: The P430
has a 4 1/2" woofer and a 4 1/2" passive radiator. The woofer has a
large 1 1/2" voice coil for superb driver control and extremely high power
handling. It's built from the ground up for the P4 series speakers and uses a rubber surround for
durability. In lieu of a ported enclosure, the P430 uses a passive radiator to
augment the bass response by increasing efficiency.
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
P430 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 P430
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 P430 is 3.943". The included bracket is necessary for wall mounting so the
effective depth becomes 4.784".
