Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.

Features
Woofer: The Boston Acoustics VSi 580 uses an 8"
DCD (Deep Channel Design) copolymer woofer with a die-cast aluminum basket. The
DCD woofer uses a deeply grooved pole plate that enables the voice coil to
travel farther for greater output without bottoming.
Tweeter: The VSi 580 uses Boston's 1" VR aluminum dome
tweeter. Compared to a soft dome, aluminum is equally light, yet more rigid.
Compared to other hard dome materials, aluminum is better able to accurately
track the input signal. There is a unique pivoting tweeter cup offering
placement flexibility; the aluminum tweeter cup
also acts as a heat sink.
Moisture Resistant: The VSi 580 is well suited for humid
environments like the kitchen or bathroom. Make sure they are positioned so
that moisture cannot collect inside them. They are not designed for locations
where they will be submerged.
Boundary Compensation: The boundary compensation circuit shapes
the sound to counteract the effect of placement too close to an adjacent wall (or
ceiling, floor, or corner). The switch should be turned on if the speaker is mounted
closer than 18 inches from the junction of two surfaces or closer than 24 inches
from a corner.
Inputs: Spring loaded posts will accept banana plugs (single
or dual) or bare wire up to 12 gauge.
Mounting
Placement: Because you can control the direction of the high
frequencies with the pivoting tweeter, you can mount these in-ceiling speakers almost
anywhere. For optimum results, place the speakers 8 to 12 feet apart so they form
a triangle with the listening area.
Installation: After a 10-7/8" diameter cutout is made
the speaker is installed into the opening and held into place with four integral
plastic mounting ears. The required depth to install the speaker is 5" from
the mounting surface (this includes the thickness of the drywall). Behind the
opening there must be a 1" clearance around the speaker to accommodate the
ears. The mounting wall material must be at least 1/4" thick for the mounting
ears to work.
Magnetic Grille: The grille is magnetically mounted for easy
installation.
Paintable: Both the frame and grille can be painted to match
the ceiling. A plastic paint mask is included to protect the speaker from being
painted as well.
Optional Bracket: The NCBR8 new-construction bracket (sold
separately) can be used to simplify installation in new construction.
