Our take on the Boston Acoustics VSi-580T2

by Marshall Chase
Boston Acoustics

Clear sound without the clutter
Boston Acoustics VSi series of in-ceiling speakers provide plenty of sonic presence without standing out in the room. The stereo input of the VSi-580T2 lets you enjoy full, wide sound in any space. Dual pivoting 1" tweeters separate the highs with a powerful 8" woofer covering the lows. Whether you're playing music in a small area, like a home gym or laundry room, or spreading stereo throughout a larger room, this speaker fits the bill beautifully, without getting in the way.

Clean finish, easy set-up
Boston Acoustics VSi is installation friendly, with a paint-ready, low-clearance bezel to make the speaker virtually invisible. Precision designed tweeters can pivot to direct sound right where you want it. There's even a boundary compensation switch to adjust for proximity to room corners.

An in ceiling mounting bracket is recommended for installing this speaker in a new home under construction or in a room that's undergoing major renovation.

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.



Design: With its two tweeters, dual voice coil woofer, and discrete inputs, the VSi 580T2 is essentially two speakers built into one frame. The two inputs can be used to create stereo output where only one speaker is mounted, output left and right surround back channels from only one speaker, or two VSi 580T2s can reproduce both surround and surround back channels. The Diffuse setting creates a dipole speaker, also useful in surround sound applications.

Woofer: The Boston Acoustics VSi 580T2 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.

Tweeters: The two 1" VR aluminum dome tweeters are angled away from one another to create stereo separation. 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.

Stereo Application: The stereo input and dual tweeters deliver a stereo signal from a single speaker design, useful in hallways and other locations where mounting two speakers is not convenient.

Diffuse/Direct Modes: When using the VSi 580T2 as a surround speaker, it can be configured in either direct or diffuse mode. In direct mode, the speaker has an even dispersion pattern in all directions. In diffuse mode the tweeters act as a dipole speaker and create a null field under the speaker perpendicular to the tweeter plane.

Moisture Resistant: The VSi 580T2 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.

Inputs: Spring loaded posts will accept banana plugs (single or dual) or bare wire up to 12 gauge. A jumper plug on the back of the speaker is used to select single or dual input.


Placement: Optimum placement of the VSi 580T2 varies based on how it's used, stereo vs. single channel, diffuse mode vs. direct. If it's the only speaker in a small room, installation in the center of the room is often best. The best placement as a surround speaker depends on how many speakers are used and whether they are surround or surround back speakers, or both simultaneously. The tweeters are mounted on an island that will rotate approximately 180°, so the direction of the tweeter plane can be adjusted after installation. Several specific mounting examples are addressed in the manual.

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 4-15/16" 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.
