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,

should cover almost any application (most drywall is 1/2" thick). The required
depth to install this speaker is 3.195".
New Construction Bracket: For
new construction installations, the NCBTL5 bracket (item # 065NCBTL5) is
Note: There must be 1-1/2"
