The dogs first swivel 90°, then clamp the lo udsp eak ers frame to the dry- wall as you tighten the screws.
Recommended A mplifier Power For satisfactory performance, we recom- mend an amplifier with a power rating of 10 to 150 watts for the DS8.3; 10 to 175 watts for the DS8.5. Curiously, most speakers are not damaged by large amplifiers but by small amplifiers.

Sometimes, you will need to use the “notching” technique to reach areas your drill bit won’t reach or to turn corners (e.
