Both the tweeter and midrange speakers have adjustment controls to tailor the sound to the listening environment. About BIC Speakers Different brands of in-wall speakers may look the same externally, but they sure don't sound the same. We have tested many different brands and we have found these to be the best in the price range. These speakers from BIC America sound phenomenal and are very reasonably priced. They have a good clean sound with tremendous bass response.
Installation is simple.
Insert the rectangular rear bracket into the hole at an angle. Straighten speaker and tighten screws. The metal rear bracket clamps the speaker tightly to the drywall to produce a very rigid acoustically sound fitting. Rough-in kits are for use with new construction, and replace the rear metal bracket with a frame that is mounted to studs. All BIC speakers have overload protection and come with a comprehensive installation guide.
