The L210 and L310 are the latest descendants of the original ADS mini-speaker which first introduced the concept of big sound from a small box. The L210 and L310 produce superior sound with classic a/d/s/ drivers and advanced crossover technology.
Height Try to place the speakers so they are close to the same height as your ears when you are seated in the preferred listening area. Also be sure the speakers are high enough that the sound they produce will not be constrained by Separation Start at your preferred listening position with the speakers at the points of an equilateral triangle, aimed toward the listening position. (See diagram.
How the brackets should be fastened to the mounting surface depends on the structure and material of the mounting surface. There are two typical situations. One is with the brackets attached to a conventional wall constructed with drywall material over wood studs. The other situation is with the brackets mounted to a wood cabinet or some other solid material. When the speakers are mounted on drywall the plastic screw anchors will be used in conjunction with the screws.
Drive the mounting screws through the bracket, into the holes, until they are firmly set. Connect the wire to the speakers (see wiring tips in following section). Set the speakers in the mounting brackets, placing a rubber washer between the speaker cabinet and the bracket on each side. Secure the cabinet to the brackets with the threaded knobs, placing a second rubber washer around the threaded part of each knob. Position the speaker as desired, and tighten the knobs.
maintenance The drivers require no routine maintenance. Do not let anything touch the drivers. Do not vacuum clean the drivers or front panels of the speakers. Some dust accumulation on the drivers is normal and does not affect the sound in any way. Heavy dirt buildup may be carefully removed with a soft paintbrush if necessary. The enclosures of your a/d/s/ speakers require no maintenance other than dusting. Dust the speakers with a dry or slightly damp cloth.
