Sapphire Audio Sapphire XLs Care & Cleaning, Port Plugs, Taking care of Piano Gloss finish

∙Stereo subwoofers will usually yield the smoothest bass response when they are placed asymmetrically in the room. A good way to start is with one in or very near a room corner and the other subwoofer about 1/3 of the way along a wall.

∙Experiment with the phase of your subwoofers relative to your Sapphire XLs. Correct phase is dependent on the relative distances of the Sapphire XLs and sub(s) to the listening position. Leave the Sapphire XLs in their normal phase, but use the phase adjustment of the Force, Titan or Maestro to fine tune. Easy, detailed instructions for subwoofer adjustment and setup can be found in the subwoofer owner's manual or on the ACI website.

Remember, it’s what fits your room and sounds the best to you that counts. Position the speakers to give you the sound you want.

Port Plugs:

Normally, the Sapphire XL's rear ports are an important part of the Sapphire XL's sound quality and bass response. In some situations, it may be beneficial to plug these ports with the supplied foam plugs. Plugging the ports will reduce the bass output. Plugging the ports will change the Sapphire XLs into an aperiodic system with a more gradual low-frequency roll off that begins at a higher frequency. We suggest experimentation in the following situations:

1.If using the Sapphire XL with a quality subwoofer such as the Force XL, Titan XL or Maestro XL. Installing the foam plugs may result in a smoother transition between the subwoofer and the Sapphire XL.

2.If you have a room-setup situation in which the bass seems to be too prominent. This might occur if the Sapphire XLs are pushed right up to the walls. It will depend on room dimensions and other equipment used.

Install the foam plugs by inserting so they are fully in the port. They may easily be removed using tweezers, pliers or something similar.

Care & Cleaning

The finish can be easily cleaned by gently rubbing with a recommended MicroFiber Polishing Cloth. These soft, plush, microfiber cloths provide superior cleaning results. They contain no chemicals and are ideal for any fine musical instrument, furniture or speaker system. With the MicroFiber cloth your Saphhire XLs will polish perfectly without the need of chemical cleaners. Sometimes it helps to “fog” the area with your breath like you were cleaning a pair of glasses.

Taking care of Piano Gloss finish:

∙The Piano Gloss finish is essentially an automotive finish and can be cleaned and “repaired” in a similar manner.

∙If there are rub marks, fingerprints, etc. that aren’t coming out with just the cloth, try Meguiar’s Quick Detailer Mist & Wipe. This product can be purchased at just about any place that sells automotive wax and such.

∙If the finish has been dulled by something rubbing against it, or finely scratched it can be repaired using other Meguiar’s products. Meguiar’s Mirror Glaze, Show Car Glaze #7 is a good place to start. It is very gentle. If #7 isn’t aggressive enough, start with the #4 version, then follow-up with #7 (the lower the number the more abrasive it is). After rubbing out by hand you can remove any residue using a clean cloth.
