Speaker Break-In   ******Important!!!

Allow at least 60 to 70 hours of playing time before your new ACI speakers will sound their best.

The adhesives and materials used in manufacturing must stretch and flex properly before a speaker will
sound its best. After break-in the bass will be tighter and go lower, imaging and transparency will improve
and the midrange and highs will sound smoother and more natural.

A couple suggestions for quicker break-in:

 

Play the Sapphire  XLs at medium volume while away from home. A CD player on repeat or FM radio

works fine.

 

Place the Sapphire  XLs grill-to-grill and reverse the polarity on ONE of the speakers. Wiring them out-
of-phase like this will cancel much of the sound and allow you to break them in when the sound would
otherwise be obtrusive.

Troubleshooting

Occasionally we get a call or Email from someone who feels there is a problem with his or her ACI

speaker. At least a couple of times a year we will get a call or letter that goes something like this:
“Speakers are not working properly, can’t get enough sound even with the volume turned way up.” The
problem may be different, but with this little information to go on it is almost impossible to trouble shoot the
problem “long distance”.

The following troubleshooting checklist may help:

1)  Are all system hookups properly connected, not partial shorted wires, or reversed connections,

etc?

2)  Did you try the rest of your system with other speakers to determine if the problem exists with

the speakers?

3)  Please be realistic in your expectations. Our speakers offer excellent value but we can’t beat

the laws of physics. For instance, a compact speaker like the Sapphire  XLs will amaze you with
its clean output, but may not play as loudly as a very large speaker.

IF for any reason you aren’t satisfied with the sound you’re getting from your speakers we want to

know about it. Make sure the speakers have had adequate break-in time. Before you call, write or email
please try to narrow down the problem and eliminate other factors. If you contact us we will need to know:

 

The size of your room

 

Where you have the speakers placed

 

What other equipment is in your system

 

Have you tried other speakers (which ones, and did they eliminate the problem)

 

Any other specific symptoms or information you can provide

Our Customers are #1 with us, and we want you to be completely happy with your ACI speakers!
