IMPORTANT NOTICE
All new speakers require a minimum of 60 hours break-in-time before they begin to sound the way they are supposed to. A speaker's performance improves significantly once broken in. It is critical that you have at least 60 hours on your speakers before you evaluate them. Don't worry if your speakers do not sound perfect the first time you play them. This is normal until they are broken in. If you are having difficulty getting enough hours on your speakers and your 30 day return privilege is getting near, call us. We will work with you. Please give us the courtesy of breaking the speakers in before you determine they don't sound right.
Many of our customers break their speakers in by:
3
A) Leaving them on at moderate listening levels when they are not home. B) Leaving them on at moderate listening levels while they sleep. C) Running pink noise through them.
These methods are not convenient for everyone and we understand this. But please know that you are not giving yourself, your speakers or us a fair chance if you do not break them in before critical evaluation.
THANK YOU!
The Maestro is very heavy. We strongly recommend having two
people available to remove from packaging.
The Maestro Powered Subwoofer
Thank you for your order and congratulations on becoming the owner of an ACI speaker system. The Maestro powered subwoofer(s) will provide you with many years of listening pleasure!
ACI’s Maestro is an extremely powerful subwoofer. Although relatively large, a conventional subwoofer of equal performance would have to be twice the size! The Maestro is based on the subwoofer technology of our legendary Titan series. An extreme excursion 15" driver is powered by our proprietary amplification using special circuitry to essentially cut the required box volume in half.
Many subwoofers do a respectable job with explosions, shotguns, and crashes. The market is loaded with black boxes and tubes that beg to be "hidden". The Maestro is different . Reasonably sized and attractively built to compliment your fine furniture. A number of fine wood finish choices are available. The Maestro goes way loud, and it goes way deep. Warning: ACI is not responsible for any tickets you may receive for noise violations or domestic disturbance! More importantly, it will allow a seamless and completely transparent blend with your main speakers. Your sound stage will be enhanced, not degraded. Instruments like acoustic and electric bass, piano, and percussion will come through with vivid realism. The Titan and Force have earned a reputation of being some of the most musical subs available at any price. The Maestro continues this tradition of musical excellence in an extreme output configuration.
The internal enclosure is constructed of 1” non-resonant high-density fiberboard with extens ive internal bracing. The mounting for the down-firing woofer is 2" thick for additional resonance control and stability. Solid hardwood panels coated with multiple layers of clear or black lacquer grace the exterior and add additional damping.

Many subwoofers add unacceptable colorations and actually degrade the performance of otherwise fine speakers. The Maestro is adaptable for use with virtually any satellite, electrostatic or ribbon speaker. If you are satisfied with your present speakers but just want more bass power and extension, the Maestro(s) may be the perfect answer. If you own speakers from manufacturers such as B&W, KEF, Apogee, Quad, Thiel, Magnaplaner, Spica, Celestion, Acoustat, Acoustic Energy, Martin Logan, Wilson, etc., you’ll find your listening pleasure greatly enhanced with the Maestro subwoofers.
