Maestro Raves...

  • "We have had a lot of excellent designs through our listening rooms. The Maestro, however, was immediately a step above anything we have ever had. The first disc was Steely Dan, and the Maestro did more than just deliver good bass. It grabbed everything coming from the disc, and delivered performance I did not think was attainable for under $5,000, let alone $2100."
    Craig Chase reviewing the Maestro. Read the whole review 

  • The Maestro is handcrafted in the U.S. utilizing the highest quality custom U.S. made driver and separate amplifier.

  • All design and quality aspects combine to yield absolute state-of-the-art sonics. 

  • The Maestro is a large sub, but more compact than you might think given the high output capability. 

  • Like all ACI products, the Maestro is designed to complement your furnishings while being a welcome addition to your listening room. Really no larger than a luxurious end table, the Maestro will look right at home inside your home!

  • The use of the finest lacquers and hardwoods results in a cabinet of exceptional beauty and durability.

  • The cabinet is built to be extremely inert with extensive internal bracing.

  • Acoustical output equal to nearly four Titans!

  • Crossover guarantees a seamless match with any speaker system. If you thought you'd never find a subwoofer that would integrate perfectly with your Maggies or Quads, think again! The Maestro will provide the bass foundation you want, while doing nothing to detract from the sound you now have.

  • Current sensing feedback loop to reduce distortion.

  • Protection circuitry senses & limits excessive input levels.

  • Bulletproof design for high output levels without worry.

  • Designed to be left on, and draws less than 10 watts at idle.
