Real Wood, Real High Performance

Because our speaker cabinets are built in state-of-the-art computer-controlled woodshops, we control the process from drawing to construction, building in the utmost in quality control to own exacting specifications. Complete control gives us the ability to offer real wood and superior performance at reasonable prices -- prices the competition usually charges for... Vinyl. (Given the choice between vinyl and real wood, which would you pick?)

The RTi150 features:

  • Real wood cabinets.
  • Your choice of two real wood finishes: Cherry or Black Oak veneers.
  • Three 6.5" woofers combine the large surface area benefit of a single large woofer (100 sq. inches) with that of small woofers - a high force to mass ratio - for tighter, punchier, more accurate bass response.
  • Polymer-composite Dynamic Balance drivers with butyl rubber surrounds for durability and smooth wide range response.
  • 1" silk/polymer composite dome tweeters for clear, detailed highs.
  • Mylar bypass capacitors in the crossover extend high frquency response and improve detail and transparency.
  • Slim tower design conserves floor space, occupies only about 1 square foot!
  • Anti-diffraction grille and narrow baffle with raised driver bezel to minimize grille diffraction for spacious, 3-dimensional imaging.
  • Floor-coupled Power Port bass venting for clean, low distortion bass you can really feel.
  • Magnetic shielding for safe placement near video sources.
  • Adjustable leveling feet and carpet spikes included to provide stability on any type of flooring.
  • Dual, bi-ampable gold-plated 5-way binding post inputs (with wide holes for large-gauge bare wire connections) for the most secure connections and the most versatile wiring applications.
