Definitive Technology SM55 Flawless!! MARKED DOWN!! [Expired]

no longer for sale

PRICE DROP!! I purchased these speakers about 4 months ago to use in a very quiet listening situation. Because of apartment life, I've decided to move over to a headphone setup. These speakers were removed from the boxes, placed on stands and never touched. They were powered by a very high quality integrated amplifier in a smoke free, pet free, child free home. The grilles have never been used or removed from the box. These speakers probably never played over 70-80db. They have amazing detail and sonic presence at low levels. I loved their articulate sound quality and full range response on all types of music. Apparently, my new neighbors didn't appreciate their full range response :-) (Please note: speaker stands are NOT included).

For those not already familiar with these fine speakers, here's a little more info from the website:

  • Second generation patented 6-1/2" BDSS mid/bass driver with Linear Response Waveguide technology for flat, accurate response with micro-detail retrieval and three-dimensional imaging
  • Cast aluminum driver baskets
  • Second generation pure aluminum dome tweeter for smooth, extended highs
  • Top-mounted racetrack bass radiator for outstanding bass response
  • Non-resonant braced enclosure ensures pure, uncolored performance
  • High-gloss anti-diffraction baffle and shaped enclosures reduce diffraction for open and spacious imaging
  • Crossover network features oversize inductors and premium Mylar capacitors for audiophile-grade sound quality
  • Integrated Zobel network makes the SM55 easy for amplifiers to drive
  • Bi-amp/bi-wire all-metal 5-way binding posts

Redesigned From the Ground Up for Superior Performance, Utility and Beauty
The new Definitive StudioMonitor series is the culmination of over 20 years of research and development to create monitor-quality shelf speakers with the perfect balance of high style, utility and most of all performance.

The Most Advanced Technologies for the Most Advanced Performance
If you love great sound you must experience Definitive's StudioMonitor 55. Its combination of racetrack bass radiator technology, and our latest generation patented Balanced Double Surround System (BDSS) bass/midrange drivers, all housed in a rock-solid attractive enclosure, delivers unsurpassed sonic performance.

Each SM 55 features a cast-basket 6-1/2" (17cm) second generation BDSS midrange driver and a 1" (25mm)

The SM55 features a second-generation patented BDSS bass/midrange driver for best-in-class sonic performance

pure aluminum dome tweeter. The driver features Definitive's patented Balanced Double Surround System (BDSS) technology that supports the speaker cone at both the inner and outer edges allowing longer, more linear excursion for greater clarity and finely textured inner detail. A new patent pending Linear Response Waveguide™ smoothes off-axis frequency response and disperses sound over a wider area for crystal clear intelligibility for every listener in the room. The tweeter is a pure aluminum dome, which has been heat-treated to relax the crystal structure and then coated with a ceramic to produce extended highs that reveal nuance and shimmer without a trace of edginess.

The BDSS long-throw bass/midrange driver is pressure coupled to a top mounted racetrack bass radiator to extend and amplify bass frequencies. The total bass radiating area of a SM55 is substantially greater than that of a single 10-inch woofer but with far greater control, definition and speed than a single sluggish large woofer. The StudioMonitor's bass performance is nothing short of astonishing in its depth, detail and musicality.
