Definitive Technology Studio Monitor 55

Elegant Styling and Rock-Solid Performance

The Studio Monitor 55 is Definitive Technology's must-hear new bookshelf loudspeaker. It combines DT's innovative bass radiator technology with their equally impressive Balanced Double Surround System (BDSS) construction for an incredibly integrative design, and an immensely enjoyable sound. The SM55's cast-basket 6.5" midrange driver and 1" pure aluminum dome tweeter deliver a surprisingly well-rounded frequency response, with sparkling highs, clear, solid bass, and a remarkably smooth and musical midrange. The end result is an extremely detailed, sophisticated sound not often heard in speakers even twice this price. As a music lover, you owe it to yourself to audition a pair.

"The most surprising thing about the SM55s at CEDIA Expo was the way they sounded in that room -- like a speaker two to three times the size and price. The bass was rich and generous...the highs were quite refined, and the midrange was gorgeously smooth-sounding and pure, fitting of a speaker that costs much, much more...in my estimation the SM55 gets the midband better than most speakers, even those priced quite a bit higher."
– Doug Schneider, SoundStage!

The Studio Monitor 55's driver features Definitive Technology'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.

"Bass definition and punch were exceptional, but the 55 isn't just about power, it's a very refined speaker, so classical music and jazz also sounded wonderful."
– Steve Guttenberg, CNet.com

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 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 SM55's bass performance is nothing short of astonishing in its depth, detail and musicality.

The specially contoured high gloss baffle around the drivers and the tapered enclosure sides enhance sound quality by minimizing diffraction distortion. The decorative high gloss grille and cabinet accents add elegance to the matte black tower the way satin piping adds dash to a tuxedo. But the enclosure’s most important job is to be totally inert and resonance free so as not to color the sound. Internal MDF cross braces further stiffen the system. Tap on the side panel of a Studio Monitor 55 enclosure to hear the "thud" of a solid, well-damped cabinet instead of the hollow ring of a poorly constructed speaker.

The crossover network is the real heart of a loudspeaker, as it is responsible for perfectly blending together the sound of the various drivers into a musically seamless whole. The sophisticated design used in the SM55 features premium audiophile-grade components such as oversized inductors, Mylar capacitors for linear phase and frequency response. An integrated Zobel network flattens the impedance of the system so that even budget amplifiers will be able to drive the SM55 loudly without distortion (although a premium amplifier will bring out all the performance this remarkable speaker has to offer). This preserves the phase coherence, transient response and dynamic integrity of the signal for absolutely lifelike music and home theater reproduction in your home.

This extraordinary speaker sets a new reference standard for high-accuracy loudspeakers in its class and achieves equally superb performance with both music and movies. The StudioMonitor 55 reproduces a silky smooth, incredibly detailed sonic image at lifelike volume levels with a sense of ease which is truly remarkable. Movies and music are reproduced with unequaled purity, transparency and lifelike realism.
