NEW! High performance shelf/stand monitor loudspeaker
$199.00 each
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 45. Its combination of advanced technologies such as our patented Balanced Double Surround System (BDSS) bass/midrange driver, phase-coherent crossover network and rock-solid enclosure deliver a best-in-class sonic performance.

Each SM 45 features a 5-1/4" (13cm) second generation BDSS midrange driver and a 1" (25mm) 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.
Phase-Coherent Crossover Networks
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 SM45 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 SM45 (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.
Slim Elegant Styling - Rock Solid Performance
All the driver and crossover technology in the world would be wasted if housed in a resonance-prone box. We devoted as much Design and Engineering attention to the styling and construction of the StudioMonitor 45's enclosure as any other part of its design.
The specially contoured high gloss baffle around the drivers and the tapered enclosure sides enhance sound quality by minimizing diffraction distortion. The 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. And that's just we did in engineering the SM enclosures. Internal MDF cross braces further stiffen the system. Tap on the side panel of a StudioMonitor 45 enclosure to hear the solid "thud" of a solid, well-damped cabinet instead of the hollow ring of a poorly constructed speaker.
The Proof is in the Listening
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 45 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.
Now that you're thoroughly impressed with the technology and passion we've poured into the StudioMonitor 45 it is time to find a stocking dealer near you to audition this remarkable achievement of art and science.

[The StudioMonitor 45s] "reveal intoxicating levels of detail and texture. [They] 'disappeared' in my room as has no other speaker, allowing music to simply bloom throughout my room, to surround and surprise me.

Had these speakers for about two weeks now with the 800s in the back, pro center 2000 and supercube 2k, they sound awesome! Using them for both movie watching and playing music, both have excellent quality! I have no complaints about these speakers other than that I could not find them for sale on black Friday haha
