Definitive Technology StudioMonitor 45 Monitors delivers smooth, extended high frequency with accurate and clear sound.
The Most Advanced Technologies for the Most Advanced Performance
If you love the 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 aluminium 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 theatre reproduction in your home.
