Definitive Technology StudioMonitor 45
Precise, potent sound for tight spaces

Definitive Technology's StudioMonitor 45 packs an astonishingly big punch into a surprisingly small package. It should — it's the result of more than 20 years of research and development by Definitive in their quest to create speakers with a perfect balance of style, utility, and performance.

Each rock-solid cabinet features an advanced 5-1/4" mid/bass driver that delivers plenty of impact and detail, plus a 1" pure aluminum dome tweeter for crisp, extended highs that shimmer. If you're a music enthusiast short on living space, these compact gems should be high on your list of speakers to consider.

" In spite of its almost laughably low price, the SM45 is a speaker that demands to be taken seriously…they were unexpectedly full-bodied and offered an astonishing amount of bass reach (down into the upper 30Hz region)—reach few other small monitors can match. …it provides giant helpings of musical richness, relaxation, and enjoyment at a ridiculously modest price. For these reasons and many more, Definitive's SM45s are a no-brainer recommendation for music lovers whose sights are set high, but whose budgets are limited."

— From Chris Martens' review inThe Absolute Sound, April, 2013

Definitive's second-generation patented BDSS driver with Linear Response Waveguide™ technology gives this speaker exceptional sound quality.

High-tech driver design for impressive performance

The StudioMonitor 45s are chock full of technology that's also found in Definitive's top-of-the-line speaker models. Its 5-1/4" mid/bass driver uses their latest Balanced Dual Surround System (BDSS) driver design, which places a surround on both the outerand inneredge of the speaker cone. This helps the cone remain more stable as it moves, resulting in clearer, more accurate sound — even at high volume levels. The '45's mid/bass driver also gets Definitive's second-generation Linear Response Waveguide™. This mushroom-shaped post in the center of the cone smooths off-axis frequency response for broad, even sound dispersion and a more realistic sonic "image." That means every listener in the room gets to hear balanced, open sound with lifelike vocals and instruments.

Crisp, sparkling highs

Definitive also equipped the StudioMonitor 45 with their latest 1" pure aluminum dome tweeter. This advanced driver is first heat-treated to relax the crystal structure of the metal, then coated with a ceramic that helps produce clear, sparkling highs without a trace of edginess. You'll easily hear the subtle high-frequency details in your music, like the sound of wire brushes gently sweeping the snare head, or the bell-like ring of a brass cymbal.

A second-generation pure aluminum dome tweeter yields smooth, extended treble.

It's all in the details

Definitive paid close attention to other important design elements, too — both visible and hidden. At its heart, the StudioMonitor 45 uses a sophisticated crossover network with audiophile-grade components that include over-sized inductor coils and Mylar film capacitors. These give you a smoother, flatter frequency response, more powerful dynamics, and faster transients, for sound with real presence and immediacy. Sturdy, vault-like cabinet construction also plays a big role in this speaker's performance. The '45's well-damped, cross-braced enclosure features a specially contoured front baffle with tapered sides to minimize diffraction and vibrations that can color your sound and reduce accuracy. Plus its rear-firing, double-flared port is specially designed to enhance low-frequency impact, while keeping bass distortion low.
