Definitive's StudioMonitor 450 is a compact high-performance, magnetically shielded full-range bookshelf speaker. But don’t let its small size fool you—thanks to its 10 inch pressure-coupled Low Bass radiator it belts out the bass depth and punch of a floor-standing loudspeaker. Its non-resonant monocoque cabinets feature Definitive's elegant piano-gloss black lacquer endcap/wraparound grill cloth styling.
The StudioMonitor 450's sonic performance is truly stunning, producing huge razor-sharp, three-dimensional sonic images combined with incredible detail, ruler-flat frequency response and rich, full bass. Because the StudioMonitors are true full-range speakers with extended low-frequency response they deliver superb performance both as stand-alone speakers and when combined with separate subwoofers.
Monocoque, Non-Resonant, Low-Diffraction Cabinet
The cabinet of a loudspeaker plays a large part in its sonic performance. Diffraction, or the secondary radiation of sound caused by cabinet edges, grille frames and other protrusions, can color the sound of a loudspeaker. The design of the StudioMonitors reduces diffraction to an absolute minimum by flush mounting drivers on extremely narrow baffles with radial edges, which are covered by a frameless grille "sock."
In addition, the resonant vibration of a loudspeaker's cabinet walls and baffles can also impart unwanted coloration. The Definitives' monocoque cabinets are constructed of high-density medite with 1" thick front and rear baffles, foam damping pads and internal braces. This virtually eliminates resonant cabinet coloration which could otherwise interfere with the pure sound produced by the high definition drivers.
High-Definition Cast-Magnesium Basket Drivers
The StudioMonitor 450 utilizes a 6-1/2 inch high definition cast basket bass/midrange driver for significant performance advantages in the areas of bass reproduction, lifelike midrange clarity and dynamic range. This sophisticated bass/midrange driver incorporates deeply drawn mineral-filled homopolymer cones, combined with butyl rubber surrounds and dustcaps, high temperature vented voice coils and massive magnet structures. This combination of features assures high definition, superb transient response, high efficiency, high power handling and extended bass response. In addition, they are assembled utilizing an aerodynamically designed, magnetically inert, cast-magnesium basket to minimize internal reflections off the back of the cone and preserve structural and magnetic integrity under all conditions.
Moving Coil Pure Aluminum Dome Tweeters
The moving coil dome tweeters Definitive developed for the BP7000 Series are used in the StudioMonitor 450. They utilize a specially annealed pure aluminum 1-inch dome, suspended by a silk surround and acoustically loaded by a precisely configured phase plug/lens, engineered to assure perfectly controlled, absolutely linear movement. This results in velvety smooth extended response (beyond 30 kHz), greatly reduced distortion, improved transient response, wider dispersion and notably higher definition. Magnetic fluid damping is incorporated for ultra high power handling.
Phase-Coherent Linkwitz-Riley Crossover Networks
The crossover network of a loudspeaker is the real heart of the system, as it is responsible for perfectly blending together the sound of the various drivers into a musically seamless whole. The sophisticated Linkwitz-Riley design used in the SM450 equalizes the drivers for linear phase and frequency response. This preserves the phase coherence, transient response and dynamic integrity of the signal for absolutely lifelike music and home theater reproduction in your home.
"fuller range, greater detail and an overall warmth..."
With the Studio Monitor 450, DefTech has given serious music lovers something that (in my opinion) has been missing for a while in this age of multi-speaker surround systems: A full-range bookshelf speaker.
My living room system was something of a compromise with the previous speakers used- which indeed were fine speakers, but (as most bookshelve-types do) have a bottom range down to about 55Hz. When I read the 450's specs, I was intrigued- especially since one of DefTech's authorized dealers was discounting them for a period of time. Included was a ten-day return period. Needless to say, no return is even being contemplated.
As the brochure reads, the speakers will sound good right out of the box. But they suggest that after a break-in period of between 20-40 hours they should sound even better. This is very true.
After about a week, today I noticed on a couple of recordings (classical/orchestral) that they're really starting to "bloom." There is a fuller range, greater detail and an overall warmth that they're producing in comparison with older bookshelfs that I was using. They're also bringing out just how good my "mid-end" Marantz CD player & Onkyo 2-channel receiver are.
As a full-time musician, I am very pleased with the Studio Monitor 450's. At the stated retail price, they're definitely worth it. At any discounted price, they're an astonishingly good deal...

I have had Definitive BP8's and have loved them for years, and was looking for speakers to replace my B&W's in a different room. I went to a showroom in Manhattan which was a dealer for both Company's, among others. So I got to listen to my "trusted" 602's, and compare them to the Definitive 450 monitors. I was immediately struck with how open and lifelike the DefTech 450's were, whereas the sound coming from the B&W's sounded like it was coming out of a box. All those years I had thought so highly of the B&W 602's, and the Definitive 450's really put them to shame. The engineers/listeners at Definitive have done music and movies such justice, their speakers make you excited to re-listen to all your music/movies. From the highest chimes, to the lowest upright bass, these speakers just do it. I'm using them with the supercube 3, the smallest one, which blend so well, but you will still get a lot of bass from the speakers themselves. A++

"performance to price ratio can't be beat!!"
i currently use klipsch rf-7 and matching center for my system...my new place is smaller so I needed something with a smaller footprint not smaller sound. The def tech studio 450 definitely fill my needs and more....the sound with music was dynamic and rich at all levels no matter where I sat...unlike my directionally sensitive klipsch speakers. I am very happy with my purchase and the performance to price ratio can't be beat!!
