Acoustic Research M5 Holographic Imaging Speakers. Pair of Floor Standing Speakers. Right and Left Speakers. MADE IN THE USA! ACOUSTIC RESEARCH M5 Holographic Imaging Speakers have the following features. Dynamic 3-way and biampable. Tweeter: One 3/4” (19 mm) ferrofluid-cooled, Ultrawide dispersion, Low-resonance cavity-loaded (hollow pole piece for lower resonance and lower distortion) aluminum-dome tweeter (1.3 Khz free-air resonance). Midrange: One 5 (130 mm) very long-throw carbon/mica filled polypropylene cone midrange with natural rubber surround. Woofer: One 8” (210 mm) heavy paper cone woofer in a bandpass, filtered-acoustic-suspension topology with one loading side sealed and the other a resonance chamber with turned, double-Q overlapping vents. Crossovers: 3.4 kHz, 12 dB/octave highpass into tweeter (> 1 octave above resonance), employing mylar capacitors; 150 Hz bandpass plus 6 dB/octave high-current capacitor; inductor added for impedance matching. Optimum-phase driver overlap and baffle offsets Frequency Response 48 Hz-20 kHz 3 dB anechoic axis response. WHAT IS HOLOGRAPHIC IMAGING? It’s the vivid recreation of the sonic space on a recording and the exact positioning of instruments and singers within that space. ANGLING THE WOOFER UPWARD. This projects smooth, flat sound at the critical crossover point directly toward your ear and ample hall-simulating midrange reverberation throughout the reflected sound. Imaging is no longer appreciated just in the “sweet spot:” The asymmetrical offset of the tweeter on its baffle improves imaging over a wider listening angle. BETTER GEOMETRY= BETTER IMAGING. Unique narrow cabinet baffle minimizes diffraction and reflection effects for superb stereo imaging. New low frequency design delivers more energy from a small cabinet and maximum performance in any location. AR’s ultrawide-dispersion, louvered 3/4 (19 mrn) tweeters produce precision localization on axis, along with treble airiness throughout the room. It’s the best of both worlds. BETTER “REAL WORLD” FREQUENCY RESPONSE. Frequency response measured in a real, typical living room shows serious smoothness across the crucial, ear-sensitive midrange and upper midrange. This simply means better and more accurate sound. WOOFERS WITH POWERFUL BASS. Due to the new and improved woofers, these speakers demonstrate effortless bass performance. Rubber roll surrounds ensure the greatest excursion possible for the cone, combined with very low resonance. The acoustic suspension system that AR invented then maximizes the bass performance from the compact cabinet. DOME TWEETERS FOCUS CENTRAL STAGE. They project unconfined sound into the room rather than localizing it to the speakers. The result is a clear central stage that’s more enjoyable. Several types of dome materials have been used, each making its own special contribution to the sound. An all aluminum dome that’s ferrofluid-cooled for low resonance. WHEN IS A CABINET NOT A CABINET? When it’s actually a performance component. The striking cabinet shape is unusually rigid and strong, minimizing panel talk. Non-parallel cabinet walls reduce internal standing waves that affect cone motion. So the loss of musical detail is minimized. Holographic Imaging crossovers are of minimalist design to reduce power loss and ensure the smoothest sound. The Biamping capability means cleaner playback with more power available for the potent bass and midbass. HIDDEN WOOFER SYSTEM HAS SLIM PROFILE, ASTOUNDING BASS. Superior deep bass from a smaller enclosure that’s been AR’s driving philosophy for four decades. In the M5, the enclosure means a smaller footprint in your living room, too. And with filtered acoustic suspension, it gets increased efficiency for the digital era. The control of a sealed woofer side with the sensitivity of the vented side is the best of both worlds. Dual vents at different spacings, furthermore, blend smoothly for accurate bass reproduction.
