For any prospective nearby buyers, viewing and testing the speakers are welcome. Sensitivity (2.83 V/1 m): 86 dB.
Frequency Response: (+/- 3 dB) 32 Hz - 25 kHz. Internal Cabinet Volume: 33 litres.Dimensions (W x H x D): 205 x 980 x 295 mm. Crossover Slope: Woofer 6 dB/octave; Tweeter 6 dB/octave.
Pure aluminium wire voice coil. Dual 17 cm with die cast chassis. One piece moulded MSP cone. 75 mm long throw pure aluminium wire voice coil wounded on aluminium former. The crossover is impedance corrected.
Inductors wound on "air cores". Capacitors with low loss dielectricum. By employing a double-magnet motor system with ultra-compressed Ferrite magnets, dramatic musical passages are reproduced without compromise. And with increased cone excursion, even the most powerful transients are delivered without compression. Another Dynaudio exclusive: The cone diaphragm with controlled rigidity is manufactured from Magnesium Silicate Polymer (MSP) - a material essential to the unique Dynaudio sound.
This complete motor assembly is built into a torsionally rigid die-cast aluminium basket, which has been optimized to eliminate air turbulence and resonance and the adverse effects of such. The extremely smooth and incredibly detailed high frequency reproduction characteristic of Dynaudio is guaranteed by the T 380 soft-dome tweeter, which features Esotec+ technology. For the upper-range in the Focus 220, this called for the employment of Neodymium - one of the most efficient but also most expensive magnetic materials for loudspeaker construction.
With the tweeter's solid metal face-plate firmly attached to the cabinet by no less than six screws, any resonance is eliminated. Such a secure, neutral foundation is simply not possible by using light-weight plastic cabinets or loosely mounted drivers.
