The Diamond 8 series is the result of over three years intensive research and development into virtually every aspect of acoustic design. Firstly, the tweeter in all models is a 25mm textile dome, ferrofluid cooled unit powered with an ultra-strong neodymium magnet for the fastest, most accurate response International Audio Group has ever achieved. Next, the woofer cone is made from a bi-directional KEVLAR weave - self-damping in nature, reducing resonant frequencies to virtually negligible levels. The impetus for rapid movement here, is a dual layer, vented voice coil which transmits the signal information with the highest levels of accuracy. The cone is mounted on a nitrile rubber 'Flexaural surround rim'. A profiled phase plug improves the off-axis performance to project an excellent stereo image across a wide listening area. All the stereo models are front ported to enable positioning close to a back wall. Gold-plated bi-wire terminals are used for connection and you should take advantage of the increase in openness this offers, even if using an amplifier with single connections. The final test though, of any loudspeaker is not how much technology is used in the constituent parts, but how these react together to form a coherent package. It's more about the kind of music synergy that can be created between the various elements to ensure the overall result is much more than the sum of the parts. It is this elusive element, the 'musicality' that separates the Diamond 8 from all the competition and you will not believe the results.
