They're a three way system, in optional walnut or oak veneered chipboard. Inside live three drivers, a 10" LF radiator, 8" midrange and ¼" 'superdome' (as EV call it) tweeter. Impedance is given as a nominal 8 ohms (suitable for nearly all common amps) and the overall size of the units is 61.5cm x 35cm x 27.5cm. This size makes the Link 9's halfway between floor standing and large shelf mounting units — ideal in dimensions, therefore, when used in a small control room environment. They are light to move around and very well finished. Frequency range from the spec, sheet is a very impressive 39-20,000Hz ± 3dB from 47-18,000 Hz. In effect a considerable range to offer at such a low retail price — especially given the efficiency of this combined three way system.

The key to the design of the Link Series speakers (there are Link 7, 8, 9 and 10 models) lies in the design theory of an Australian acoustic scientist by the name of A.N.Thiele (pronounced Teel). His ideas lead designers away from normal bass reflex enclosures and normal Acoustic Suspension designs towards a different type of system which they have dubbed 'optimally vented design'. The theory behind all this is well beyond the reach of most of us and would take too long to go into here, but suffice it to say that Thiele's work is genuine and much admired in speaker design circles, even if not totally agreed upon by all makers and designers. In practice, (following Thiele's ideas) then one would expect the Link 9's to be A) louder than most speakers and B) with a better bass response.
