I relly think you should think more out of the box and also give Meridian some credit for what whey're doing
First of all, as far as I know there are no applicable standards about how to hook up a sub using digital connections, it would be a good thing if such a product can be step along the path to get such a standard
Second, this can only probably be used with their speakers because of the one above
Third, most all other subwoofer makers are making suboptimal products when you use DSP because they requirte you to go digital, then analog, then digital and then analog again and this is clearly not optimal with all these conversions which also create time delays that mkay not be catered for completely
Price / performance is not at all very good but Meridian is showing some sort of creativity here and they deserve credit for this.....
