Magico A-Sub subwoofer (x2)

Subwoofers are increasingly part of the ‘package’ even up in the stratosphere of Wilson’s top flight offerings. Magico’ a A-Sub adds a near affordable proposition together with extensive on board DSP that reaches beyond the normal gain, phase and low pass filter cut-off, employing, I believe, Hypex class D amplification and DSP engine. In my own case, I have managed to tame the significant +/- 10dB swings of my mains over the first 3 octaves utilising 2 passive 18 inch subs, MiniDSP 2x4HD and two mono amps. The Magico product possibly enables removal of the MiniDSP and amps as it integrates, pretty much, all the needed functionality.

No doubt many will recoil at the suggestion of post DAC (re) digital conversion but the allure of ‘mode manipulation’ is worth exploring - after all, how many of us use expensive full range speakers in non—optimal conditions - for example open plan living arrangements? In order to facilitate the calculation of beneficial gain, phase and equaliser settings, I have used the excellent ‘multi-sub optimiser’ program to great effect - a free software package, noting that a much smoother response is possible utilising low pass, phase and gain alone with no recourse to any further parametric equalisation.
