1 MINI-METHOD AMP UPGRADE Mk.II [Rev-A] SUBWOOFER AMP

2 Our Method subwoofer (now out of production) is legendary, one of the most musical subs ever, and this despite the rather cheap plate-amp we matched up with it. The amp sounded good enough but it was a typical subwoofer plate-amp. Good news though, we have made a direct replacement that is based on the subwoofer amp we developed for our Defi nition Mk.IV loudspeaker, featuring the excellent Hypex UcD 400 DS4.0 V5 amp module and expanded controls and signal processing. Sorry, no refund for the old one, it s not worth the shipping but you can send it back to us for recycling. This upgrade kit is only available direct from Zu.
