RIZ Posted June 20, 2016 Report Share Posted June 20, 2016 Ascendant audio havoc 12" dual 2 ohm in a ported box built by jaspal dole tuned to 30hz sounds very nice and musical but can get low as well. Sub is in good condition just has one slight nick on the rubber surround but doesn't effect it in anyway. Dimensions for the box are 32"x15"x15" Price for subwoofer and box is £220 Also have a gladen audio spl-1800c1 amplifier that was used to power the havoc specs are @ 4 ohm mono 1x 965 Watt @ 2 ohm mono 1x 1760 Watt @ 1 Ohm mono 1x 1760 Watt Price is £220 for amp If sub and amp is purchased together I'll let both go for £400 Link to comment Share on other sites More sharing options...
