Ground Zero was well known here in the states back in the late 1990's. Those GZ Nukes are serious freakin subs. I have heard one 15" Nuke about 10 years ago and it was off the hook. Easy 150 db with one 15 in ported enclosure and some major power on the sub. There was a number of guys on these online forums that ran these subs but things faded away. I think the whole carver deal with these subs might have ruined it here or did something to lose popularity, these came out around the time the earthquake subs were out, they both had fat surrounds and crazy xmax and could rattle your fillings loose. If there is another similar subs like the tc sounds I would get that instead of paying the high price from overseas but if you could one of these subs you in for a serious treat and you will be different! And now they have the plotonium series which wasnt out before, I would like to see how those pound!
