Ok so my friend has these speakers I've never heard of called Virtual Technologies. He's got two 12" subs in the virtural technology box (comes w/ the speakers) and he tears it up at competions. I look all over the internet for these suckers and can't find a damn thing except their shitty website that has been under construction for 390493 years. Well i find out one day there is some schwagg shop here in Canton that is license to sell these things. I go to this shit shop to see these things. The guy has them hooked up to a 30W amp and a tape player, i asked to hear them n when the tape was cued up and played the speakers blew me away. They're the most efficent subs i've ever seen/heard, they hit the lowest notes i've ever heard and with only 30WATTS Pushing them. They have two voice coils which makes them extra nice. This is something someone should consider if they want a serious sound system. 1 !2" can blow away most 2 12" w/ less wattage and better sounding bass. The bitch is finding them. their website is
