visionik is a very terrible car audio company, i personally bought two of there 800 watt subs, 12's, an there amp to match them in there own sealed enclosure, it was like 400 bucks for my girlfriend for christmas (they were pink she loved them!) lol, but i took out the kickers i had at the time, put those subs in, and i couldnt hear them over my front stage (infinty kappas 6.1) and they were horrible, can do MUCH better!
I had 2 15inch dual 6 ohm subs, 400rms each. After 3 days of use one of the subs voice coils went on me. Now i have 1 dual voice coil sub and 1 single voice coil sub. Now my amp is too powerful to just run half of the sub, and where I bought them from doesn't take returns or exchanges. Don't buy them unless you know you can return them.
actually here in the U.S. most companies will sell you a replacement cone set for like 50 bucks, i dont know how mucht hat is in pounds? lol, but ive repaired several and its a very simple, jus tediius task lol. but were talking about voice coils not cones
thats really cheap, but when we pay over here, we pay most of it for the postage. But DD recones are only done by specially qualified ppl trained by dd in the US. Thats why I can't call them and ask them to sell me the recone kit. I dunno how much of this is true but thats what I was told.
