nope, seen quite a few blaupunkt head units though, quite good... different and unique...
the information on the sub on their website says that the 380 sub (1000watt rms) has a frequency response of 25 - 1000hz, but like every other place, they dont state a price, they also dont say shit about it being either a dual magnet, dual voice coil, the strength of the magnet etc...
normally that isnt stated for a reason, so i can only assume that it is a single magnet single coil, meaning, if it is powered correctly, it will burn out the coil pretty fast...
due to lack of info, and better options out there, i wouldnt pay more then 300 for one of those, even then, i know better subs to buy...
and as for your contract, ANYONE and EVERYONE can and should get discounts on electronics... never buy the sticker price, they are rediculously priced... if they say they cant give a discount (and its not on special) ask what you have to do to get one, if they say they really cant, f**k em...
