I saw them on a few different sites. Saw some "display models" for around $149. Woofer setc has them for $159 ($230 off they say).
I managed to win an auction on ebay for a set and I got them for $102...not too shabby - now I just have to wait to see how much I have to pay for shipping
So, did you like these woofers? I have an older Porsche 928 that came with a 10-speaker set up and I want to drop the hd 6+'s in the spot where they had a 6.5" "woofer" originally. I think it is more of a high midrange woofer, so hopefully the hd 6+'s give me a little more bass.
I also have to get a 2-channel or mono amp to run these new woofers (I doubt the decks amp will work them).....but I have no clue what to look for "wattage-wise". The search begins.....
