I'm about to build up a Powered sub for my Home Theater and was about to order a Shiva/PE250 from Kyle at Acoustic Visions, but I then noticed that the BluePrint 01 series drivers were being updated. I know the older SVS CS series drivers were similar to the 01 Series, and I'm wondering if the new 1201's will be similar to the new DB12's sold in the CS+ series by SVS. I tried E-mailing BluePrint a week ago, but havn't heard back, which isn't a good sign. Does anyone have any experience with the BluePrint 01 series subs, and what sort of enclosure/port sizes will I be needing for them to match a shive in a 100L enclosure. Thanks for any help guys, help me get this goin so I can do some ordering!!!!
