I just found a pair of older Eminence Delta 15 in drivers. (They were sitting on a shelf along with a bunch of other speaker parts.) A few years ago you sent me the plans for Theater 4 PI's. I'm feeling nostalgic and want to build a pair of T 4's like I used to own. I cant find my copy of the plans. Could you please resend them. They were from the series before the zobel circuit was added. Thanks.
