Pentagon Alpha Speakers Love the Speakers. Any owners advice would be helpful.

Hello I just purchased a pair and looking for any specs or information on these speakers. The only thing I could find on the internet is that they were sold in 1999 have in each speaker a pr, 2-5in woofs, 1in twtr, and weigh 140 lbs. They retailed for $5,000. Any info would be appreciated. 

Best Regards
