Actually I do have the link and the price. They are selling for just about 260$ for the bare kit without cabinets plus shipping. Thats the two drivers each /the crossovers and the stuffing for the aperiodic vent.They are upgraded from the originals and still use the ten" woofer crossed low over to the tweeter. If I didn't love my Pi's I would buy these in a second; make that a New York Second!
But the Theater 4's are pretty hard to beat; although I have yet to try the mods Fred suggested.
