These are actually the Studio configuration so the total cost is $70,000/pair. They are the same main module and studio sub reviewed in Stereophile, they just don't have the professional sub. They are said to sound identical, the difference being the pro configuration is capable of higher SPLs in large rooms. The Spectron amps can deliver 300 watts into .1 ohms so they will be able to drive these speakers with no problem. We will also be using the remote sense speaker cables made by JPS Labs specifically for the Spectrons, which extend the feed back loop out to the speaker end of the cable.
