Comment: The IRS was designed to be an internal reference system at Infinity, but the demand of the public for such a state of the art speaker system was so great that Infinity decided to sell them to people with enough money. The IRS V is just a newer version of the original IRS. As you can see the main difference is the newer bass driver which was introduced with the Kappa series.
Click here for a technical sheet of the IRS Beta with schematics of the crossover and the servo control unit. The servo control unit from the IRS V should be the same.
A technical sheet with (sadly, without crossover schematics) can be seen here.
