It's probably not just a case of the Aktiv board working with non-Linn speakers. It probably will only work with one specific Linn speaker system. I don't know about recent years, but at one time Linn Aktiv crossovers were designed for one specific Linn speaker model. Thus, if you had, say, a pair of Linn Kaber speakers that were "Aktiv" and you upgraded to the Linn Isobarik speakers and you wanted to make them "Aktiv" as well, you had the supreme joy of replacing your Linn Kaber Aktiv crossover (costing, say, a mere $2000) with a new Linn Isobarik Aktiv crossover. (The boards installed inside of the amps would probably have run less, since you didn't have to buy the Aktiv case or the power supply. On the other hand, I wonder if the older stand alone crossover, despite the higher cost, wouldn't have been better sounding since it had its own power supply.)
Supposedly, the idea was that by making a specific crossover, Linn could tailor it for a particular speaker system, and thus maximize the performance in a way that one couldn't if making a generic active crossover.
Of course, there is one other question that comes up--given that the included speakers are B&W. Assuming that the speakers were used with the Klout, then I'd guess that the amp was probably already modified back to non-Aktiv status, but the label was left in place. I'd seriously doubt that Linn would have ever made Aktiv crossovers for anyone else. (Keep in mind that when the Klout was released, they had a complete line of speakers.) Thus, to check to see if the Aktiv board is in place would require actually openning up the amp and checking to see what's in there.
