Why are the Infinity IRS, Reference 1b, Beta ect speakers passive on the mids and highs?


I would like to know why all of the classic Infinity's and most other brands use passive crossovers for the mid to high transition? I don't think it was for cost and that level. Is passive better? Has anyone compared both to know which is better?

I don't think adding another amp would be too much in cost or space ...
Well then, why not give it a try and report back to us?

I think it's a practical matter. How many amplifiers do you want to have in your system? While it makes practical sense to separate the bass frequencies from the rest of the speaker system - especially when the manufacturer has already committed to using separate bass towers, as in the RS-1 and various IRS systems - there's less advantage to be gained by separating the mid from the high frequencies.

Separating the bass and using an active x-over also allows use of a servo system for those frequencies, which Infinity did with great success. I don't think it's feasible to use a servo on higher frequencies, however.
