Hi-
I am building a system for a friend based on the drivers he says "must" be used. Unortunately the tweeter is rated at 90 dB/W/M, while the midbass is either 94 db (he has another driver at 89 dB), and the sub is rated at 95 db. As you can see, this is a two way application with a sub. This is an all active setup, using only impedence equalization circuits before the driver. All amps are the same. The question is, will we run into a problem of level mismatch between drivers at different levels of amplification? Does it even make sence to use sensitivity-mismatched drivers with an active system that uses identical amps?
Thanks!

Hi Amo-
Don't know why no one has answered sooner, but this is one of the best reasons to go active X. Power each driver as it needs, no choking to the lowest efficiency.
Tune for the room, and the music....lets each driver be the best it can be....ideal, really.

The usual approach would be to adjust the gain of each amplifier so that the all drivers receive the correct amount of power. Given that this would appear not to be an option to you, you would have to provide gain / cut to each of the line level signals immediately after the active x/o / prior to the power amplifiers.
