I am looking for info on the "rules" so to say, about the effeciency of a midbass/woofer and a tweeter.
When selecting drivers for you speakers, do you need to keep the effeciency as close together as possible? Or is it all a matter of personal taste in sound.
Any help is appreciated. If there are other thread please direct me there although searches on the subject have come up empty.

Hi Ryan,
Methinks the rules of what you speak are really up to you.
If you get a tweeter with a higher efficiency and you like the sound, leave it. If you feel it's a bit bright, you have the option of adding resistors to attenuate it. These resistors can be static or you can use a variable resistors such as L-Pad's.
If you have a woofer that is too strong you will likely have to use your treble control or equalizer to attenuate as adding resistance loads to a woofer "kind of " defeats the amplifier power. Most of the power in audio is used up in the bass.
Do you know what your tastes are as far as the brightness is concerned?
I thought I liked it bright until I got a 108dB @ 1W compression driver behind a horn. I had to add an 8 ohm resistor in series and then a 5 ohm in parrallel just to bring it down to a decent level even though the woofer is high also at 97 dB @ 1W
I think you are best to get a tweeter that is equal to or somewhat above the woofer so that attenuation, if required, can occur within the high frequencies.
Hope this helps

In addition to what Cal says, one of the most important issues in a better design is how baffle step compensation will be accomplished. If you are cutting down the upper range of a midwoofer for BSC, then you can effectively use a tweeter with a lower efficiency. If you are using multiple midwoofers, you must ensure your tweeter will match their effective (including crossover)sensitivity.
