Put the driver in a smaller than recommended box and use a Linkwitz Transform?
Nope. No active circuitry, no extra amp, any alignment you wish. Keep tryin.'
Quite agree. And that's what I did with my speakers. Found the filter functions that worked best for my speakers and room via active (DSP), then built a passive implementation of that. They aren't 100% identical, but are so close as not to matter.In any case, if the overall transfer function of an active and a passive crossovered speaker is the same, they'll sound the same, and one can do either to achieve it. No magic.
That really should be the wrap-up of this thread. It sums it all up nicely.There's no magic in speaker engineering, just art and craft. The art is choosing the transfer function (which includes polar patterns and the way the speaker is configured to interact with the room). The craft is implementing the bits and pieces to achieve the target.

You can make a special EQ to shelve out the extra loudness of the woofer.
Again.... I'd say YUK.

So would I. One more guess.
Hint: you haven't exhausted the list of passive components.

Resisters are the only passive crossover elements that are not supposed to be reactive, and therefor would effect the entire range of the woofer evenly.
Passive and reactive are not opposites. For example, a capacitor is reactive and passive. One more, James!
I never said that or implied that! I know that resisters, capacitors and inductors are ALL passive elements. Resisters are not supposed to be reactive. That is what I said!
OK, so one more try- how do we deal passively with a woofer to match its spl with a less sensitive mid and tweeter without affecting the efficiency of the alignment? Clearly, a series resistance won't fulfil the challenge.
Get used to a tubby sounding speaker.

Not if you come up with the right answer. Stop thinking about resistors. Keep whatever box and alignment you like. C'mon, dude, I have confidence in you, which is more than I can say for Carl.
BAWP!!!!! No, sorry, that changes the alignment and the efficiency. But thanks for playing our game and we have a home version of Guess The Crossover for you, along with a year's supply of Swanson Frozen Dinners. Swanson, for when you're too busy to cook.
The right answer is: step-down transformer or autotransformer.

Ok that's it. No Bybees for you mister.
Using a transformer is a bad idea. If the woofer, mid and tweet all are the same nominal impedance to start with then that will get all screwed up with a transformer on the woofer. The only way to compensate for that is to give the low end current another path around the woofer. Bad idea! There goes your SPL!
The nice thing about multi-way amplification and active crossovers is that every amp gets to work at its peak performance with as little non-sound-producing power consumption as possible.
In general power amps tend to increase in distortion as they increase in power toward their own limits.
I'm surprised no one has commented on an actual example of everything I've stated in this thread.

All three sections have different SPLs and even different nominal impedances.
