Different drivers in the same box

[Mara Scott]

This generally isn't done, but, does anyone have any experience on the pros and cons of putting multiple drivers in the same box that are not exactly the same model? I would be curious to hear about your experiences with this.

My gut feeling, is that it isn't a huge problem, and may potentially the speakers may be able to compliment each other. Downside being this approach does not have a mathematical explanation, especially if a tuned box

My experience is that mismatched drivers can sound great in guitar cabs, for example putting one greenback and one blueback in an AC30.
For bass applications the frequency cancellations and different power ratings usually add up to sounding worse than matched speakers.

It can work just fine, and in fact can allow a designer to do things that simply can't be done with a single driver model.

That said, different driver types should not share a common air space, whereas identical drivers can.

I was assuming OP meant replacing some of the speakers in a pre-existing cab with different ones.
If the system is designed that way in the first place it's a completely different story.
