I think I'm getting a clue here....This isn't for a soundsystem, it's a scale model of some machine or other, and you're putting a very small set of speakers into it because you want it to make the same noises as the full-sized version?

If that's right, then this might be much simpler. You probably don't need high-fidelity speakers to reproduce machinery clanking or engine noise. Run that bass-mid driver full-range, and connect up the tweeter with a 1uF cap in series. Add a 4 or 8 ohm resistor before the cap if that makes it too bright. That will start bringing the tweeter in at about 15kHz assuming it's 8 ohms, which might seem high - but the response shape of most tweeters is far from flat and the effective acoustic crossover point will be much lower.
