Default Full range with low pass high SPL sub?

Could a full range like the Mark audio 10.2 be run through a potentiometer to control output and matched with a sub of equal or lesser efficiency on a low pass filter say Hz. Could you in theory balance the output of the Mark audio 10.2 with the pot to the subs low pass output and have a complementary system? This would be in some sort of tower unit, of course the two drivers chambers would be separate.

In theory, yes you could.

In practice, very few people would do it that way: especially for a high-SPL application, the crossover parts required will be extremely large, and therefore expensive. Potentiometers also have low power handling compared to, say, a ceramic or aluminium clad resistor.

The alternative is to use a second amplifier to drive the woofers, and put the crossover before each amplifier, ie, create an actively crossed over system.
The parts are much cheaper than a passive (after an amplifier) crossover, regardless of if you wanted to go fully active (with op-amps and stuff) or passive line level, which involves a combination of resistors and capacitors to alter the signal going into the amplifier.

an active crossover would make this a much easier project.
And they are fairly cheap ($100 used).
