You can get a crossover, which sends only ideal frequencies to the individual speaker in the system.How much greatly depends on what you're looking for, what options, and what brand. It can be from 20 to 2000 or more, just like amps or subs.You would need one if you want to modify the signal.

You will have more options to adjust the sound to your satisfaction and in a more convenient way, as many of the present processors can/must be set from a portable computer.
