Active crossovers aren't as widely used as passive crossovers, however, because the equipment is much more expensive and you need multiple amplifier outputs for your speakers. These enclosures are less efficient than other designs because the amplifier has to boost the electrical signal to overcome the force of air pressure. The air will always move to equalize pressure levels, so the driver is constantly being pushed toward its "resting" state -- the position at which internal and external air pressure are the same. The force serves a valuable function, however -- it acts like a spring to keep the driver in the right position. The disadvantage is that there is no air pressure difference to spring the driver back into place, so the sound production is not as precise. Both movements create pressure differences between the air inside the box and the air outside the box. Crossovers and drivers can be installed as separate components in a sound system, but most people end up buying speaker units that house the crossover and multiple drivers in one box. Rental apartments, large or small, are great when you are starting out, are starting over, or want to live in a neighborhood for a while before buying that castle in the sky.
