What does an active crossover do?
An active crossover is a device that modifies an audio signal before the amplifier. It works on line-level or preamp signals only. Active crossovers combine op-amps, resistors and capacitors to alter different frequency ranges of the signal.
Does an active crossover need power?
Active crossovers always require the use of power amplifiers for each output band. Thus a 2-way active crossover needs two amplifiers—one for the woofer and one for the tweeter.
What is the best crossover for speakers?
Set the crossover point around 10 Hz below the lowest frequency your speakers can produce without issue. (keep in mind that the most common recommendation for crossover frequency is 80 Hz). Once again, play some music. But this time, slowly turn up your receiver’s volume until you hear it begin to distort.
Does a full range speaker need a crossover?
Probably the biggest difference with fullrange speakers is there’s no need for a crossover (although possibly a single resistor to tame an unruly peak) and phase alignment isn’t a problem between drivers – since there’s only one.
How important is the crossover in speakers?
Crossovers optimize loudspeaker frequency response In all loudspeakers, the crossover is essential for creating an accurate frequency response. Frequency response is generally shown as frequency amplitude measured in decibels. Depicted graphically, frequency response is usually shown as a line.
How do you connect an active crossover to an amplifier?
Connect the amplifier output to the crossover. Using speaker wire or RCA cables (depending on your stereo system and crossover unit), connect the crossover to your amplifier just as you would a speaker. The crossover should be the last piece of equipment in the chain before the speakers.

What is an active speaker crossover?
– Small bookshelf or satellite speakers (4-5 inch woofer): 150-200 Hz – Medium sized bookshelf speakers (6-8 inch woofer): 75-100 Hz – Large floor-standing speakers (10-12 inch woofer): 60-80 Hz – Very Large floor-standers (15+ inch woofer): 40-60 Hz
What is an active crossover?
Active crossover. An active crossover gets its input from the pre-amp and sends the signal to multiple outputs, each connected to a power amp. Each power amp drives only one driver. As the passive crossover is removed out of the power circuit, the amp has now full control over the driver (damping). The crossover is working on line level.
What is active crossover car audio?
Active (electronic) crossovers An example of an external (add-on) electronic (active) 2-way crossover.
What is active electronic crossover?
Electronic crossovers are sometimes called active crossovers. Both refer to the same thing: line level crossovers that are used between preamp and power amp. We also have passive line level crossovers; these also operate at low level (between preamp and power amp) but only use capacitors, resistors and inductors and have no power supply.
