Send the subwoofer the same signal from the pre-amp, either by using a 2nd set of pre-outs or an unfiltered loop-back from the monitors. Then set the low pass filter on the subwoofer to blend with the natural roll-off of the powered monitors - usually around 60 Hz is a good starting point but trust your ears.

Look at the back of your subwoofer, then set the low-pass crossover at least 10Hz higher than your main speakers’ range. This range is the starting point when configuring your crossover. If your center speaker can produce 80Hz to 120Hz, then you want your low-pass crossover to be anywhere close to 90Hz.

Set the crossover point 10 Hz higher than the low end of your speaker’s tolerance range. If you don’t know the frequency range of your speaker, use a subwoofer matching tool. Listen for smooth transitioning between the subwoofer and the speakers. The blending should sound clean and seamless. If there’s a bass bump at the crossover ...

You must then set the subwoofer crossover on the sub itself to route the low frequencies to the subwoofer. Try a setting of about 80 Hz to start, depending on how large or small your main speakers are. If they are very tiny satellites, you may want to raise the crossover frequency to 100 Hz.

Using the lower frequency response of your speakers, you can set the crossover point by adding about 10 Hz to it. You can use a subwoofer matching tool to check the speakers’ frequency, the speakers’ manual or you can also check the range online for the brand you are using.

There are basically two ways to set up a subwoofer crossover with your main right and left loudspeakers. Each of the two schemes has advantages and disadvantages. Which one will work best with your particular system depends on many factors, including your room, your power amplifier, your subwoofer and, lastly, your main speakers.

Setting the correct bass management on receivers and processors is essential to getting the most out of your audio system. While some systems recommend 80Hz (the standard THX setting for Select and Ultra2-based systems) this is not always the best ...

The crossover frequency is the frequency at which your amplifier should stop responding to the signal from your subwoofer or tweeter. Ideally, you would set the crossover frequency as high as possible with the amp still producing sound. However, this will depend on what the amp is capable of.
