As an audiophile, you’re likely no stranger to the world of active and passive speakers. While active speakers have their advantages, there may come a time when you want to convert them to passive speakers. But why would you want to do that, and how do you go about it? In this article, we’ll delve into the world of speaker conversion, exploring the reasons behind it and providing a step-by-step guide on how to make active speakers passive.
Understanding Active and Passive Speakers
Before we dive into the conversion process, it’s essential to understand the difference between active and passive speakers.
Active speakers, also known as powered speakers, have a built-in amplifier that powers the drivers. This means that the amplifier is connected directly to the drivers, and the speaker is self-contained. Active speakers are often used in professional audio settings, such as recording studios and live performances, where a reliable and consistent sound is crucial.
Passive speakers, on the other hand, rely on an external amplifier to power the drivers. This means that the speaker is not self-contained and requires a separate amplifier to function. Passive speakers are commonly used in home audio systems, where the amplifier is often a separate component.

- Power supply: The power supply is the component that powers the amplifier.
Identifying the Crossover
The crossover is a critical component in the conversion process. You’ll need to identify the type of crossover used in your active speaker. There are two common types of crossovers:
- Passive crossover: A passive crossover uses passive components, such as capacitors and inductors, to divide the audio signal.
- Active crossover: An active crossover uses active components, such as op-amps, to divide the audio signal.
If your active speaker uses an active crossover, you’ll need to replace it with a passive crossover.
Step 2: Remove the Amplifier and Power Supply
Once you’ve identified the components, it’s time to remove the amplifier and power supply. This will involve disconnecting the wires and removing the components from the speaker enclosure.
Disconnecting the Wires
When disconnecting the wires, make sure to label them so you can identify which wire goes where. You’ll need to disconnect the following wires:
- Speaker wires: The speaker wires connect the amplifier to the drivers.
- Power wires: The power wires connect the power supply to the amplifier.
Step 3: Install a Passive Crossover (If Necessary)
If your active speaker uses an active crossover, you’ll need to install a passive crossover. This will involve soldering the components together and connecting them to the drivers.
Soldering the Components
When soldering the components, make sure to use a soldering iron and follow proper soldering techniques. You’ll need to solder the following components:
- Capacitors: Capacitors are used to filter the audio signal and divide it between the drivers.
- Inductors: Inductors are used to filter the audio signal and divide it between the drivers.
Step 4: Connect the Drivers to the Crossover
Once you’ve installed the passive crossover, it’s time to connect the drivers. This will involve connecting the speaker wires to the crossover and the drivers.
Connecting the Speaker Wires
When connecting the speaker wires, make sure to match the polarity of the drivers. You’ll need to connect the following wires:
- Positive wire: The positive wire connects the positive terminal of the driver to the crossover.
- Negative wire: The negative wire connects the negative terminal of the driver to the crossover.
