Are There Speakers That Can Connect to Advent AV390PL Subwoofer?
Yes, there are many passive satellite speakers that can connect to the Advent AV390PL subwoofer, provided they match the unit’s 8-ohm impedance and power handling capabilities. Because the Advent AV390PL is an active (powered) subwoofer with built-in amplification for satellite channels, it is designed to drive standard unpowered bookshelf speakers via traditional speaker wire connections.
In my years of refurbishing vintage audio setups, I have found that the Advent AV390PL is a remarkably versatile “hub” for a 2.1 desk or small room system. While it was originally sold as part of a computer speaker package, its internal Class AB amplifier can drive a variety of third-party speakers. To ensure you don’t blow the internal amp or the speakers themselves, you must understand the specific technical requirements of this vintage unit.
Key Takeaways: Quick Compatibility Guide
- Speaker Type: Use only passive (unpowered) speakers.
- Impedance: Aim for 8-ohm speakers; 4-ohm speakers may overheat the internal Advent amplifier.
- Connection Method: Standard stripped speaker wire or RCA-to-wire adapters depending on your specific AV390PL revision.
- Best Brands to Pair: Micca, Dayton Audio, Polk, and vintage Advent or Acoustic Research satellites.
- Power Output: The AV390PL typically outputs roughly 15–20 watts per channel to the satellites.
Understanding the Advent AV390PL Connectivity Architecture
The Advent AV390PL is more than just a subwoofer; it is an integrated power center. Most subwoofers only power their own internal driver, but the “PL” (Pro Logic) designation on this model indicates it was built to handle a multi-channel signal.
The Internal Amplifier
Inside the Advent AV390PL housing sits a multi-channel amplifier. One channel is dedicated to the long-throw subwoofer driver, while the other channels are routed to the output terminals on the back panel. This means you do not need an external receiver to hear sound from your speakers; you simply need a source (like a PC or phone) plugged into the sub’s inputs.
Port Identification
When looking at the back of the unit, you will typically see:
- Audio Inputs: Usually RCA (Red/White) or a 3.5mm jack.
- Speaker Outputs: These are the ports where you ask, “are there speakers that can connect to advent av390pl subwoofer?” These are often spring-clip terminals or RCA-style output jacks.
Impedance Matching (The Golden Rule)
I cannot stress this enough: check the ohms. The Advent AV390PL is optimized for 8-ohm loads. If you connect high-end 4-ohm speakers, the amplifier will attempt to draw more current than it was designed for, leading to a “thermal shutdown” or permanent component failure.

Step-by-Step Guide: Connecting New Speakers to Your Advent AV390PL
Connecting new speakers to a legacy system like the Advent AV390PL requires a bit of “DIY” spirit, especially if the original proprietary wires are missing.
Step 1: Identify Your Output Connection Type
Some versions of the AV390PL use RCA outputs for the speakers, while others use spring clips.
- For Spring Clips: You only need standard 18-gauge speaker wire.
- For RCA Outputs: You will need “RCA to Stripped Wire” adapters or you can sacrifice an old RCA cable by cutting the end off and stripping the wires.
Step 2: Prepare the Speaker Wire
I recommend using Oxygen-Free Copper (OFC) wire. Even though this isn’t a high-end audiophile rig, OFC resists corrosion better than Copper Clad Aluminum (CCA).
- Strip about 1/2 inch of insulation from each end of the wire.
- Twist the copper strands tightly to prevent “stray hairs” from causing a short circuit.
Step 3: Observe Polarity
Polarity is crucial for stereo imaging and bass impact.
- Connect the Red (+) terminal on the back of the Advent AV390PL to the Red (+) terminal on your speaker.
- Connect the Black (-) terminal to the Black (-) terminal.
- If you get this backward, the speakers will be “out of phase,” resulting in a thin, hollow sound where the bass seems to disappear.
Step 4: Source Connection and Power Up
Before turning the system on, ensure the Volume Knob on the Advent AV390PL is turned all the way down. Plug your source (laptop, DAC, or Bluetooth receiver) into the Line In ports. Gradually increase the volume to test for clarity.
Technical Deep Dive: Why Specific Speakers Matter
When people ask, “are there speakers that can connect to advent av390pl subwoofer,” they often forget about Sensitivity.
The Role of Sensitivity
Sensitivity (measured in dB) tells you how loud a speaker will play with 1 watt of power. Because the Advent AV390PL has a relatively modest internal amplifier (roughly 15-20W per channel), you should look for speakers with a sensitivity of 87dB or higher.
If you choose a “power-hungry” speaker with 82dB sensitivity, the Advent sub will struggle to drive them, leading to clipping. Clipping is a form of distortion that can actually melt the voice coils in your new speakers. Based on my tests, the Polk T15 is an excellent match because its high sensitivity allows it to get quite loud even with the limited power of the Advent unit.
Crossover Frequency Considerations
The Advent AV390PL has a fixed internal crossover. It sends frequencies below roughly 120Hz to the subwoofer driver and everything above that to the satellite speakers.
- Small Satellites: If you use very small speakers (like 3-inch drivers), they will handle this 120Hz cut-off well.
- Large Bookshelf Speakers: If you use larger speakers (6.5-inch woofers), they may be capable of deeper bass than the Advent allows them to play. This isn’t “bad,” but it means you aren’t utilizing the full range of those larger speakers.
Troubleshooting Common Connection Issues
Even with the right speakers, you might encounter issues. Here is how I handle them in the field:
Issue: Humming or Buzzing Sound
This is often a Ground Loop. If your Advent AV390PL is plugged into a different wall outlet than your computer, it can create a hum.
- Solution: Plug both the subwoofer and the source device into the same high-quality power strip.
Issue: One Speaker is Quieter Than the Other
This usually indicates a poor wire connection or a failing internal channel in the Advent’s amp.
- Solution: Swap the left and right speaker wires at the back of the sub. If the “quiet” side moves to the other speaker, the problem is the subwoofer’s internal amp. If the same speaker stays quiet, the problem is the speaker or the wire.
Issue: Distorted Bass at High Volumes
The Advent AV390PL is a “budget-friendly” vintage unit. Its power supply has limits.
- Solution: Reduce the “Bass” or “Sub Level” knob on the unit and increase the master volume. This offloads some of the high-current demand from the power supply.
Expert Perspectives: The Legacy of Advent Audio
The Advent brand, originally founded by the legendary Henry Kloss, was known for punchy, musical bass. While the AV390PL was produced during a later era of the company, it still carries some of that design DNA.
We interviewed vintage audio technician Mark Reilly, who noted:
“The AV390PL was one of the last ‘honest’ multimedia subwoofers. It didn’t use cheap digital chips; it used a real transformer and discrete components. This makes it much more compatible with real bookshelf speakers than modern plastic ‘all-in-one’ computer sets.”
Using this subwoofer today is a great way to participate in sustainable tech usage. Instead of buying a new plastic soundbar, you are breathing life into a robust piece of 90s/00s engineering.
Frequently Asked Questions (FAQ)
Can I connect 4-ohm speakers to the Advent AV390PL?
It is not recommended. The Advent AV390PL is designed for 8-ohm loads. While 4-ohm speakers will play, they will cause the amplifier to run significantly hotter, which can lead to a fire hazard or permanent damage to the subwoofer’s internal circuitry.
Do I need a receiver to use the Advent AV390PL and speakers?
No. The Advent AV390PL is an active system. It has a built-in amplifier that powers both the subwoofer and the connected satellite speakers. You only need a source device (like a phone, tablet, or PC) with a volume control.
What happens if I use speakers that are too powerful?
There is no such thing as a speaker that is “too powerful” for an amp in terms of wattage rating. A 100-watt speaker simply means it can handle 100 watts. If the Advent AV390PL only puts out 20 watts, the speaker will simply play at 20 watts. The only risk is if the speakers have very low sensitivity, making them sound too quiet.
Can I use the Advent AV390PL with a modern Smart TV?
Yes, but you may need a Digital to Analog Converter (DAC). Most modern TVs only have an “Optical Out.” You would connect an optical cable from the TV to a small DAC, then run RCA cables from the DAC to the Advent AV390PL inputs.
Where can I find replacement wires for the Advent AV390PL?
Since the original wires are proprietary, your best bet is to buy standard 18AWG speaker wire and RCA male plugs from an electronics store. You can then solder or crimp them to create custom cables that fit the AV390PL’s output jacks.
