Yes. You can use subwoofers with different driver sizes together, but diameter alone does not determine whether they will work well as a pair. Their frequency response, phase behavior, output capability, placement and your receiver’s controls all affect how their sound combines. Expect to spend more time positioning and calibrating a mismatched pair than a pair of similar models.
What determines whether different subwoofers work together?
Frequency response and phase
Two subs can reinforce each other at some frequencies and partially cancel at others. Different low-frequency cutoffs and phase behavior are among the reasons. As Audioholics explains in its multi-subwoofer connection guide, mixing brands and types is possible, but it takes more care; identical or similarly capable subs are generally easier to integrate.

Enclosure design
Sealed and ported subwoofers can have different phase responses. SVS warns that the difference can be particularly relevant near a ported sub’s tuning frequency, where cancellation may reduce output. The company recommends matching enclosure types. This is manufacturer guidance, not proof that every sealed-and-ported pairing will perform poorly: the result depends on the specific subs, settings and room. See SVS’s discussion of mixing ported and sealed subwoofers.

Output capability
A much less capable sub can limit the practical dynamic range and bandwidth of the overall setup. Both units should be suited to the room and listening demands, rather than relying on the larger driver to compensate for a weaker model. Audioholics discusses this limitation in its connection guide.

- Line level LFE RCA inputs for maximum receiver compatibility
- Dimensions 14 5" x 12 5" x 16 4"
Compare the subs before connecting them
Driver diameter is only one specification to consider. Compare the characteristics that affect integration and whether your equipment can adjust for them.
| What to compare | Why it matters |
|---|---|
| Enclosure type | Sealed and ported designs can behave differently in phase, especially near a ported model’s tuning frequency. |
| Low-frequency response and roll-off | Different response limits can make the subs contribute unevenly across the bass range. |
| Output capability | A less capable sub may constrain the system’s usable output or bandwidth. |
| Phase, delay and EQ controls | These controls can help align the subs, if the subs or receiver provide them. |
| Receiver support | Available outputs, calibration and supported layouts vary by receiver model. |
| Placement and listening area | Room position affects the combined response, and settings that suit one seat may not suit others. |
These comparisons follow the setup factors covered by Audioholics’ multiple-subwoofer setup guide and the enclosure guidance from SVS. Similarity across these factors usually means less integration work; matching driver diameter by itself is not a compatibility rule.

How to set up a mismatched pair
- Check your receiver’s capabilities. Confirm it has the outputs and calibration controls required for your number of subs. If the receiver offers multiple-sub layouts, use the manual for your exact model. For example, the Denon AVR-X3800H manual documents supported symmetrical left/right, front/rear and four-corner arrangements; do not assume another receiver offers the same options.
- Set up the signal path. Use a shared bass signal. Configure each sub’s internal low-pass filter so it does not conflict with the receiver’s bass management; follow the instructions for your equipment.
- Try practical placements. Test feasible positions and assess how the combined response behaves at the main listening positions. Placement is a core variable in Audioholics’ setup and calibration guidance.
- Start from sensible defaults. Begin with levels reasonably matched and phase controls at their defaults unless the manuals say otherwise. Then make repeatable checks while adjusting level, distance or delay, phase, crossover and placement as the equipment allows.
- Run calibration after placement. Room correction can help but cannot make every combination or location optimal. SVS specifically instructs users of its Auto EQ to run it on each SVS sub individually before receiver calibration; check SVS’s Auto EQ FAQ and your own product instructions rather than applying that sequence to other brands.
- Check more than one seat. If several people use the system, reassess the response at their listening positions. A setting that works best at one seat may not be best across the room.
An SPL meter is optional. Audioholics describes using one with a rumble tone when aligning subs, but it is only an aid for level checks and does not measure full-room frequency response by itself.
When is matching models the better choice?
Matching models, or choosing subs with similar designs and output capability, is the easier path when you want simpler integration or when your receiver offers limited independent adjustment. A mismatched pair can still work, but it may take more placement and calibration effort, and the result depends on the combined response rather than the cabinet labels. For additional context on the potential role of a second sub, see SVS’s overview of dual subwoofers.
