Product Information
Full details
The In Phase BX28S is designed for car audio enthusiasts who want to upgrade their vehicle's low-end frequency response without sacrificing significant trunk space. This pre-loaded, dual 8-inch sealed enclosure delivers tight, accurate, and distortion-free bass that enhances a variety of music genres. While it offers excellent sonic precision and a space-saving footprint, users should be aware that the sealed cabinet design prioritizes musical accuracy over the extreme, earth-shaking volume levels typically associated with ported "bass reflex" boxes.

FAQs
Does the BX28S come with an amplifier?
No, the BX28S is a passive subwoofer enclosure and requires an external car audio amplifier to function.
Can I replace the speakers inside the box?
The enclosure is designed specifically for the included drivers. Replacing them may alter the enclosure's performance characteristics.
What is the benefit of a sealed enclosure over a ported one?
Sealed enclosures typically provide tighter, more accurate bass and a smoother response, whereas ported enclosures are generally louder but less precise.
Is this enclosure suitable for all music types?
Yes, but it performs best for listeners who prioritize musicality, clarity, and tight response over maximum volume.
What kind of wood is used?
The enclosure is constructed from 18mm sustainably sourced wood, chosen for its density and ability to minimize cabinet vibration.
Troubleshooting
Weak bass response
Check your amplifier's low-pass filter (LPF) settings and ensure the wiring is not reversed (out of phase).
Distortion at high volumes
Reduce the gain on your amplifier or ensure the source audio is not clipping.
Rattling sounds from the enclosure
Ensure all mounting screws are tight and that the enclosure is firmly secured to the vehicle chassis.
Pros and Cons
Pros
- High-accuracy, distortion-free sound reproduction
- Space-saving design ideal for smaller vehicles
- Solid 18mm wood build reduces enclosure resonance
- Convenient pre-loaded setup saves installation time
- Consistent bass performance across various music types
Cons
- Lower peak sound pressure level compared to ported enclosures
- Requires a compatible amplifier to drive dual subwoofers
- Fixed physical dimensions may not fit all vehicle storage areas
Setup, Compatibility & Care
To ensure peak performance, verify that your amplifier is rated to handle the power requirements of the dual subwoofer setup at the 4-ohm load.
- Placement: Position the enclosure on a flat, stable surface in your trunk or cargo area. Use mounting brackets (not included) if necessary to prevent sliding during driving.
- Wiring: Use high-quality speaker wire connected to the terminal cup on the rear of the unit. Ensure the positive and negative terminals are matched correctly with your amplifier output.
- Care: Keep the subwoofer cones free of debris. To clean the exterior carpet, use a soft-bristled brush or a vacuum attachment. Avoid exposing the enclosure to moisture, as the wood construction can be damaged by prolonged water contact.
