Overview
A large living room or dedicated theater with open floor space is where this bigger subwoofer fits, adding low-end output to the main speakers through a wired connection. A down-firing port and an onboard amplifier drive the woofer.
Higher amplifier output and the larger driver are the reason to look at this model, with the same adjustable phase and filter controls for blending. The limits: it needs a wired link to the system, the listing does not say where its controls are, and it takes more floor space.
Who it's for
Larger rooms and surround systems with a clear spot on the floor suit the bigger cabinet, and the adjustment controls help it join the other speakers. Small rooms, desk setups and renters with limited space should look at a smaller sub.
Pros and cons
- Large driver and high amplifier output
- Adjustable phase and low pass filter
- Bass boost feature
- RCA and speaker-level inputs
- Wired connection only
- Subwoofer only, no speakers
- Control layout not described
- Takes a large footprint
Performance notes
A larger woofer moves more air per excursion, which supports deep, higher-level bass in a big room, while the port reinforces the lowest notes. Placement matters: corners and walls add output, and the down-firing port needs space under the cabinet. The low pass filter sets the handoff to the rest of the system and the phase control aligns timing with it.
