Overview
A big driver in a deep cabinet reinforces low frequencies from a receiver over an RCA cable, with the listing naming a tabletop mount rather than a floor stand.
Klipsch gives the SPL-120 a strong power rating and a plain RCA input, which suits receivers with a subwoofer output. The tabletop mounting entry is odd for the weight, and the listing gives no frequency range.
Who it's for
Rooms with a stable surface or open floor near the front speakers suit this sub. Small apartments and anyone who needs a wireless link should consider a smaller sub.
Pros and cons
- Large driver for low frequencies
- High listed power figure
- Tabletop mount entry is unclear
- Frequency range not listed
- Heavy and bulky
Performance notes
Low-frequency output depends on driver size, amplifier power and cabinet volume, and the room shapes the result. Corner placement boosts level while open space thins it. A heavy cabinet resists vibration, but needs a surface that can bear the load.
