REL S5 SHO Subwoofer

REL S/5 SHO — Powerful, Fast & Musical Bass

The REL Acoustics S/5 SHO is a serious high-performance subwoofer designed for larger two-channel music systems and home theaters. It combines a 12-inch long-throw driver with a 550-watt Class D amplifier, delivering deep, controlled bass with the speed and articulation REL is known for.

Key Specifications: 12" long-throw driver, 550W RMS Class D amplification, low-frequency extension down to approximately 20 Hz (-6 dB), REL High Level connection, Low Level RCA and LFE inputs, with optional wireless connectivity using REL’s compatible wireless system. Approximate dimensions are 18.2" W × 17.9" H × 20.5" D, with a weight of roughly 69 lbs.

What Room Size Is It Best For?

I would position the S/5 SHO primarily for medium-to-large rooms, approximately 250–600 sq. ft., depending on ceiling height, room construction, listening distance and the desired output level.

For a dedicated two-channel system, a single S/5 SHO can provide excellent extension and scale. For larger rooms, reference-level home cinema, or customers wanting more uniform bass throughout the listening area, a pair can be a significant upgrade.

The S/5 SHO is especially attractive for customers with substantial floorstanding loudspeakers who don't simply want more bass—they want greater foundation, dimensionality, dynamics and realism.

If you’re listing a pre-owned S/5 SHO, I’d also emphasize that this was one of REL’s higher-performance S-Series models and can represent excellent value on the used market.
