KRK S10.4 Studio Subwoofer
The KRK S10G4 is an active 10" studio subwoofer engineered to extend the low-end response of near-field monitors in project and home studios. A 160 W Class D amplifier drives a custom glass-aramid composite woofer down to 27 Hz, while the four-position crossover and footswitch-controlled bypass let engineers A/B the sub in and out of the signal chain during mix decisions.
- 10" glass-aramid composite woofer paired with a 160 W Class D amplifier for tight, controlled low end
- Four-position crossover (60/70/80/90 Hz) with matching high-pass filter on the monitor outputs
- Front-firing bass-reflex port in a reinforced MDF enclosure reduces boundary coupling near walls
- Universal I/O: balanced XLR, 6.3 mm TRS, unbalanced RCA, plus a footswitch input for hands-free bypass
KRK S10G4 — Active Studio Subwoofer for Extended Low End
The KRK S10G4 is an active studio subwoofer extending the low end of near-field monitoring setups. A 10" glass-aramid woofer and 160 W Class D amplifier deliver a maximum SPL of 117 dB with bass extension to 27 Hz. The reinforced MDF cabinet and front-firing port keep the cabinet stable. This model suits engineers working on electronic, hip-hop, and film-scoring projects.
What Sets This Sub Apart in Its Category
Unlike many entry-level subs, this unit includes a four-position crossover (60, 70, 80, 90 Hz) with a matching high-pass filter on the monitor outputs, preventing overlap and phase cancellation. The optional footswitch bypass routes full-range audio back to the monitors.
Driver and Amplification — Headroom and Control
The Class D amplifier keeps the cabinet light and cool while delivering the transient response needed for kick drums and sub-bass layers. The glass-aramid cone balances stiffness and damping so transients stay defined.
- LF Driver: 10" glass-aramid composite woofer — stiff, low-distortion cone for tight transients
- Amplifier Power: 160 W Class D — high headroom, low thermal load
- Max SPL: 117 dB — enough output for near-field and small-room monitoring
Frequency Range and Crossover — Tuning to Your Monitors
The crossover is the key integration point between sub and satellites. Polarity inversion, input sensitivity, and ground-lift switches dial out phase and hum problems.
- Frequency Range: 27 Hz – 156 Hz — extends below typical near-field monitor response
- Crossover: 60 / 70 / 80 / 90 Hz selectable — matches common 5"–8" monitor low-end limits
- HPF Bypass: via optional footswitch — instant A/B between full-range and sub-filtered monitoring
Connectivity and Physical Integration
Universal I/O lets the sub slot into almost any existing rig without adapter cables. The reinforced MDF enclosure and universal-voltage power supply make installation straightforward.
- Inputs: Balanced XLR, 6.3 mm TRS, RCA, footswitch — covers pro and consumer gear
- Outputs: XLR, 6.3 mm TRS, RCA — pass-through to monitors
- Dimensions: 341 × 479 × 310 mm, Weight: 15.88 kg — fits under most desks
