KRK S8-4 Studio Subwoofer
The KRK S8G4 is an 8-inch powered studio subwoofer built to extend the low end of near-field monitors in small to medium-sized control rooms. Driven by a 109 W Class D amplifier and a custom-voiced glass-aramid woofer, this model delivers tight, defined bass with strong transient response and a maximum SPL of 112.8 dB. Universal XLR, TRS, and RCA connectivity plus an optional bypass footswitch make integration with any monitoring chain straightforward, while the four-position crossover lets engineers dial in a clean handoff to their existing monitors.
- 8" glass-aramid composite woofer for accurate, low-distortion bass
- Class D amplifier delivering 109 W continuous power
- A four-position crossover (70/80/90/100 Hz) provides a clean frequency handoff to near-field monitors.
- Front-firing bass-reflex port with reinforced MDF enclosure
KRK S8G4 — 8" Powered Studio Subwoofer for Tight, Defined Low End
This model is an 8-inch powered studio subwoofer designed to extend the low-frequency response of near-field monitors in small to medium-sized control rooms. Built around a custom-voiced glass-aramid composite woofer and a Class D amplifier, the KRK S8G4 delivers tight, defined bass with strong transient response. Project-studio engineers and electronic-music producers often rely on it for accurate sub-bass reproduction.
Glass-Aramid Woofer and Footswitch Bypass
What sets this unit apart is its 8" glass-aramid composite woofer paired with a redesigned front-firing bass-reflex port shaped to reduce port turbulence. The exclusive bypass footswitch control lets the engineer instantly mute the sub and send full-range audio to the monitors without powering down.
Driver and Amplifier Performance
Driver and amplifier pairing determines how cleanly a sub reproduces bass transients and how loudly it can play without distortion.
- LF Driver: 8" glass-aramid composite woofer — stiff, low-mass cone for accurate transient response
- Amplifier: Class D, 109 W continuous — lightweight power with strong transient headroom
- High output levels reaching 112.8 dB provide club-style monitoring performance even in smaller studios.
Frequency Range and Crossover Integration
Crossover settings determine where the cabinet hands off to the near-fields.
- Frequency Range: 29 Hz – 205 Hz — covers the full sub-bass and low-bass spectrum for EDM, hip-hop, and post work
- Native Response: 34.5 Hz – 133 Hz — the subwoofer's own operating window before crossover handoff
- Crossover: four-position selectable (70 / 80 / 90 / 100 Hz) — matches the roll-off of common near-field monitors
Connectivity and Enclosure
Universal I/O ensures the cabinet slots into almost any monitoring chain.
- Inputs / Outputs: XLR L/R, 6.3 mm TRS L/R, RCA L/R — balanced and unbalanced options for studio or hi-fi sources
- Footswitch Input: 6.3 mm jack — engages bypass mode hands-free during mix checks
- The construction features a 15 mm / 18 mm reinforced MDF enclosure measuring 410 × 279 × 292 mm with a total weight of 12 kg.
