8″ Glass-Aramid Composite Woofer: The KRK S8.4 features an 8-inch glass-aramid composite woofer that delivers tight, defined bass, essential for precise audio production. This custom-voiced woofer provides accurate low-end frequencies, crucial for professional mixing and mastering.

Class-D Power Amplifier: Powered by a Class-D amplifier, the subwoofer offers enhanced transient response, giving you greater control, punch, and clarity. The efficient amplifier ensures even the lowest frequencies are well-articulated, making your mixes more impactful.

Four-Position Selectable Crossover: The S8.4 subwoofer integrates seamlessly with a variety of studio monitors. Its four-position selectable crossover allows you to adjust frequency management according to your existing setup, ensuring perfect balance and integration of low-end frequencies.

Bypass Control with Optional Footswitch: For increased workflow flexibility, the S8.4 includes an exclusive bypass-control feature. With an optional footswitch, you can quickly switch between full-range and subwoofer modes, routing audio directly to the monitors without disrupting your session.

Front-Firing Port Design: The front-firing port design extends low frequencies while minimizing turbulence and boundary coupling. This design ensures cleaner and more precise bass reproduction, improving the overall sound quality in your studio environment.

Durable MDF Enclosure: The S8.4 is built with a reinforced MDF enclosure, ensuring maximum durability and longevity. This rugged construction helps maintain the subwoofer’s superior sound quality even in challenging studio conditions.

Compact Design: Despite its powerful output, the S8.4 maintains a compact form factor, making it ideal for studios with limited space. Its small size does not compromise its professional-grade performance, delivering powerful low-end reproduction.

Delivery Exclusions

PLEASE NOTE:

Some products are exceptionally large, heavy or bulky and require specialist freight services. This typically includes items such as large PA speakers, dual 15″ speaker cabinets, dual 18″ subwoofers, flight cases and other oversized or very heavy equipment.

We work hard to keep our prices as competitive as possible and, in most cases, delivery is completely covered by our standard shipping rates. However, for certain oversized items being delivered to regional or outlying areas, the actual courier cost can be significantly higher than standard deliveries. This is also owing to factors completely outside of our control (petrol costs and rising costs of delivery by courier partners)

If this applies to your order, we will always contact you before dispatch to discuss the available options. These may include:

Proceeding with a small additional freight contribution.
Collecting the order from one of our suppliers or a nearby courier depot where available.
Cancelling the order for a full refund if a suitable solution cannot be reached.

Please be assured that we only request an additional freight contribution in exceptional circumstances where the courier cost is substantially higher than normal. Our goal is always to deliver your order at the advertised price whenever possible.

If you’re unsure whether an item may be affected, you’re welcome to contact us before placing your order and we’ll gladly provide a delivery estimate.

Thank you for your understanding and ongoing support!
