Amplifier and Power: The ARTEMIS MAX 18SB features a high-efficiency class D amplifier, delivering 1200W RMS and an impressive 2400W peak power output. This ensures high headroom and consistent, distortion-free performance, even at maximum volume. Ideal for demanding applications, it produces a maximum SPL of 130dB, delivering deep and powerful bass in large venues.

Low-Frequency Driver: Equipped with an 18-inch woofer and a 4-inch voice coil, the subwoofer provides precise and punchy low-end response. Its design ensures optimal cone movement, minimal distortion, and strong sound projection, even under high pressure.

Frequency Range: With a frequency response from 30Hz to 150Hz, the ARTEMIS MAX 18SB captures the full depth of bass content. Whether for live performances or playback, it ensures accurate reproduction of low frequencies across a wide range.

User Controls: Onboard controls allow full customization of output. These include:

Sub Level
Phase switch (0° / 180°)
X-Over Frequency selection (90Hz or 120Hz)
Output Mode (Link / X-Over Outs)

These settings let users fine-tune the subwoofer to match room acoustics or specific system configurations.

Connectivity: The unit features balanced XLR inputs and outputs, allowing clean, professional-grade connections with mixers and other PA components. A VDE power input ensures stable and safe power delivery.

Rugged Cabinet Design: The enclosure is made from 18mm thick plywood with a tough polyurea coating, providing long-term durability. The 1.5mm steel grille offers extra protection without blocking sound dispersion.

Portability and Mounting: Designed for convenience, it includes four recessed handles for easy transport. An M20 threaded pole mount on top allows stacking with full-range speakers. Optional rear-mounted castors make moving the unit effortless during setup and teardown.

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!
