ALPINE R Series 8" Subwoofer Box ( Ported ) - SBR-S8D4.2

Award winning SBR-S8D4, named INCAR SUBWOOFER OF THE YEAR – LOADED ENCLOSURE for 2017.

The SBR-S8D4 features Alpine’s Type-R 8″ subwoofer in a custom slot ported enclosure. Ideal for installation in small spaces, its compact size means it can fit virtually anywhere.

The pre-installed subwoofer employs many features typically found in larger models, such as Alpine’s H.A.M.R (High Amplitude Multi Roll) suspension. This unique design allows greater linear excursion while improving control, to achieve maximum output and outstanding sound quality.

Designed to achieve optimal output, the carpeted enclosure features heavy duty MDF construction. Plus, stylish brushed aluminium laminate and a robust grill create the perfect balance of stunning aesthetics and practicality.

Thank you for shopping at Audio Emporium. The following are the terms and conditions that constitute our Shipping Policy.

Where We Ship

We ship to all Australian states and territories, including PO Boxes. We do not currently ship outside Australia.

Shipment Processing

We aim to dispatch orders placed before [CUT-OFF TIME] AEST on a business day the same business day, where stock is on hand. Orders placed after the cut-off, on weekends or on public holidays are dispatched the next business day.

If we are experiencing a high volume of orders or if a product needs to be sourced from our distributor, dispatch may take longer. If there is a significant delay, we will contact you by email or phone.

Orders are not dispatched or delivered on weekends or public holidays.

Shipping Rates and Delivery Estimates

We offer free standard shipping on all orders within Australia to most metropolitan addresses. Bulky or heavy items — such as large subwoofers, multiple amplifiers, or full system shipments — may attract an additional freight surcharge, which will be shown at checkout before you confirm your order. Remote and regional addresses may also attract additional freight depending on the courier.

Estimates are guidelines provided by our courier partners. Delays can occasionally occur and are outside our control.

We can ship to PO Boxes and Australia Post Parcel Lockers, subject to carrier and item size restrictions. Bulky items may not be deliverable to these addresses; if that's the case for your order, we will contact you to arrange an alternative.

Damaged in Transit

If your order arrives damaged, please contact us at [EMAIL] or call [PHONE] within 48 hours of delivery, with photos of the damaged packaging and product.
