Experience Deep Bass and Convenient Control

Get to know them!

The RCF SUB 9016-AS is far beyond a powerful-sounding subwoofer; its built-in DSP and RDNet networked control make it an essential hub for your entire audio system. This subwoofer delivers a robust 4,000 watts through a high-performance 16-inch woofer, producing subterranean bass down to 30Hz with a rafter-shaking 137dB maximum SPL. You’ll welcome the added convenience of the SUB 9016-AS’s digital crossover and factory-tuned speaker presets — plus, with RDTap contactless configuration, you can easily apply your desired settings to each speaker in your system with a simple tap. Additionally, RCF’s innovative Bass Motion Control ensures precise woofer excursion management. Housed in a durable polyurea-coated multi-ply hardwood cabinet, the RCF SUB 9016-AS offers premium low-frequency extension and comprehensive system control in a portable package.

Revolutionize subwoofer setup with RDTap

The SUB 9016-AS brandishes RCF’s revolutionary RDTap feature. RDTap enables contactless setup management and parameter updates, even when the SUB 9016-AS is unpowered. By tapping the RDTap logo on the subwoofer’s back panel with a smartphone running the RDTap app, you can instantly transfer all your setup parameters, including preset configurations, EQ, mid-low compensation for line arrays, and precise delay and time alignment settings to each loudspeaker in your system. RDTap is particularly useful for upgrading your subwoofers and revitalizing older systems with the assistance of presets, EQs, delays, and management via RDNet. Furthermore, unlike long-distance control technologies, RDTap transmits data at close range, ensuring that changes are applied only when intended, without interference from external devices. At Sweetwater, we’ve found that RDTap offers an efficient and user-friendly way to manage subwoofer settings and performance before setup.

The payments equal the amount financed divided by the number of months in the promo period, rounded up to the next whole dollar. These payments may be higher than the payments that would be required if this purchase was a non-promo purchase. During the last month(s) of the promo period the required monthly payment may be reduced due to the prior months’ rounding. Regular account terms apply to non-promo purchases.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
