Built specifically for highly demanding applications, SUB 8003-AS MK3 is the perfect workhorse for music professionals.

Legendary subwoofers
RCF subwoofers are the first choice of many sound engineers, thanks to the very high SPL levels at very low frequencies, small dimensions compared to the competitors, self-powered design, internal delay control, long-term reliability, cardioid configuration options, and impressive size/weight to SPL output ratio. Your crowd will be able to live an engaging immersive experience in both live sound or DJing applications.

Industry-Leading Subs
Lightweight and powerful, RCF woofers are a reference in high performance. RCF Precision Transducers engineers have developed new specific magnet sizes and molds to optimize magnetic flux while maintaining a low weight. The 18", 4.0" voice coil magnetic circuit topology is capable of delivering the highest, balanced level of performance in three specific areas: maintenance of a consistent, high integrity magnetic flux gap, exceptionally low distortion and efficiently integrating the magnetic circuit in a minimum weight design. The T-pole design optimization generates the minimum amount of flux modulation in the magnetic assembly during typical voice coil movement within the gap.

Power that moves
The most powerful amplifier in its class. RCF's improvements in transducer design make our woofers stronger and powerful, so the amplifier follows the evolution. With 2200W power, our Class-D amplifier is able to manage extreme sound pressure levels with an ultra-fast attack, realistic transient response, and very low heat loss. So energy-efficient that there's no need for a cooling fan - the amplifier is attached to a solid aluminum heat exchanger in the rear of the cabinet - with no moving parts. The stereo input circuit with crossover features a new low distortion design with an advanced safety limiter, maintaining the true character of the input signal at all levels. RCF amplifiers are designed according to EN62368-1 for maximum safety and present a Switch Mode Power Supply section joining high-efficiency with minimum weight.

Tour-Ready Workhorse
The RCF cabinets are made of high-quality multi-ply hardwood coated with a black polyurea finish. The subs are stackable and light-weight, for easy set-up and tear down, thanks to the ergonomic handles. A pole receptacle on top and side allows the use of the box in various configurations. The powder-coated front grille integrates a special transparent-to-sound foam backing on the inside to further protect the transducers from dust.

Puppy's favourite, but not built to last.
My puppy absolutely adores this tug-of-war ball! However, I have to mention the durability—it started fraying after just a few days of use. While it’s still usable, the material doesn’t hold up well to enthusiastic chewing and tugging. If your pup is a strong chewer, this might not last long. That said, for the price and the joy it brings my puppy, I’d still consider buying it again—just with the expectation that it’s more of a short-term toy. Great for light play, but not built for heavy-duty tug sessions.
