SUB 808-AS is a compact low-profile high-performance active subwoofer. It features two vented-loaded 8” cone woofers powered by a 2000 Watts two-channel amplifier -one for each woofer- on a baltic birch plywood cabinet painted with black or white polyurea and weatherproof treatment. Management and tuning are available via RDNet software. The cabinet features rubber feet on two sides and two threaded pole-mounts for horizontal and vertical placement. Two stabilizing brackets make the vertical placement stable and firm. SUB 808-AS can be used stand-alone, in subwoofer arrays, or as the low-frequency complement for KX 515-A speaker.
Advanced electronics
The high-powered Class-D amplifiers, tailored for each transducer, deploy pristine sound with efficient heat dissipation at the lowest possible distortion, along with low power consumption.
High-end AD/DA conversion up to 96 kHz - 32-bit floating-point, and onboard DSP for the best sound quality. Thanks to the proprietary RDNet networked management and control, every KX speaker provides in-depth remote monitoring through multiple sensors. The system engineer has immediate feedback of transducer status, fan speed, temperature, VU meters, limiters and much more.

Legendary woofers
RCF subwoofers are the first choice of many sound engineers, thanks to the very high SPL levels at very low frequencies, smaller dimensions compared to others in its category. Self-powered design, RDNet remote control, easy configuration of subwoofer arrays (i.e. cardioid subs), and impressive size/weight to SPL output ratio create an engaging, immersive experience for any audience.
Built for everyday use
Use it as a compact and powerful main system or to supplement a larger system. The waterproof cabinet is built in high-strength baltic birch plywood coated with black, robust, and scratch-resistant polyurea paint. Attached to a solid machined aluminum structure at the back, the amplifier heat dissipation is efficient and the cabinet is sturdy and stiff. A strong powder-coated metal grille protects the front, and an acoustically transparent
Rig it anywhere
The only limit is your imagination. With multiple rigging accessories and the unobtrusive form factor of the cabinet, KX 515-A is suitable for a wide range of configurations including hanging, pole-, truss-, wall- or ceiling-mounting— at any angle in horizontal or vertical orientation. The rotatable waveguide (and rotatable logo) allows for perfect dispersion control at any position.
The speaker’s rigging is fast and easy using the practical Quick Fit socket to easily install accessories such as the clamp mount, pole mount, horizontal brackets, or using the two M10 threads on top and bottom of the cabinet. You will always find a place for KX 515-A.

Tour Ready Construction
Attached to a solid machined aluminum structure on the rear panel, the amplifier ensures efficient heat dissipation. The enclosure is internally reinforced and sturdy, equipped with waterproof powerCON® TRUE1 TOP mains connectors, guaranteeing durability under any outdoor conditions.
Bass Motion Control
When searching for an extended bass with enhanced performance, RCF engineers found a way to remove the high-pass filter, replacing it with a forward-thinking approach. Introducing BMC (Bass Motion Control), the newly advanced woofer excursion management feature. The speaker equipped with BMC can handle the lowest audible frequencies without affecting the woofer stability, with extended linearity and better sound integrity.
The BMC method works by creating a complete map of the dynamic behavior of the woofer, to generate a custom algorithm that only limits over-excursions. This gives total freedom of signal reproduction to the transducer. When high-pass filters normally protect the woofer motion from becoming destructive but change the phase behavior, the new BMC algorithm breaks conventional rules.

Beautiful end table that works well anywhere.
Color: Black, Number of Items: 1
The JUSTOGO end table immediately stands out thanks to its unique, modern design and practical features. Its rectangular shape makes it surprisingly versatile. You can position it to showcase the three open shelves for easy access and display, or use it as a narrower separation piece or traditional end table. That flexibility makes it adaptable to different rooms and layouts.
One of the most thoughtful design choices is the placement of the built-in USB ports and power outlets. Located on the middle shelf, they don’t crowd the tabletop and still remain easily accessible for charging devices. This keeps the top surface clean and fully usable while ensuring cords aren’t stretched too far.
The black finish is another plus. It’s neutral, clean-looking, and blends easily with a wide range of décor styles.
If there’s a downside, it’s the assembly process. The instructions could be clearer, and while the advertised setup time is 20 minutes, it realistically takes closer to 40. That said, assembly is a one-time task, and once it’s complete, you’re left with a sturdy, functional, and visually appealing piece of furniture. Overall, it’s a smart combination of style and utility.

Pretty good so far
Color: White, Size: 6FT (2U1C)
Perfect small size for what I was looking for, I wanted one for my standing desk (and in white for a cleaner look) that didn't take up too much space but still offered all the ports I was looking for. The clamp works great, easy to install, I like that on top it has two tiny lights to indicate that it's on and working well. Mainly I really appreciate that it came with one of those white velcro cable wrap so I can properly wrap the excess length :)

Love the small size and desk mount bracket.
Color: Black, Size: 6FT (2U1C)
Great quality and perfect size to get rid of those old bulky switches for the desk. Saves a lot of desk space for the newer smaller platform computers. Having extra charging sockets build it also frees up plug space.

Great surge protector, huge space saver!
Color: Black, Size: 6FT (2U1C)
This surge protector is fantastic! It’s compact but still has enough room to house several large bulky adapter sized plugs without blocking access to the other outlets or ports. Clamp holds nice and tightly and it takes up much less room than a traditional power strip. It’s perfect.
