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.

Good stand but has issues.
Color: Black - Sunburst
Very sturdy and looks good. But, the part that holds the umbrella is loose and requires a wedge to stop it spinning (I used a plastic knife). Also the screw on the bottom RUSTS and in a BIG way. To solve the rust issue I put an old plastic cutting board under it. We use it with the modifications mentioned.

Soft, cool, good size

This bed is pretty nice! The cool sides really stays cool all day. My cat is still getting used to it but I think it’s a great addition for summer. It also seems like you can just put it in the washer to clean it.

Good product.
Color: Gray, Size: 18"x24"
I live in Michigan so we have cool nights. We have hot days. Last night I went to pick up my new cooling mat to put it up for the evening and was totally blown away at how cool it was to the touch. For the price, the quality is outstanding. I will be purchasing more in the future once I know that my cats will use it. We haven't got that far yet, but once they do I will try to include pictures of them using it. I hope this helps someone as I am pretty picky about what product I buy. I was thoroughly impressed. The back side, or the warmer side is very soft and perfect for winter time use. It was an absolute genius idea to make one that is universal.

Max loves it!
Color: Gray, Size: 24"x36"
Phoenix got hotter sooner this year, and even with a short haircut, my baby kept trying to find a cooler spot. I had my doubts about whether this bed would actually keep him cooler, and Max was initially suspicious (especially after he saw the cat picture on the label). It only took one hot afternoon to sell him on this cool, comfortable lounge spot. It does feel cooler; it's a lot more comfortable than the hard tile floor and he is out of the way when on it. Good buy at a good price.
