Bring your sound to life with the portable, high-power RCF SUB18AX subwoofer.

The SUB 18-AX is a portable 18" high-power active subwoofer for live sound applications with fully featured processing, a color touch panel, and remote control via Bluetooth®. The combination of a latest-generation transducer with a powerful Class-D amplifier delivers sound pressure levels up to 135 dB with exceptional clarity and headroom. SUB AX subwoofers are designed specifically for small to mid-sized venues and ideal for portable applications. SUB 18-AX is the ideal complement for 10", 12" or 15" woofer-size loudspeakers; it centralizes speaker management inside the subwoofer, providing dual crossovers, 8-band EQs, routing, delays, cardioid configurations, and recallable crossover presets. The polyurea-coated all-wood cabinet features a sealed Powercon True1 Top connector.

Advanced Subwoofer with Crossover Presets for RCF Speakers
The key to optimizing your sound system is the precise adjustment of your subwoofer's time alignment. This not only elevates sound quality but also enhances bass response, giving your audience both the beat they can hear and the vibe they can feel.

With internal factory-tuned crossover presets for RCF speakers, your sound system is show-ready in a few easy steps. Simply connect your satellite speakers to the SUB AX, select the crossover preset from the user interface, and you are ready to go. FiRPHASE linear phase is extended to match the subwoofer phase down to the lowest frequencies.

LiveRemote App
Whether you're a musician, DJ, or pro sound engineer, the RCF LiveRemote App, the same app that is used with the ART 9 AX, is now available with the SUB AX models. On the subs, crossover preset selection, system EQ and delay adjustments and crossover individual settings are quickly accessible. When two subwoofer models are paired, they can be set up for 2.2 operation. Available for Android and iOS phones and tablets.

Gig-Ready Solution
RCF cabinets are made of high-quality multi-ply hardwood coated with a rugged black (or white) polyurea finish. Subs are stackable and lightweight, have ergonomic handles with rubber grips, and are designed for easy set-up and tear-down. The M20 threaded pole mount on the top of the cabinet supports RCF speakers of various sizes. The powder-coated front grille integrates a special transparent-to-sound foam backing on the inside to further protect transducers from dust. SUB AX Series subwoofers are built to last, with powerCON® TRUE1 TOP mains connectors, so you can be sure that they will stand up to the rigors of use and transport.

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 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.

Drive the Rhythm of the Beat
With 2,200 Watts of power, our Class-D amplifier can manage extreme sound pressure levels with an ultra-fast attack, realistic transient response, and very low thermal loss. The stereo input circuit features a 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 combining high efficiency with minimum weight.

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.

Decent Comfort, but Honestly Overpriced for the Quality
Color: 06 - Aqua Gray, Size: King (2 Pillowcases)
I’ve heard a lot of hype about the Beckham Hotel Collection, so I decided to treat myself to this king-size set of luxury sateen pillowcases. Out of the box, they look very nice—the sateen weave gives them a subtle, sophisticated sheen that definitely upgrades the look of the bed. They feel relatively soft to the touch, and the 100% cotton material is breathable enough that I didn't find myself flipping the pillow over for a "cool side" in the middle of the night. However, after using them for a bit, I’m struggling to see where the "luxury" price tag comes from. While they are perfectly functional pillowcases, the quality feels fairly mediocre compared to other 500-thread-count sets I’ve owned in the past. The fabric is a bit thinner than I expected, and after just one or two washes, I noticed some slight fraying around the inner seams. They just don't have that heavy, crisp, high-end hotel feel that the marketing leads you to believe you’re getting. The biggest issue for me is the value proposition. There are plenty of other cotton sateen sets available for a fraction of the cost that offer the same—if not better—durability and softness. These aren't bad pillowcases by any means, but they aren't exceptional either. If I’m paying a premium for a "luxury" brand name, I expect the stitching to be flawless and the fabric to feel substantial, but these feel like standard department store linens. I’m giving these three stars because they do the job and look decent on the bed, but they didn't wow me. If you can find them on a deep discount, they might be worth it, but at full price, I feel like I paid more for the branding than the actual quality of the cotton. I'll keep using them for now, but I won't be rushing out to buy a second set anytime soon.

Great Sheets. Just Not what I was looking for
Color: 01 - White, Size: King, Color: 01 - White, Size: King
I purchased pillow cases which are silky thick and somewhat stretcy.. They felt very high quality to me so i wanted the corresponding sheets as well. I purchased sheets from the same manufacturer but they were made from different materials (my fault for not checking that). The sheets i ended up with very nice in their own way. They are King Size, 100% cotton, and look silky, just not what I thought they would be. They are not that thick but fine. The sheets i wanted were a combination of Cotton, Polyester, and some spandex.

Great sheets and value!
Color: 03 - Gray, Size: Queen
Super soft, cool temperature, grey color matches sample. We got the standard queen for our Murphy bed mattress and it fits perfectly! The fitted sheet stays in place with the elasticity of the banding and the thickness is perfect, not too light, not to heavy.
