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.

WIDE Dress Shoes With SUPPORT
Size: 10.5, Color: Brown
I've seen dress shoes and worn dress shoes before, but these are simply the best dress shoes I've ever worn my entire life. 99% of dress shoes have the same problem, they have the thinnest little soles that offer no support. BRUNO MARC HAS SOLVED THE PROBLEM. These dress shoes not only support wide feet like mine who historically have had and still have little support in the market, but Bruno Marc has wide options that fit perfectly, and the support with the thick foam sole is so needed and awesome. I had a pleasant surprise putting these things on and there being some tactile grip enhancers inside the shoe so you can feel the shoes better and get a little tickle / massage while you're at it. These things are dripping with style, easy to wear, and while they might look firm on the outside, on the inside the shoe just has such a nice flexibility and foamy feel, the top where the top of your feet feel the roof of the shoe, it has such perfect ooey gooey support I can't believe it. The outside sole also has this neat tactile feel. The durability looks good and feels good for now.

Perfect Blend of Comfort and Style
Size: 9, Color: Brown, Size: 9, Color: Brown
I recently purchased size 9 of these shoes, and they exceeded my expectations in every way! Here’s what I love about them: 1. Comfort: The moment I put them on, I noticed how soft and supportive they felt. The cushioning provides all-day comfort, making them perfect for long walks, workdays, or running errands. 2. Fit: The sizing is spot-on! I ordered my usual size, and they fit perfectly with no need to size up or down. There’s enough room for my toes to move without feeling too loose or tight. 3. Style: These shoes look even better in person. The design is sleek and versatile, making them easy to pair with both casual and semi-formal outfits. I’ve received several compliments already! 4. Durability: I put it on the day of purchase. After wearing them daily for a couple of days, they still look brand new. The stitching and material seem high-quality and built to last. 5. Value for Money: For the price, these shoes deliver exceptional value. You’re getting premium comfort and style without breaking the bank. Final Thoughts: If you’re looking for shoes that offer comfort, style, and durability, I highly recommend giving these a try. I’ll definitely be considering another pair in a different color soon! To conclude, I’m very happy for this purchase. Will definitely buy again.

Comfortable, Easy to Clean, and Held Up at Coachella
Size: 12, Color: White, Size: 12, Color: White
I’m really happy with this purchase. The shoes are very comfortable, and the product description is accurate. I followed the sizing recommendation based on my foot type and went one size up—they fit perfectly. I bought these for Coachella, and they definitely held up. I was on my feet all day, and they stayed comfortable the entire time. What impressed me most is how easy they were to keep clean. At the end of each day, I was able to wipe them down and maintain their whiteness without much effort. Once I got home, I gave them a deeper clean, and they honestly looked as good as new. Even the laces cleaned up easily. Now I’ve transitioned them into my regular work shoes, and they still look great. Overall, I’m very satisfied with this purchase and would definitely recommend them.

Great shoes that are well made, lite weight, and comfortable.
Size: 12, Color: Brown
Just received my 2nd pair of shoes from Bruno Marc in a size 12. These are really lite and comfortable. It can be dressed down to be a casual shoe or dressed up with a nice suit. These run true to size so I ordered my usual size 12 and the fit was perfect. Being my 2nd pair of Bruno Marc's, I like the quality of their shoes and each shoe is described appropriately on fit and comfort. Insole of these shoes were awesome and provided soft comfort on the feet along with a slight arch support too. Will definitely consider ordering more Bruno Marc shoes in the future.
