Walking into Jaç Hi-Fi Café in Barcelona’s Avinguda Diagonal feels like stumbling onto something special. This isn’t your typical coffee shop with music playing in the background. Here, the music is the point, and everything else revolves around creating the perfect listening experience.

The concept comes from Japan’s jazz kissa bars, where people go specifically to listen to music on high-end sound systems. Designer Isern Serra took that idea and gave it a Barcelona twist. The name “Jaç” works on multiple levels – it references jazz, nods to Japanese listening culture, and means “to recline, rest, and let go” in Catalan.

What immediately catches your attention is how different this place looks. The bar itself is actually a giant speaker cabinet made from walnut wood. It’s functional furniture and high-end audio equipment rolled into one. You won’t find speakers awkwardly mounted on walls here. Instead, custom Bloom Island speakers are built right into the furniture, so the sound feels like it’s coming from the room itself.

The materials feel warm and deliberate. Rich walnut wood covers most surfaces, contrasted with smooth beige microcement walls. Everything has this golden, honey-colored glow that makes you want to settle in for hours. The curved seating area in back is particularly clever – walnut-clad walls flow up into an arched ceiling, creating this intimate listening nook where you can actually focus on the music.

Serra clearly studied how Japanese jazz kissa works. These bars emerged in 1960s Tokyo as places where music lovers could experience incredible sound quality in a respectful, quiet atmosphere. But instead of copying that aesthetic exactly, he made it feel distinctly Catalan. There’s still that social, café-going culture Barcelona is known for, just with better attention to what you’re actually hearing.

The lighting helps set the mood, too. Midcentury fixtures create different zones throughout the space, so you naturally move from the more social bar area to quieter listening spots. It all feels intentional without being pushy about it. What’s refreshing is how seriously they take the audio experience. In most cafés, music is just atmospheric – something to fill the silence. Here, they’ve designed every surface and angle with acoustics in mind. The result is a sound that feels clean and present without being overwhelming.

This kind of place feels particularly relevant right now. We’re constantly surrounded by noise and distractions, so having a space dedicated to actually listening to music feels almost radical. It’s not trying to be everything to everyone – just really good at this one specific thing.

Jaç manages to honor both traditions without feeling like cultural tourism. It’s genuinely Barcelona meeting Tokyo, creating something that couldn’t exist anywhere else. Whether this signals some broader trend toward more experiential dining and drinking spaces remains to be seen. For now, it’s just a really thoughtful place to drink coffee and remember why you fell in love with certain songs in the first place.

Norton and McAfee are among the original AV vendors. Does one have an edge over the other?

The LEGO Technic 8810 Café Racer traces its roots back to the early 90s when it was first released. The 80-piece set was a childhood buddy for kids of all ages and even adults into LEGO brick building on leisurely weekends. Also known as the Technic Alpha Racer, the model gains an average 3% yearly rise in value.

Going by its collectible worth, the LEGO café racer is a valid inspiration for animatronics creator Matt Denton who has developed a rideable LEGO Technic 8810 café racer made from 3D printed parts to preserve the attachable and detachable essence of the LEGO brick influence. Each of the individual parts is created from PolyLite and polycarbonate materials to emulate the snappable plastic blocks.

Designer: Matt Denton

Matt is known for his creations culminating from exposure to the engineering and design domain. The Star Wars BB-8 is one of them. Now the 33-year-old crafter has brought the LEGO café racer into a functional electric bike which is a monkey bike in its DNA. The two-wheeler can take the weight of an adult and like all monkey bikes is a handful when it comes to steering in tight spaces at low speeds. The specialist in Animatronics Control Systems had a different kind of challenge at hand in building this ride. So, he decided to use an e-bike kit that had a motor controller, screen, disc brakes, tires, and brake levers. Putting together the custom-built parts that resemble a LEGO brick and the kit’s components required more than a snap of two individual parts since the thing produced vibrations from the movement and engine noise.

To maintain visual aesthetics, Matt only used parts from the kit that were needed without breaking the LEGO-themed look. The 3D-printed handlebar and the position of the front wheel is determined to then move on to the headlights section. Then only he went on to finalize the frame and thereafter the foot pegs, suspension, axle and wiring were done. The final components on this LEGO monkey bike were the forks, seat, battery, water bottle and a bottle holder frame.

The only thing he then tests is the rideability and the ability to reverse. After making the final adjustments to the power, steering and brake balance, the LEGO Technic café racer is ready for the streets.
