Our Super Slim in-wall range flagship, the WSS430 effortlessly delivers the most critical audiophile and cinema experiences. Using design principles and technology from our flagship Platinum II speaker models, performance from this formidable in-wall challenges that from the best high-end, box speaker designs.

The WSS430 flagship maintains its siblings’ shallow depth – all three feature identical footprints – and offers supreme audio performance, drawing on design principles, and materials, from Monitor’s Audio’s high-end Platinum II speakers.

The WSS430 range topper employs dished C-CAM cones to ensure ultimate diaphragm rigidity – the main aim here is to reduce distortion. High strength Neo magnets and larger voice coils provide incredible driving force, low magnetic leakage, and slim profile. The magnetic system provides an ‘under-hung’ motor arrangement, ensuring the coil stays in the gap, reducing distortion further and increasing power handling.

Still just 50 mm deep, there is a lot going on with the WSS430. The MPD high frequency transducer technology – also from Monitor Audio’s flagship Platinum II designs – ensures incredibly low distortion, delivering clear high frequency to over 50 kHz. Remove the model’s magnetic front trim and you can rotate the tweeter to provide the optimum dispersion when using the model in landscape orientation.

Solid Kids Sandals, Overpriced Like Most Kids Shoes 🌞
Size: 11 Little Kid, Color: Brown, Size: 11 Little Kid, Color: Brown
My son hasn’t worn these yet since it’s December in Indiana and sandals + snow obviously don’t mix. 😂 So this review is based on first impressions rather than long term wear. That said, these seem wider than a lot of typical kids’ sandals, which I REALLY appreciate since we tend to have wider feet in our family. #hobbitfeet The quality feels pretty decent overall. They’re described as lightweight, and while they’re not insanely lightweight, they do have enough weight to feel semi-sturdy and not flimsy or cheap. I like the style and color, and I think they’ll work well for my son once warmer weather hits. My main complaint is the price. At just under $24 at the time of this review, it feels a little high for kids’ sandals and for what these are. I really feel like $20 MAX would make more sense. Kids shoes are almost always priced like adult shoes, even though they clearly use less material, and that’s hard for me to understand and wrap my mind around. Overall, these seem solid for daily wear, I just wish the price was a bit more reasonable and affordable.

Great basic and timeless design
Size: 12 Little Kid, Color: Brown
These sandals are a great find! They’re super easy to get on and off thanks to the Velcro straps, which is a huge win for little ones learning to be more independent. The fit is adjustable and secure, so they stay in place well during all kinds of play. The cork-style footbed is comfortable and gives good support, and the overall design feels sturdy enough to handle everyday wear. They’re lightweight but still durable, and have held up really well so far. They also have a classic, versatile look that goes with just about everything, perfect for summer outfits. Overall, a reliable, comfortable sandal that’s great for active kids. Would definitely buy again!
