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.

Excellent!!
Color: Beige, Size: Large
Really loved these shirts for my hubby. They were pretty good quality shirts. Love the linen material. Also love the buttons on the collar which my husband prefers to wear with his jackets. They are very comfortable. As far as size, I ordered according to the size chart. He typically wears a size Large. According to the size chart an XL would best so that’s what I ordered. But I truly believe that a size L would’ve been better. So I would say they are true to size. My husband weighs 205, and has muscles and a size L would’ve been just fine. I ordered 3 because I loved them. I’ll stay with the XL. But if I were to order more I’ll preorder a Large. Very happy with this purchase. They are not slim fit either. Just for an FYI.

Quality + Fit + Value - VERY pleasantly surprised!
Color: Black, Size: Large
I stand at 6.0125" 200lb (showing signs of a Dad bod)., and the large was a perfect fit for me. The quality exceeded expectations, perfect thickness and weight for the colder months. I actually set this up between a Boss & Ted Baker (my-go's to in past 10-years) and asked my date to pick one of three - she grabbed this shirt. if you're looking to re-evaluate how much your spend on dress shirts - this Brand will not disappoint in terms of quality and fit. If your wearing brands like Express, Banana or even worse - Untuck-it, consider this a marginal upgrade. I'm going to by a few more and I'll update if anything changes.

Great shirt
Color: Beige, Size: Medium
Great fit, seemed like thin to medium weight fabric which is perfect for him. Lil with any linen blends, they wrinkle so it is more of a casual wear. Washes great and is super soft when wearing.

Trashed after one wash
Color: Beige, Size: Small
It’s a great looking shirt. The price is good. The fit is good. But it’s so scratchy that it’s like wearing a potato sack. And after washing it ONCE it pilled so bad that I had to throw it away because it looked like an electrical sander had been used on it. But this is what Amazon has become: bad quality everything.
