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.

Nice warmer.
Color: Black
This thing gets hot! I've had one incident with it. It was on without anything showing on the LED panel. Went to move it and got an unpleasant surprise... Sorry, but one star off for that. Other than this incident it works just fine. Keeps my mug of whatever warm or hot as I select. Recommend it. I'm sure the incident I suffered was a fluke.

Daily Must-Have for Working at Home!
Color: Black
The KitchekShop Coffee Warmer is an item I use daily. I had an old warmer that had a switch on it and the light burnt out. I would always forget to turn it off and sometimes it would be on overnight while I slept or when I left my home office. Yikes! Fire hazard, right?! So I purchased this one and I love it. You can see a little review I made. This has a display to show the temperature setting on it while it's on. It has a power button, a timer button for up to 12 hours, and a temperature button. The timer is awesome because I can set it anywhere between 1-12 hours to automatically shut off and not worry about it. I usually set it for the time I KNOW I will be leaving my office so I can't forget about it. I also love the 4 temperature settings. I typically keep it at the second setting of 145 F which is the perfect temp for me. Sometimes, if I am bringing on a beverage that already started to cool a bit, I will bring the temp up to 167 F or 185 F to get it warmer faster, then set it back at 145 F. And once in awhile, if I only have a little bit of beverage left, I will be it at the lowest temp of 131 F so that it's not scalding hot when I drink it. It doesn't take up a lot of space and it's best used with mugs that have a flat bottom. If you have a concave bottom mug, the heat doesn't distribut as evenly on the mug and it won't heat as quickly and evenly. This is no fault of the product, it's science. I will say that I had an issue with the first warmer I purchased. It was not heating up as it should. Customer service was phenomenal and sent me a replacement and the replacement has been perfect. Even if this one goes out, I would continue replacing it because of the functionality, appearance, and quality.

LOVE IT!! No more lukewarm coffee!!
Color: Black
I have a glass coffee mug with a slight ridge on the bottom so I wasn't sure if this would work with my mug. It did wonderfully! I found that the lower temp. is too low for how hot I like my coffee, but the next one was a bit too high, HOWEVER, it was drinkable I just have to blow on it a little. But, even if I forget, it's NOT TOO hot to where it hurts. It's VERY easy to use, and I'm old, hahaha

Keeps my coffee to temperature
Color: Black
it works great at keeping your hot drinks hot, unfortunately you have to remember to turn off once you are needing to step away or leave for the day as it will not turn off on its own until about 8 hours later, drying the coffee or drink and leaving a dry paste in bottom of cup.

it keeps my tea hot for as long as I want it
Color: Black
I really like the cute design of this mug warmer. I bought two so my husband and I can use them at the same time. My larger mugs fit perfectly on it. The four temperature settings, timer, and auto shut-off feature are all very useful. Now I can take my time and truly enjoy my tea.
