The Martin Audio A55B 5.25 Inch Passive Two-Way On-Wall Loudspeaker is a two-way passive speaker with an elegant design that is perfect for architectural environments that require high-fidelity sound from an unobtrusive, ultra-compact enclosure. It brings class-leading performance, reliability and value to a wide range of commercial sound applications from retail outlets, bars and restaurants to corporate offices and convention centers.

The A55 is the perfect choice for background and foreground systems which require superior performance. Its Martin Audio signature sound characteristic also provides a seamless sonic transition within a multi-zoned complex using larger Martin Audio systems such as CDD or Blackline X.

Comprising a 5.25” (135mm) LF driver and a 0.75” (19mm) silk-dome HF driver on a 110° x 80° horn, it handles 50W AES, 200W peak and can produce 113dB peak output at 1 meter. It has a smooth frequency response and strong bass reproduction that extends down to 65Hz.

With a nominal impedance of 16 ohms, multiple speakers can be driven in parallel from a single channel of a low impedance amplifier, such as the Martin Audio VIA2004, thereby maximizing efficiency and minimizing cost. For full-bandwidth protection, the low and high-frequency sections are individually protected against overload.

helps my swelling in my ankles and feet
Color: Black, Item Shape: Classic
I was having issues with my feet swelling because I sit all day for work. After using this my feet don't swell like they did. The product is also comfortable. I would recommend this foot rest. The best part is its two and one. You can use the rest or turn it over and rock it with your feet which helps. The foot rest is sturdy and durable.

Very Comfortable & Useful Foot Rest
Color: Navy, Item Shape: Teardrop
This product is a lifesaver for me since I sit at my desk for hours on end. Just the simple act of raising my feet up onto this heavenly soft foot rest makes a huge difference in how my back, legs, and feet feel at the end of the day. Very high quality materials and workmanship. You can also remove the zippered cover from the memory foam pillow and wash it.

Very Comfortable and Supportive, Minor Flaws
Color: Gray, Item Shape: Classic
I’ve been using this ComfiLife adjustable memory‑foam foot rest under my desk for a few weeks now, and it’s made a noticeable difference in how my legs and lower back feel. What I Like: The high‑density memory foam is plush but still supportive, conforming nicely to my feet whether I wear shoes or sit barefoot. Under Yours +2 ShipItFurniture +2 The adjustable height feature is super helpful — you can add or remove a base layer (2-inch detachable bottom) to set the footrest exactly where you want it. ComfiLife +1 The removable cover is machine washable, which is great for keeping it clean. Under Yours The bottom has a non-slip rubber surface, so it stays in place nicely under my desk. ComfiLife It’s multipurpose: you can even flip it over and use it as a rocker or support it under your knees. Under Yours What Could Be Better: Because it’s memory foam, it compresses a bit over time—not a deal-breaker, but you’ll notice it loses some height after prolonged use. ShopSavvy While the height adjustment works, I found it a little less stable when fully extended. ShopSavvy The fabric cover can collect dust or dirt, so you might need to clean it more often than a plastic footrest. Fakespot Overall: This footrest is a strong pick if you spend a lot of time sitting at a desk and want something soft, supportive, and adjustable. It’s not perfect, but the comfort and ergonomic benefits are absolutely worth it.

Comfortable, Adjustable, and Great Value!
Color: Gray, Item Shape: Teardrop, Color: Gray, Item Shape: Teardrop
This footrest is exactly as described. The two-piece design offers excellent flexibility, allowing for multiple configurations to suit different needs. Both pieces are comfortable and adjust easily as intended. I’m especially glad I chose the teardrop style—it works perfectly for my setup. I’ve experimented with several of the suggested configurations and can see how the various options would accommodate different preferences and ergonomic needs. For me, this was an ideal choice. The overall design and construction appear to be high quality and durable. When used with socks, the surface is very comfortable, and the base grips the floor securely when in use. Overall, I believe this product offers great value for the price.
