The Audison SR 4.500 4-channel amplifier with crossover features great power packed into ultra-compact dimensions (130 W x 4 @ 4?).
As far as the electronic design is concerned, every aesthetic and functional detail of the Audison SR 4.500 has been taken care of, resulting in a compact amplifier made of extruded aluminum with rounded corners, which facilitates the installation of the product in narrow spaces. Thanks to the generous heat sinks on the two short sides of the amplifiers, there is no need for internal cooling fans, which often cause noise and dust accumulation. In keeping with tradition, the SR amplifiers confirm their vocation for versatility by including on all models a complete filter section, suitable for any kind of audio system configuration. The controls, protected by a satin-finished aluminium panel, are located on the top panel of the amplifier, so that they can be easily reached from above, even after the product has been installed. When the system includes an Audison bit processor, the filter section can be totally excluded.

So beautiful and stylish
Size: with legs, Size: with legs
Very happy with this shelf! It has a clean, modern look, and the rounded edges make it feel more stylish and cozy in the room. Assembly was quick and straightforward — the instructions were clear, and all parts fit perfectly.
The unit feels sturdy and stable, with no wobbling. The cubes are spacious enough for books, storage boxes, and decor. I also really like the removable back panels — they give you flexibility to change the look or keep some sections open for a lighter feel.
Great value for the price. I’m very satisfied with this purchase and would definitely recommend it!

Stylish Storage Shelf With Great Stability
Size: with legs
This cube organizer ended up looking much better in person than expected and gives the room a clean modern look. The curved edges and raised wood legs make it stand out compared to basic square shelving units. Assembly was straightforward and once put together it stays very sturdy without wobbling around. The cubbies are a good size for storage bins, books, decorations, or kids toys. I also like that the bottom sits high enough off the floor to easily vacuum underneath. Great combination of storage space and furniture style appearance.

Works great
Color: White
Works perfect. Charging one iPad, two phones, headphones. Makes it easy to plug in behind night stand because of the angle plug in. USB cable plug right in without the cube adapter. Also have an air mattress plugged in. Ordered a second one for the living room behind the couch.
