Up 4S is a discreet, two-way, passive 4” speaker delivering consistent coverage and full frequency sound to a wide range of cost conscious, commercial environments from hotels and concourses to retail outlets, bars and restaurants.

Up 4S features a 4” (105mm) low frequency driver paired with a 0.7” (20mm) silk dome tweeter. It is suitable for both high quality speech and music reproduction.

The Pendant 1 and Grille 1 accessories offer further flexibility in installation and applications, allowing you to either elegantly suspend Up 4S speakers as stylish pendants or achieve a sleek, bezel-less grille appearance. These accessories are available in both black and white, helping to blend into any architectural environment.

The wide 150° conical coverage of Up 4S makes it particularly suitable for low ceilings and reduces the number of speakers required for even coverage leading to a reduction in installation cost. A shallow steel back can allows installation in ceilings with minimal cavity depth. An integral fixing system is included to achieve a simple and clean installation.  Up 4S has a steel back, perforated steel grille and finished in neutral white.

Each Up 4S can be run on a series of 70 or 100 Volt taps or at low impedance. Tap selection is via a rotary switch behind the removable grille.

A SmartAmp or powered Zone will provide amplification, optimal sound performance and loudspeaker protection via presets. When coupled with a Zone and WebApp, system set up and end user control is straight forward, and can be further supplemented by ZonePad wall controllers.

Cheap, screw holes don't line up, screen is to short, and bars take WD-40 and a mallet
This has been my worst purchase on Amazon ever. DO NOT BUY. My first issue was that bars #4 and #5 would not go together, I ended up buying WD-40 and a mallet and that kind of got them together. Now I went to but the screen on (which is almost see thought) and the screen is to short. I can't attached the bottom bar to the tall bar. The screw hole is in the wrong spot, so the screen is not secure. No amount of pulling on the screen will make it grown .25" longer. Since I can't get the bars secure the walls are not steady and fall over easily. The feet did go together very nice. I can't return them according to Amazons policy. I bought 2 sets. I'm not going to try to build the other set I have. And I can't take apart the first set, since the bars are so tightly together. Also the polls have rust on them.

Very Poor Built Quality
Color: Black, Size: 3-Panel
They use cheap tarp like cloth that you might find on a tent, so it is not suitable as a teleconferencing background without blur applied. The legs are flimsy and lack rubber feet, so it will scratch floors. The tubing is flimsy and very hard to move and adjust. This is only good if you are setting it up somewhere like a gym or a garage.

Versatile Room Divider With Easy Assembly and Strong Coverage
Size: 3 Panel 12FT W
I picked up this Siebwin 3-panel folding room divider mainly for privacy and room separation, and overall it works very well. Assembly is very straightforward, and the divider can be set up, taken apart, and stored without much effort. The fabric quality feels good, and the frame construction is stronger and more stable than expected. The support tubes especially feel well built and help keep the divider standing securely. One feature I really liked is the flexibility of the design. The panels can be used together as a complete divider or separated depending on the setup and available space. That makes it much more versatile for different room layouts or temporary privacy needs. The coverage is also very good, and the size matches the manufacturer’s description accurately. The fabric blocks light and background visibility well enough to provide solid privacy without feeling overly heavy. The wider feet also help improve stability compared to thinner folding dividers. Another positive detail is that everything arrived complete with no missing parts or damaged pieces, which made assembly much easier and faster. Compared to cheaper privacy screens, this one feels more durable and easier to customize depending on the situation. In terms of value for the money, it feels like a very practical and worthwhile purchase considering the size, flexibility, and build quality. Overall, a versatile and well-built room divider with easy assembly, strong privacy coverage, stable construction, complete included parts, flexible panel configuration, and excellent everyday functionality.
