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.

Ten Stars
I only use the left two colors but I expected that since I wasn't sure which one(s) would work. They are a great concealer of dark circles. I use the lightest one on the bottom and then touch up with the darker of the two. They don't look caked on and, in fact I can wear them alone without any foundation or powder on my face! And, they lay on top of the fine lines, hiding them somewhat. The brush is great for applying. I have tried many concealers and this is the the best by far.

Reliable protection that stays put during workouts!
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
I’ve tried many expensive name-brand sunscreens, but this Amazon Basics version performs just as well, if not better. It’s become my go-to for morning runs and trips to the beach because it actually stays on even when I’m sweating. Why I gave it 5 stars: Non-Greasy Formula: Unlike other sport sunscreens, this one absorbs quickly and doesn't leave that heavy, sticky film on my skin. Actually Water Resistant: I’ve used it for laps in the pool and long hikes; as long as I reapply as directed, I haven't had a single sunburn. No "Sting": One of the best things is that it doesn't run into my eyes and sting when I start to sweat—a huge plus for runners. Great Value: You get a generous 8-ounce bottle for a fraction of the price of "premium" brands. The fact that it’s formulated without Oxybenzone is an added bonus for peace of mind. If you’re looking for effective, no-frills sun protection for an active lifestyle, you can't beat this. It’s a staple in my gym bag now!

Great value and very practical
Style: SPF 50, Size: 8 Fl Oz (Pack of 6)
This sunscreen is a great value for the price. The SPF 50 protection works well and the lotion applies smoothly without feeling too greasy. It absorbs nicely and provides good coverage for outdoor activities. I especially like using these bottles to refill the sunscreen dispensers at my Airbnb for guests. It’s convenient, reliable, and affordable when you need multiple bottles available. Overall, it’s a solid everyday sunscreen and a very practical option if you need good protection at a reasonable price.

good price for good product. applies well, shake and store upright
Style: SPF 50, Size: 8 Fl Oz (Pack of 1), Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
I believe it is equal to the name brands It is 50 SPF Sun Protection Factor so it offers strong UV A and UV B protection which are the 2 ranges of sun rays that do the skin damage and burning. It is an easily absorbed lotion that when rubbed goes into the skin and is not visible. It is thick and goes on with a non shiny, non greasy, solid thick feeling which is what we need for it to stay on as long as possible. It feels good after being rubbed in in that it feels dry and not overly greasy or with no shine and sheen. It is a good product and offers burn protection to me in some clear-sky strong sun uses. Reapply after entering the pool water or swimming laps and after an hour (all sunscreen labels say reapply after 80 minutes which I believe is per recommendations of the federal FDA or some medical studies). I reapply often and I still get tanned but I do not want to burn.

Survived the sun like a pasty legend
Style: SPF 50, Size: 8 Fl Oz (Pack of 1)
I bought this sunscreen because I’m basically a human marshmallow — one hour in the sun and I’m toasted. This Amazon Basics Sport SPF 50? It’s like armor for the pale and easily crisped. I slathered it on before a full day of hiking, sweating, and pretending I enjoy direct sunlight, and guess what? No burn. Not even a pink glow. Just victory. It goes on smooth, doesn’t feel greasy, and somehow stayed put through sweat, water, and my dog licking my arm. It’s fragrance-free, which means I didn’t smell like a coconut smoothie or a chemical spill — just clean and protected. Pros: • High SPF that actually works • Sweat and water resistant — like, impressively so • No greasy residue or weird smell • Affordable and comes in a big ol’ bottle • Didn’t turn me into a lobster (the bar is low, but still) Minor feedback: It’s not fancy or trendy, but honestly, I’m here to not burn — not win a skincare award. Also, it takes a bit of rubbing in, but once it’s on, it’s locked and loaded. Final thoughts: If you want solid sun protection without the drama, this stuff delivers. Whether you’re hiking, swimming, or just trying to survive summer, it’s a reliable sidekick. Would absolutely buy again — my skin demands it.
