Live sound and playback capabilities with 3-channels mixer and Bluetooth.
The dB Technologies ES503 is the ultimate portable column speaker PA system. Perfect as a portable PA system for live sound as well as playback applications, ES provide a simple yet powerful plug-and-play solution for solo musicians or small bands, and is the must-have sound system in the touring DJ equipment, thanks to a built in digital mixer and a stereo Bluetooth audio receiver.
ES503 is a 1000W Power Amp Peak sound system composed by 2 slave 4x 3" full-range tops and 1 master 12" subwoofer. dBTechnologies's components and design allow an amazing SPL/size ratio: 95x355x137 mm and 1.9 kg for the tops and 465x400x430mm 16,4 kg for the subwoofer for an overall 121 db SPL. The sub hosts a Digipro G3® amp module with auto-range PSU and a 3-channels mixer with Bluetooth connection. A powerful DSP manages all function of the on-board digital mixer, making the ES503 a real gem in terms of sound performance and versatility. The internal design of the tops allows an asymmetrical vertical coverage (thanks to the Logarithmic Curved Column Array technology) and a unique "double ringed" phase plug widens the horizontal coverage and guarantees a perfect voice intelligibility. This allows ES503 to adapt to any situation, both with a seated or standing audience.
ES503 is the most eclectic among portable systems, allowing 3 different configurations suitable for hundreds of different occasions:
- 1 MONO MODE: The two satellites are connected top-on-top (thanks to a quick and easy slide connection system) and are placed on the subwoofer through a D25mm pole.
- 2STEREO MODE:Each satellite is placed on a tripod
- 2b STEREO MODE: 1 Satellite on a pole, 1 on a tripod
- 3 DOUBLE COLUMN MODE: a ES503 system in mono mode becomes the master for a second ES503 feeding the signal thanks to the integrated balanced output channel. This way, both system are driven by the master's on board mixer and any setup is guided through the master's OLED display.
The ES503 is equipped with a three-channel mixer, and a built-in Bluetooth™ stereo module, which receives audio from devices such as mobile phones, tablets or any other audio device.
The bass-reflex subwoofer houses a 12" woofer and the amplifier module. In addition to the input connectors and controls of the user-interface, there are two Speakon outputs and a VDE power connector. The enclosure, sturdy and stylish, is made of birch plywood coated with a durable scratch-resistant black coat, which makes it truly road-ready. Two handles (one per side) help easy transport.

Good For Deep Sinks
Color: Silver
This item is very sturdy however the piece on the outside that holds your rag tends to slip or lay flat all the time. The adhesive is very strong to the point where I needed to use a tool to get it off while moving, so you’ll never have to worry about it popping off your sink! I can only figure that this fits in all sinks because at my old apartment I had a very small sink the only thing I didn’t like due to having a small sink my rag was always touching the bottom of the sink and there wasn’t any space left in the side I had it on. If you have a big sink I’d suggest this item because it looks nice and it gives your wash cloth and sponge a home in the kitchen!

Worth every penny!!
Color: Black
This kitchen sink caddy was exactly what I wanted. It's well made and small enough to fit on my new sink. It holds soap, dish rag or small sponge, drain stopper, and my two scrub brushes. Looks good, too

Great addition to my minimalist kitchen!
Color: Black
This kitchen sink sponge holder is simple yet highly effective. It keeps the sponge neatly in place, allows it to dry quickly, and makes the sink area look tidy. The sturdy material and easy-clean design make it a great little addition to any kitchen.

Strong sturdy reliable and versatile
Color: Black
This is a great little side piece to use for your kitchen sink or bathroom mine is in my kitchen sink it works great it sits on the side it's the perfect length holds my scrubber soap and other stuff I need instead of using a makeshift bowl. It's sturdy rust-resistant and I put it through the tests it gets wet every time I do which is every day in this house. You can use it for just about anything. There are no suction cups on it but there is a gray under it that catches all the loose water which is also very convenient. It looks modern and compliments most sinks and kitchens well

Good Quality but Limited Space for Multiple Bottles
Color: Black
This organizer is decent quality, but it ended up being smaller than I expected. For reference, I usually keep the following items at my sink:
• Dawn squeeze dish soap
• Mrs. Meyers hand soap
• Dr. Brown’s bottle soap
• A sponge
• A bottle brush
All of these items fit comfortably in my previous sink caddy that I bought on Amazon. Unfortunately that one eventually started peeling and rusting, which is why I replaced it.
With this one, the narrow section on the left side limits how much you can actually store. It works well for the brush, but it reduces the usable space for bottles. Because of that, fitting multiple soap bottles plus a sponge is a little tight. I also think my previous organizer was slightly wider, which made a bigger difference than I realized.
One feature I do like is the removable plastic tray on the bottom. It catches water well and keeps the counter from getting messy, which is a nice touch.
Overall, it’s usable and I will keep it, but if you normally keep several bottles and tools at your sink like I do, I would recommend paying close attention to the measurements before ordering.
