The CBT 70J-1, with Constant Beamwidth Technology, represents a breakthrough in pattern control consistency, utilizing complex analog delay beam-forming and amplitude tapering to accomplish superior, consistent vertical coverage without the narrow vertical beaming and out-of-coverage lobing that are typical of straight form-factor column speakers.

The CBT 70J-1 combines Constant Beamwidth Technology with a physical J-shaped curving, resulting in a very well controlled progressive line array with asymmetrical vertical coverage. The asymmetrical coverage produces a higher concentration of sound with a tighter pattern from the upper half of the array and a lower concentration of sound with a broader vertical pattern from the lower half of the array. This sends more sound toward the far area of the room than to the near area of the room, resulting in more even front-to-back SPL levels than would be the case from a traditional speaker or column that projects symmetrically in the vertical plane.

The two-way coaxial design provides a wide 60 Hz – 20 kHz bandwidth. The low-diffraction baffle eliminates frequency response irregularities that could otherwise occur due to baffle discontinuities. The thick, heavy-duty aluminum grille stands up to portable/event applications while allowing for rust-free installation outdoors.

The slim, compact design fits well into virtually any architectural decor. The 70 cm (27.6 in) tall line array height provides consistent pattern control throughout the intelligibility band, making the CBT 70J-1 work well in difficult acoustic environments. 

Features

  • Asymmetrical vertical coverage sends more sound toward far area of room to make front-toback sound levels more consistent.
  • Components: Sixteen 25 mm (1 in) soft dome tweeters and four 125 mm (5 in) high-power LF drivers, arranged coaxially.
  • Patent-pending Constant Beamwidth Technology provides constant directivity up to the highest frequencies and reduces out-of-coverage lobing.
  • Vertical pattern coverage switchable between 45° for medium-throw coverage and 25° for long-throw applications.
  • Switchable voicing provides flat response in music mode or mid-range presence peak in speech mode.
  • Dynamic SonicGuard overload protection of HF devices
  • Swivel (pan) / tilt wall bracket included.

Works brilliantly with Steam Deck!
Size: USB C to Ethernet Adapter, Size: USB C to Ethernet Adapter
I bought this specifically for a Valve Steam Deck. I recently got a gigabit fiber connection and wanted to take full advantage of it when downloading games on the Deck. I took a gamble on this adapter knowing that Linux generally has incredible driver support without much, if any, configuring. I installed it into the Steam Deck's USB-C port, hooked the other end up to my network switch, and the Steam Deck instantly registered a new wired connection. I didn't even have to go into "Desktop Mode" for it; it all worked flawlessly in the "Gaming Mode". I downloaded a 15GB game in about 3 minutes with the Deck maxing out at 880Mbps. The device itself seems well built with a braided cable and gray anodized aluminum enclosures on each end. It's small and compact so it'll fit nicely in the Steam Deck case's little pouch or in that drawer that every house has that's full of cables, adapters, and dongles. It seems as though it's good value for money as well, like every Anker product I've purchased, but time will tell if something goes screwy down the line.

Great way to connect my Ethernet to my MacBook Pro....
Size: USB C to Ethernet Adapter
Needed to direct connect to my Modem / Router, but my MacBook Pro, being more modern, and slimmer, doesn't have an Ethernet port anymore (thank goodness). This worked perfectly; just plugged it in and ripped...definitely Plug-n-Play for my Mac. Quality is good (what else do you expect from Anker).

Easy to use Plug and Play
Size: USB C to Ethernet Adapter
The item works great. I was having issues with video conference calls even with strong wifi in my house. I bought this adapter due to my HP laptop not having an Ethernet port. This worked great right out of the box. It was detected automatically and as soon as I plugged the Ethernet cable into the adapter, my laptop immediately switched over to that and my internet became more stable.

It's functional but not as fast as I expected.
Size: USB C to Ethernet Adapter
For Android phone Samsung Flagship Galaxy Series phones... at best getting 136 Mbps, which is 0.136 Gbps. But it is working and allowing me to transfer files within my network. No where near a Gigabit transfer. I will likely keep it because I have another use case for it (a faulty Ethernet on a laptop) and don't get me started with the abyssal wifi speeds on laptops. This deserves at best 4 stars.
