This pair of 6" Full-Range Ceiling Loudspeakers from Tannoy includes two full-bandwidth, high-power handling, and high-sensitivity loudspeakers built around Tannoy's CMS 3.0 Ceiling Monitor System technology. Based on a dual-concentric point-source driver, the speaker delivers wide and consistent broadband directivity, intelligibility, and an accurate and linear response.

The dual-concentric driver design features Omnimagnet technology and the Torus Ogive Waveguide device, together providing consistent and controlled directivity along with improved high frequency response. Time alignment and coherence between low and high frequencies enhances performance both on- and off-axis. The baffle provides a subtle extension to the wave-guide effect for additional sonic benefits.

The loudspeaker features extra clamp extension to accommodate thicker ceiling panels, and a locking design that prevents inadvertent over-screwing. The magnetic grille attachment enables easy removal and fitting for custom painting. It utilizes a 16-Ohm driver, making it ideal for use in high-performance, low-impedance systems. A low insertion-loss 60W transformer is included, with convenient front switching for taps at 60W, 30W, and 15W, with an additional 7.5W tap for traditional constant-voltage systems.

Each speaker includes a grille, two tile support rails, and a C-ring. This pre-install model is supplied without a backcan.

Features

  • Dual-concentric driver design utilizing Omnimagnet technology
  • Torus Ogive Waveguide device for broadband directivity
  • High power and high sensitivity with extended frequency response and very low distortion
  • Improved LF performance for applications where genuine bottom end is a must

Ten years of ownership…Thank you, Timex!
Color: Black, Size: One Size
Solid watch for everyday wear. I have worn this watch for over 10 years. I let a watch shop replace the battery about every 18 months. Other than the original band (which lasted 5 years) I have had zero problems. Still looks great, rugged and manly😇 Overall I recommend this watch for its value, reliability, simple clear design, legible hands in all light conditions. Great watch!!!

Solid Watch for Everyday Casual Wear
Color: Black, Size: One Size
I have purchased this item other times and I’m quite satisfied with wearing this watch everyday with casual wear. The size is just right not too small or large.

Nice simple effective inexpensive watch
Color: Black, Size: One Size
I just ordered my second one of these. They are cheap, keep good time, show me the date, and last a long time. My last one lasted over 10 years. The only thing wrong with the last one was that the battery needed replacement (I think it was only the second time it had needed a battery in all the years I had owned it) at the same time the band wore out and broke. Rather than buy a new battery plus a new band, I just got a new one. I am hard on watches, and this one stood up very well. I regularly shower and swim with it on, and no problems. It doesn't have a lot of functions I don't need, like stopwatch, multiple time zones, etc. I have found those things more of a bother than a benefit, because any time you bump the knob against something, the display changes and you're always pressing all the buttons multiple times just to get the simple info needed- like what time is it and what is the date DEC 2020 UPDATE - I am ordering another one of these. The last one, I bought in mid 2019. Early in 2020, the date function quit working. By the end of November, the whole thing quit working. I know it's not the battery, because the light still works. So I am reducing my review by one star, and we'll see how well a new one does. The watch before the current one lasted about 10 years, so getting only a little over a year out of the current one is not good. Perhaps the current one just wasn't as good as the previous ones. It's entirely possible that they keep making the same watch out of lesser and lesser materials and workmanship.

Timex. Life is ticking.
Color: Black, Size: One Size
A family member is headed off to Navy boot camp and is required to have a watch-a black watch. But...it cannot be anything in the realm of, be like, or indeed be an Apple Watch. The search began for a simple timepiece. Economy was important since after the 8 weeks of boot camp ended, use of the current watch would be resumed. Enter Timex...(the world's largest manufacturer of watches and mechanical time fuses). During the Amazon search there were all manner of economically (actually cheap) watches noted to be available, so many that it was simply overwhelming. Timex...tried and true since 1854 (just a fun fact, but actually attests to the quality of the company) was the chosen one. A simple but reliable timepiece was required, and certain qualifications were needed. First, it had to be an accurate time keeper and have a second hand, and have a date indicator. Secondly, there had to be an element of water resistance (this is Navy boot camp after all, so water is important!). Thirdly, it had to be black. Fourth, no bells or whistles whatsoever. Finally, a face with 24 hour/military time would be a bonus. This Timex Rugged Core Expedition Analog Watch fit the bill. Upon arrival it was packaged in a traditionally square box the size of the watch, no frills but sturdy enough to ward off damage during shipping. Once opened the first thing noticed was the face of the watch. It was black, with white numerals in both standard and 24 hour/military time, had a red second hand, luminescent hour and minute hands, and date indicator. The nylon band was also black, had ridges, and had a fastener like a belt. At the end of the band were two extrusions which seemed to lock the excess band into place once it was fastened. After wearing a number of days, the watch has kept excellent time matching the Apple Watch. Both watches were worn on the same arm at the same during the day and during sleep. They were worn during regular daily activities, during exercise and during strenuous garden work such as hauling, digging holes, dragging 40 lb bags, etc. Time was checked multiple times per day, and the time on each watch was exactly the same every time checked. The Timex was water resistant during a 5 minute shower and while submerged water. This is not a dive watch but, according to the ad, is water resistant to 50 feet for light swimming. The performance of this watch has been more than satisfactory executing in stellar fashion everything it was stated to be able to do. I can recommend this watch for boot camp purposes without reservation. Top 3 Likes: -Reliable keeping accurate time, has military time numerals -Is water resistant as tested -Is black, attractive with luminescent hands, second hand, date, and light up face Top 3 Dislikes: -The band is stiff and somewhat difficult to latch -The two little extrusions do anchor the band, but are difficult to undo to take off the watch -Only two dislikes!

Timesx quality still rules.
Color: Black, Size: One Size
Excellent everyday watch. Stylish, easy to read, and accurate. Needed a knock around watch and this puts up with it's share of abuse. It's a bit more expensive than some others in this class, but Timex is well-worth the money in quality. I use mine for eveything except when I need something more formal.
