The CMS 503DC PI is a full bandwidth 240-Watt high sensitivity loudspeaker that utilises our third generation Ceiling Monitor System technology (CMS 3.0). Thanks to an all-new proprietary 5" Dual Concentric point source driver with Omnimagnet technology on a Torus Ogive Waveguide, the UL certified CMS 503DC PI delivers wide and consistent broadband directivity with enhanced intelligibility – plus highly accurate and linear response.

Good strong forks
Number of Items: 500
I was looking for some good, strong forks for our office breakroom. Strong enough for Texas BBQ or anything else we might throw at them. These forks can handle the job! The spoons and knives are also very good, and I also order our10 and 16 oz paper coffee cups and lids from Comfy Package. Good products at a good price - hard to find!

Very Sturdy Forks
Number of Items: 500
These forks are very sturdy and similar in quality to Dixie heavyweight forks. They are hard plastic, not maleable, so they hold up well to hot food and can be used to "cut" foods such as lasagna. Good product.

Two packs no breaks
Number of Items: 500
I've ordered two packs of these now for lunch. Over the course of 2 years. Works very well. Never had a fork break. Biggest complaint with other brands is I've had forks break.
