In combination with a speaker clamp kit (such as Thomann 103483), the Monacor loudspeaker cover provides a very quick and effective means of mounting and protecting loudspeakers in a home-made cabinet (as in my case) or perhaps to repair a commercially-made cabinet. The Monocor product is light but strongly made and I am confident that it will protect my speakers from impact with other equipment when loading and transporting my gear. This type of cover has been on the market for some decades. It was about 30 years ago that I bought my first and I've used several since. Over the years, I have never lost a speaker as a result of physical impact with other gear. It is possible that a sharp object, such as a screwdriver, could penetrate the cover and damage the loudspeaker and a finer steel mesh might be an improvement,,,,but I suspect that this would increase the weight and price of the cover.
