Recently purchased a set of these covers for my pair of SX300 EV speaker cabinets. These are definitely the best quality by far I have seen on the market.
The cover is made of very heavy duty material and sturdily constructed and the internal lining is of a beautiful velvet type material and wine in colour. This makes them look very classy.
They fit the SX300 cabinet perfectly and have a very handy Velcro securing band all around the top of the cover for quick release and closure.
They are made to be very road worthy and heavy duty and also have a large EV Logo on the front side to finish it off.
I would highly recommend these covers to any EV SX300 owner. Thanks again to Thomann for providing a very high quality product and solution.
