Having bought a pair of HD10-As I decided to buy the proper covers for a change instead of having cheaper ones made or doing without. Good call as these covers not only protect the cabs but allow me to gig without having to remove the covers which saves time every night (over a year thats a lot, upwards of 250 nights). The clever Zip and flap arrangement means that you can open the front and rear panel which fasten back with Velcro and also access the top handle, side handle and pole mount. They are very light but rugged and protect the cabs from scuffs and scratches and if I decide to sell the Speakers down-the-line they will be in pristine condition. Not so much an additional expense as a Sound Investment! Sorry, couldn't resist that last one.
