This cover should do the job - it is more like an addon accessory for dust protection during storage and transportaion but it is definitely not a must. It is made of high quality material and will offer a moderate protection during transportation, i.e. from scratches, etc. It is not suitable to use when the PA is running as it mutes the sound significantly - I kind of hoped that it would not. However, it will probably keep the speaker safe from the kids at home, they really enjoy painting and placing stickers everywhere.
