Just purchased a pair of these Gator GPA-450-515's to case my Mackie SRM450 v1's. Didn't have the funds or the storage space to flightcase them so went for covers instead. Very impressed with these covers, I'm a fan of Gator stuff as it is, but these are a lot more rugged and sturdy then they look in the picture and description which I think is a massive plus. Unfortunately no pocket for carrying any extra leads or bits and pieces. Always useful to have space for an XLR and IEC lead on smaller gigs, but not the end of the world. Would definitely recommend you buy these if you're looking for a cheaper alternative to flightcasing your speakers.
Purchased these to protect our Mackie SRM 450s. They are padded and so offer good protection from knocks and bangs when you are transporting the speakers around. They also help to protect the inside of the vehicle you are transporting them in which is a plus.
They unzip totally to leave the case flat which is helpful when you are trying to manipulate the speakers into the case on your own. Zips are strong ? we have probably done 150 gigs with these so far and they have held up. There is a carry strap which works but is a little awkward due to the size and weight of the speakers. We normally end up carrying them using the speaker handles which are accessible through holes in the case. One of the reviews says that only one side is accessible. On our covers both sides are the same and so I don?t know why theirs would be different ? unless there is some design change? I think these are good value and would buy them again.
