The positives,
The material itself seems durable enough, the stitching seems OK, and its cheaper than the EV option.
The Negatives,
Its made in such a way that the lower last inch of the bottom front of the speaker is given absolutely ZERO protection and with the way these speakers are designed to be lifted.... this means that when you lift the speaker - the front of the speaker drags along the floor surface - anyone who knows these speakers will know exactly what I mean. After just one gig.... I regretted buying these speaker covers - my speakers are scratched already :-(
The covers fit is exceptionally tight indeed - excessively tight - almost leading one to believe that the covers had been designed to fit the speaker without the monitor feet fitted - so I removed the monitor feet of one speaker - and low and behold the speaker cover goes on quickly and easily with no difficulties surrounding getting the "gaps" over the monitor feet! Unfortunately I bought my 4 EV ZLX's purey as monitors so I need the feet. You might say this was a complete design oversight.
Notably its prudent to say that they are equally as difficult to get off the speaker, taking as much time to get you rolling at a gig as it does at packdown.
I do NOT recommend these covers at all and I have wasted about £100 on covers that will be getting replaced immediately, and I can't even get a refund on these as I have used them now :-(
