I have a pair of EV bags that are made for the SX300's but I didn't try them on the sxA100's yet. The heat sink may be too big, and might stick out.
I use the bags that Mackie made for the SRM450's - they're great because you can store cables and the little angle feet in the pockets. They also have lots of handles and an opening to grab the molded handle on the speaker itself.
I carry all the wires I need to power it up in the same bag ..... it's a beautiful thing.
Even if the EV bags will fit .... you still need to carry at least two cables per speaker. One for AC, and the other for signal.
