I didnt' want to spend the money on speakersox, and orderd from Screamin sacs.
They blow. Thin, non padded material, with a crappy drawstring, for $35ish.
And, they took a 2+ weeks to arrive, although when i contacted them, it sounded like a family medial issue, so can't blame them for that.
Before they arrived, i spent $6 total on 2 black canvas tote bags at walmart. If it wasnt' for the american flag logo on them, they would be PERFECT.
Going to try out the screamin sacs ones, but think i'll probably keep using the softer, thicker tote bags. Just tying the handles together to keep them on the speakers.
If you aren't looking for acoustically transparent, this is a valid, cheap option.
