I got the 34in one on Jim's recommendation. I have the Stealth 10 Ultra HD. Bar dimensions are 33.7in long x 3.7in tall, x 3.9in deep
per the website.
It fits decently. I have my bar mounted "upside down", so the drawstring doesn't quite work like it's supposed to. The velcro is far longer than it needs to be so I'm going to trim it down next time I'm near the boat with a pair of scissors. I also run (3) pairs of
these elastic cord with a ball bungee things around the sound bar while towing, just to prevent fabric flappage and make sure it stays where I put it. It would probably be OK without them, but it's a quick addition while packing up to tow. The draw string does "draw" fairly well, and holds it's place so far. Material is a little thinner than I expected. I had a "canvas" or "neoprene" in my head, but it's more of a thin stretchy nylon or polyester. Not bad, just thinner than I thought.
Main reason I wanted the sock was to keep the bar from whistling. My biggest complaint with the bar has been that it whistles LOUDLY while towing. When we moved from the pickup to an SUV it was unbearably loud inside the vehicle at highway speeds. Before we did the 11hr tow to FL we wanted that remedied. It's worked well for that with the added benefit of keeping bugs out of the cooling fins on the leading edge of the bar as well.
I paid him $45 shipped for the cover. I'll snap some pics for you tonight when I get home.
Here's the best pic I have of the soundbar mounted on the boat. Nevermind the ropes, that's from the infant swing we had onboard the season we put the soundbar on.
