No. There is an Extremely talented individual here that has designed and has a patent for speaker pods for the slingshot. I'm not sure where he is as far as going retail on these yet, but I'm sure if you ask, he'll be able to provide you with some cool pictures and maybe even a price. I'm sure he'll see this and say something to you Jim.
I think I know that guy!
I have not made anything as far as side pods yet. I have made a top mounted sub enclosure. T.M.S. SUB PODS
(top mounted slingshot sub pod) I have had many people ask for pricing, but at this time I am still trying to figure that out. A few of the forum members have heard the one I have in my SS and I'm sure they can attest to the sound of it.
That looks awesome! Much better than protruding from the door and not being able to recline your seat fully... 
Still takes the storage, but very nice! If I ever do put a sub, I'll also need some fully functioning, Corbin bags (version 12.0 that hopefully have no issues at all unless you crash your Slingshot) to get some storage back. That would also take care of the need for a fender... Oh, $$$$ 
Yes I hope I'm on kenny_h order list already. What I was talking about is the one beside the seat. I have the factory pods next to your feet. Wanting the ones next to your hip.
