Being in NJ, the path of least resistance might be Steve Guttenburg, first. He stated that if he doesn't like a product, he won't make a review video of it and will just send it back so not to hurt those brands. It could be a good opportunity to meet him in person while hand-delivering the gear and he might record an interview with you, as well.
You could also explore partnering with any local speaker manufacturers like Devore to see if that can be beneficial to both of you.
