The JBL Brand also carries with it better name recognition for most customers walking in the door as well, and if you do decide to add RE you can start slowly by bringing in a few pieces at a time like a few sets of subs for like a prepackaged combo deal for a sale or something. I definitely wouldn't just jump into RE and load up especially if it's not already known in your market or else you may end up sitting on a lot of product that's not gonna move which in turn will tie up valuable store capital....trust me, I've been down that road before.....
Please don't get me wrong cause I'm a firm believer in bringing in internet brands into your market (afterall I introduced Rainbow, RE, and Sundown to my area) just approach it very wisely....
