Is demo'ing a new sub complicated? I went to Music Lovers in Berkeley, CA yesterday and demo'ed the Revel B15. It was the first time I heard it. I was impressed with its response with the Beethovan's 9th Symphony. Here's the problem. They didn't have the B&W S805's to pair it with, which is what I have. Should I take in my 805's to the store? Plus, my normal dealer here in Sacramento has Rel (can get to demo) and B&W subs. (800 no 850). I can demo them with the S805. Am I really going to be able to tell what I like? I mean, the B15 was nice, could I really tell what I was hearing yet? I am not sure. Questions: Should I just demo the B&W 800 or ask them to get the 850 and should I take my S805's to Berkeley and demo with the Revel B15? Anybody got experience with the Revel's they would care to share?
