No other dealership shows up within the 100 mile limit for a search on RBH's website. I live north of Baltimore MD.
The Adcom is 2x100 at 8 Ohm, or in this case 1x700 at 8 ohms bridged. Should be plenty of power.
Can you compare the RBHs to anything else you have heard? If there is something that is in the same vein that I might be able to listen to, then it could give me more confidence in ordering something without a listening session. Provided the local dealer is actually willing to order a product that they are not going to earn an install fee on.
The big thing is I have slightly more confidence in the sound of something like this than a DIY Dayton solution, and I know I can't replicate the quality looks at all, so it could be worth the extra cash. Most of the other alternatives are simply stupid-expensive for what they are or not up to the task if the price is right.
If your local dealer isn't responsive, you can give RBH a call. Shane Rich is their head engineer. He could tell you anything you need to know about the sub and how it would pair with that amp.
RBH uses a 500w RMS amp with the reference version of that sub, and from what I hear, it can handle more than that. Audioholics has a review of the 10" powered/reference version of what you're looking at. You can get an idea of the driver, cabinet, and crossover quality your dealing with in that review. http://www.audioholics.com/subwoofer...-sx10r-and-s10
As for sound quality, have no concerns there. It's not like speakers where people tend to like certain curves and you need to demo a bunch of models/brands. If there's one criticism, it's that RBH subs roll off more quickly than they need to so they don't play as low as they could. That doesn't bother me too much, as I'd rather have a quicker/steeper roll-off than hear distortion.
I'm not sure where you could find a similar passive sub from a brick and mortar manufacturer. It's pretty unique than you can order powered/passive and standard/reference versions of each of their subs.
