Looking for revel b15a - do i wait for new revel


I presently have F32 fronts, C32 center and S32 rears. I'm running it with the high end denon receiver. Seems to sound fine but really want to add subwoofer - I really want the b15a sub but they seem hard to find. Do I wait for the new revel sub instead of the b15a? I really think that I would be more than happy with the b15a and would rather buy it used to save the money than buying new. Any thoughts or opinions? Does anyone have any ideas of a source where I could locate one?

Your feedback would be appreciated. Tks!

Thanks for your feedback. I've never heard or seen a bad thing said about the b15 or b15a. My preference is the b15a over the b15 because of the easier use of the back panel. I called revel and also a revel dealer and didn't as much info on the new subwoofers as I wanted to. I'll probably call back Revel and try finding someone else with more knowledge and specifics on the new subs. In the meantime, if any one knows of a b15a out there for sale I would be interested. I prefer black since my speakers are black. Theo, Tks for the lead on the sub, I will follow up on that one.
If you have a receiver or pre-pro with room correction the back panel becomes irrelevant. That's why Revel has dropped all EQ from the newest subs. I now never use the EQ on my B15 after an upgraded pre-pro.
Clarification: I was talking about the back panel proper with the manual EQ dials that used to be there. EQ is now outboard and is not the 3-band (manual) parametric EQ. Thanks for the clarification Kal! After doing it old school for years with the Revel CD, meters, and software, it's a nice thing to have all that stuff automated without manual dials.
Even more interesting is that this same sophisticated EQ is also included in the less expensive Performa subs.
