Remote Volume Control for a Sub Woofer

Hello All,

I was looking for a past post I read where people were recommending remote volume controls for a sub but couldn't find it.  Some good recommendations were given and I was hoping that those that responded, and also others who could recommend, might respond to this post.  I have limited space to place my sub.  It now resides under a desk.  It's an RSL Speedwoofer.  Some music plays with too much bass on it, and some not enough.  Being that the sub's controls are on the rear of the unit I find myself having to lay on my back, under the desk, to make adjustments.  Then, I crawl out and hope the adjustment is to my liking.  What a pain!  I was almost going to post a question to see if anyone knew of a good preamp, with a sub out jack, that would have a separate sub volume control on it's front panel.  I've never seen one.  Anyway, the idea of placing a volume control, with a hand held remote, between my preamp's (an NAD C 165BEE) sub out jack and my subwoofer greatly appealed to me.  Any recommendations would be greatly appreciated!

Thanks
