subwoofers and panels don't mix


i have yet to experience a subwoofer that mated well with a panel speaker--ribbon, stat and planar magnetic.

each time i have heard a combination of a cone driver with a panel it sounds like two speakers. the blend is not seamless.

can anything be done to make the transition from cone to panel sound like a one speaker system, rather than reveal 2 different driver types ?

Thanks a lot, Ojgalli. I just spent ninety minutes dialing in my sub using the Rives CD2 and the Radio Shack meter. I forgot just what this would do to my two channel.

You are the coolest.
Hmmm... I know this thread is a bit old, just for others reading this and if you haven't gotten anything yet, I recommend the Hsu HO. I may have some of the problems described above but it sounds pretty darn good to me! Using test CD (Stereophile #2) and Radio Shack meter it wasn't hard at all to make it flat with some fiddling.

Try Tarzan (Phil Collins version) track 1 first minute, or Dark Side of the Moon track 1 first minute, then tracks 2 and 3... The Hsu with Magnepans will blow you away! Anyone else using these two together who thinks the Hsu is too slow? It could be, but I can't find a track where it is obvious. It just blows you away!!!! If someone thinks these aren't a great match, what is a track where I can try to detect it?
hi lightminer:

thanks for your comments re the hsu.

i have been advised to use only a rel with a panel speaker.

i have not heard the hsu with magnepans. magnepan has designed a woofer, based upon the mg 20.1, for use with other magnepans. this panel woofer goes down to 40 hz. it is not a "sub" woofer, and perhaps magnepan will design a panel driver which goes below 40 hz. if so, problem solved.
"i have been advised to use only a rel with a panel speaker."

Seems like strange advice to me. There are some very good and fast subs around, and yes, they are not all REL!
I have been using MGllla's with a Vanersteen sub for a long time. The vandy is just as fast as the maggies, if not faster. The combo is seamless with added benifit of the bass panels being cut off at 80hz, letting the middrange panels open up. Panels and subs can and do work well together, just finding a "fast enough" sub is the trick.
