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 ?

I know this isn't music, but the movie 'Push' has some of the best bass I've ever heard integrated into a movie. And I mean really low bass. I think flat response is a bit low, raise the level of the woofer (assuming you're crossing over at 60 Hz or below, mine is at 50 Hz), just move it up a tad.

The scene where he walks into the restaurant and moves the salt (water? can't remember) pouring out from the waitress to the person's food/drink with his hand - that should be very audible. If you adjust the woofer up a bit (not too far!) so that you can clearly hear that as loud bass, then the movie will have a ton of really really really really low bass that is well done - not overdone. I'm pretty sure we're talking 20 - 35 Hz bass, that is some serious soundwork they did. If your system doesn't go to 20, you'll be missing out! :)
Stereo subs are the best and crossing them over where the mains leave off is a must. Having them in the same plane as the midrange driver panel and facing forward will also increase the seemlessness. Placing the subs on a support platform also improves the definition.
Has anyone experimented with horn subs?
I have recently acquired some Soundlab M1's and still have a long way to go to get the total system working properly. One aspect is the bass weight. Soundlabs are reviewed as having very good realistic bass, so a sub should not be necessary.
However before I got the Soundlabs I was going to try out a Klipschorn bass unit that I managed to get hold of - my theory is that it would make the ideal sub. Only a horn has the transient speed and "air" to keep up with a panel????
Any responses?

A horn subwoofer would need a huge chamber. If it were folded and made of concrete (so the walls did not introduce distortion) then it might work but we are talking dimensions of 30 feet or so. If you are thinking ported or TL design then the transient response will not be as good as a sealed box.
What about the Wilson Benesch Torus "infrasonic generator?"

I have yet to hear them, but from what I understand the push pull design and extremely low mass (half an ounce) of the 18" driver supposedly makes it extremely fast, and would seem like a perfect match for stats.

Can anyone comment on them?
