I think kkm is on the right track. I don't think the brightstars are magic, but good stands make a big difference.
However, I find that "energizing" the second voice coil makes for more controlled bass. You get the double benefit of power & control (the magnet acts no matter which way the woofer is moving). But, it does take some time to dial it in (just like putting in a separate sub)--if memory serves, the settings "out of the box" were way way off from where they ended up.
I also found that speaker cable made a big difference for the second voice coil, but this may not be universal (I tried Nordost SPM).
Get something and put on some nice Mark Miller, or Jaco--you will hear the difference!
happy listening,
