mac48025,
When I talked at length with Tim, he said I'd get great results if I put an E card and stuck it with magic mounts to the back of the magnet on the top woofer and another on the bottom woofer of my VMPS RM 40s. It would then affect the sound across the entire speaker including crossover. For those who don't know, there is a woofer near the top of the 66" cabinet and one near the bottom. So 2 cards to each speaker. If your speakers have 2 cabinets to each side, stick one on the back magnet on the inside of each cabinet. If you have an separate area where the crossover is located, put one there also. This would take 6 cards to do both sets of speakers.
Your idea of putting one on the outside of the speaker would offer a little improvement, just not near what inside would do. If you're going to spend the money, you might as well get the most bang for your buck.
