That was my take on it. The 802/902 DRIVER is capable of going lower (at the cost of some power handling, and the need for a steeper crossover), but the 811 FLARE isn't, really. Don't wanna get close to unloading the flare on the bottom end...

I have never had a ringing problem with 811B horns as long as they are bolted in to an enclosure. The 511B horns do ring though if not dampened. Mine usually don't ring because they are always full of stuff. Altec horns are a handy place to toss nuts, bolts, cords, adaptors, guitar picks, change, Etc. Etc.

If you can get past the ringing thing they are truley great sounding horns when used down to their limit.
