I own a pair of 811's and love them for nostalgia's sake. They sound nice on axis too. But I do not have any designs that use 811 horns. All my designs use either the H290 or my own wood horn. These are much shorter than the 811, and that's a very important consideration in crossover design. They also provide much more uniform directivity, so you'll probably want to build the speaker as designed.
