The horn path length is 9.3 feet. Upper frequency rolloff is due to mass rolloff, front chamber volume and horn folds. Mass rolloff, front chamber volume and flare are incorporated in the Hornresp model, but the specific folds aren't. That's what tends to make it rolloff a little lower than what the model shows.
