I am working on a three way using a midbass horn with a 2461 mid and 2405 slot. Eventually there will be a sub as well, but for now the mid bass horn goes low enough to satisfy my tastes. I have a couple horns that I am experimenting with the 2461 driver. One is a Community/Rauland BRH-90 and the other is a SFA/San Fransico Audio horn very similiar to the 2345 horn used in the 4663 cabinet. Any thoughts on which would work better. The bas horn is using a 12" driver down to 80hz safely although I can squeeze 55 on a pinch I am thinking of crossing it at about 800hz. Does this seem right?
