Thanks for the info Wayne. I'm not sure what to expect out of a conical front horn loaded 15" driver. I really haven't been able to find much info, though most I've located pertains to 6"-10" drivers. I may be trying to push pretty far into the midrange with the 15", though it is the same upper frequency range as the 15" 2-way setups. Looks like I might have to do some prototyping(better woodworker than engineer!). Take care! Jerrod
