OK here's the back story. I am a die hard Mac user, but I have just very recently bought a PC to use for audio related things. Therefor I have not been able to play with hornresp or Akabak enough to figure anything out. Honestly just keeping the PC straight is hard enough for me!
I got a pretty good deal on a pair of 18 sound 21LW1400's a while back. I planned on building a pair of single 21's for a small club PA (rock/country/folky). I was sitting last night playing with Sketchup and WinISD when the thought occured to me, "Why not tapped horn?" So what I'm looking for is for some kind soul to tell me if this driver is suitable for a TH. If it is I'll go through the drudgery of hornresp and try to figure it out on my own. If it's not suitable, I'll build the reflex box I am designing already.
TIA,
