Hello guys. I was told to come here for getting a box design from some members of other forums. Anyway, I'm looking to do a rear loading horn for a single Sound Splinter 12" RL-p. But, I have never designed one, nor do I know who to go to for plans. So, van anyone here make some up for me? Or point me were to go for some plans. (cash can be added to if need be) thanks.
