All right, I built a new bass horn. Ever heard of a Jamboree, but this is what i will be using. I started to play around with some of this but my laptop crashed. So know I need to find a way to get my pc to work. But I will look at this Holmimpulse again. Along with some other. I will say just but setting the crossover at 600hz between the EV horn and the Jamboree it sounds really good. I cant wait to get this whole system up and running, I just need to build one more bass bin, and find a smoking deal on a Mc2505 or just finish my Firstwatt F5 clones.
