[QUOTE="Art Welter, post: 82900, member: 52"] Re: 2" exit "line array" horn lens? Evan, If you are going to DIY, you may want to think about using a Paraline coupler on a 90 degree waveguide. You can easily go three way and still have good sounding mids. The Paraline is a bit tricky to make, but the waveguide is just two pieces of plywood at 90 degrees, the horizontal dispersion is great out to 16 K. The response below is using an EV DH1AMT, a 1.5" exit 3" diaphragm driver on a horn that fits in a 26.5" x 15 x 11.25 box . As you can see, it has response usable to around 250 Hz. I end up with an acoustical crossover around 680 Hz between the 8" and HF drivers in my PA. [/QUOTE]
