[QUOTE="Norval, post: 41090, member: 62"] One of my very first speaker designs I did myself was with some 6" Infinity drivers (not Infinity Dynamics), and I can't remember if I used the cheapish Sabas tweeter on it or a JBL titanium dome. I had no way to test frequency response at the time, and did the TS measurements with a tone generator, multimeter, and calculator. Used the Bullock on Boxes book as a guide. I opted for a 2nd order LR filter at 2500 Hz, and once again calculated with a calculator, used Zobel filter to make sure the Z is correct, and had little knowledge further to make sure the cutoff is at the right frequency. The project turned out quite good, and even today after noch more experience and exposure to better systems, they don't sound bad. Though the Infinity drivers are good, they were actually quite cheap. My first design using better drivers was with the Seas P17REX, at 3 x the price, and although easy to work with and and good drivers, it took much more effort to get a sound out of them that I liked. So yeah, sometimes these cheaper drivers can suprise us. [/QUOTE]
