3 way crossover design software1/4/2023 ![]() ![]() ![]() Next step is to refine the measurement setup like pillows on the floor, making the transition from mic to PVC pipe seamless, better positioning of overall setup, etc etc. Now, I am having some confidence with more measurements and finalizing box shape for building it. As of now, I am very happy with this preliminary attempt where I have been able to capture the horizontal off axis behavior of a waveguide to some extent. The dimensions are similar to the intended final widths and final look of the baffle (at least the top half of it). I made the baffle out of insulation foam material and carved the angular shapes/chamfers on the baffle out of it using pen knives. Here are some pics of temporary baffle, measurements and resulting frequency response measurements, over 50 degree angle (0 to 50 degree or 10 to 60 degree, I lost one of the measurements, not sure which one). However, as per the advice I received in other forums to move to a measurement based design and stop wasting time using traced SPLs, I have slowly built up a setup to take measurements using ESI U86XT audio interface and a Dayton EMM-6 measurement mic.Īs a first attempt, I have made a prototype of the top half of the intended baffle and started studying taking actual measurements using REW. The VituixCAD six pack showing resultant system response details is also attached. With my limited knowledge, I designed a crossover for this system as shown in attached image. The woofer is assumed to be put in sealed box of size 55L, midrange also in a sealed enclosure of about 12 L). The simulations that I have attached along with this post have these drivers placed on a baffle of width 32cm and height 105 cm (with 20mm edge rounding for easing diffraction-related anomalies. ![]() ![]() I started with generating a crossover configuration based on traced SPLs of these drivers from their datasheets (Now I know that ideally, we should put the drivers in the intended cabinet and then take measurements and then design crossover based on it). I have selected the following drivers for this project (I have these drivers with me):ģ) SB26CDC-C004 as the tweeter in a 4 inch elliptical waveguide by FM augerpro. I want to study and design a DSP-based 3 way speaker using VituixCAD for crossover design. Finally, I have gathered the courage to make a post here. I have been very inspired by the projects here. I have been reading and learning from posts in this forum for quite some time now but have not interacted much due to my limited knowledge and the very high standards that I see in all speaker projects posted here. ![]()
