Hello all,
I am currently working on a 2 way speaker design and I have posted about it previously on here. It started as a 3 way design but got bumped down to 2 for the sake of size and complexity as there is a ton to learn. At the current stage, I selected a tweeter and a full range "woofer", as well as a 2x amp, and then a power supply for the amp, and a power supply for the analog crossover. Based on the datasheets, I plan on making my xo frequency 1500 hz.
Driver Datasheets:
Tweeter: https://www.parts-express.com/pedocs/specs/275-051--dayton-audio-nd25fw-4-spec-sheet.pdf
Woofer: https://www.parts-express.com/pedocs/specs/264-1088--tymphany-sds-p830657-spec-sheet.pdf
Here is my component list at this time:
Drivers
Amps
Power Supplies
I am now a bit stuck in what is the best way to proceed forward. Originally I thought the best idea would be to work on the crossover design and follow this paper I found By TI about 2-way analog xo design: https://www.ti.com/lit/ug/tidu035/tidu035.pdf?ts=1734384619091, but it seems that to do that I need to generate some dB/f graphs of my uncorrected drivers in order to design the filter and xo components in TI FilterPro. I also downloaded and checked out VituixCAD. Looks like I can simulate and do xo in there, but I will still need frequency response data, and I haven't found a comprehensive guide as in depth as the TI document for using that program. Then there is the enclosure as well... Does anyone have any recommendations on how people have done this previously or where it would make sense to start? Please let me know, I am on winter break right now and am eager to be working on this, but maaan is it a lot more complex than I initially thought!
Happy holidays
