John Heisz - Speakers and Audio Projects | Designing Crossovers and Measurements / Listening @IBuildIt | Uploaded 1 year ago | Updated 12 hours ago
I started with a rough 2nd order crossover at 3500Hz and refined it from there. My first measurement showed a bit of peaking in the midwoofer response around 3800Hz, so I changed the filter on that driver to a 3rd order and lowered it to around 3000Hz. I then adjusted the 2nd order filter on the tweeter to that lower frequency and arrived at a pretty good response. I may do some more fine adjustments, but this is a very good start.
I also tried a first order crossover on both just to see how that looks. Again, it let in a bit too much of the peaking in the midwoofer response, so I ruled it out.
As for how it sounds, it's early yet, but I'd say it's very good. The midrange sounds clear and smooth and blends seamlessly with the tweeter. Lower midrange sounds full and neutal. I played a couple of songs (in mono) that I'm very familiar with to judge. Unfortunately, I can't record those in a published video, since that would be copyright infringement.
Next step is to make the solid wood baffles for both speakers and that will be the subject of the next video.
This is part 2 in my series on designing making a pair of open baffle 2-way speakers to use as "surround" speakers in my listening room.
I've created a playlist with all of the videos: youtube.com/playlist?list=PLQl9KPrpiIH-5l4QhxUYXHGhr-covK8n6
