Hello all, thought I'd share my current project. I had some old magnevox speakers lying around, very old stuff and sounded quite poor (looking at the picture now I realize how funny that might sound). I've had a lot of parts lying around waiting to be used and figured I could save myself a bit of time building a new cabinet, and use the old junk magnevox. The exterior and construction of the cabinet are fine, so it just needed a new baffle.
A new baffle was cut from fairly cheap plywood I had lying around. It seemed to machine fine enough and I wanted to keep costs low on this one given the cabinets cheap chipboard.
I have a DX25 inside a WG300, and some Peerless 160f25pro01, wg adapters were printed by a friend for free. Next up is mostly waiting on PE to get back to me on a potentially bad measurement mic, hopefully things will be warm by then and I can get some nice measurements to start working on the crossover.
Not sure about keeping the cabinet ported or sealed, will have to see what this driver likes in winisd.

Got a little bit of amber shellac on the baffle to make my cheap ply look quite fancy.
I have them setup at the moment with reaper and Pro Q 3 handling filters, then into two aiyima a07's. I have to say they sound very good. This tweeter and waveguide combo is quite excellent. Low end is lacking of course but a sub helps. I'm honestly super impressed with the tweeters performance to the point that I'd like to just build new cabinets with less diffraction issues and a more appropriate volume for the woofer. There is quite a lot of vibration in these cabinets.
Any ideas on potentially better cabinet volume for this 160f woofer?
At the moment I'm deciding whether to build a resistor based impedance capture rig, or just buy DATS.

So I built up a cabinet that is basically the Cinetor EVO, going to see which one I prefer the sound of the tweeter in. I need to go buy a resistor and making an impedance measuring rig, but I did make a little lazy susan with marked angles that seems to be working well. Here's an indoor measurement set, I live right next to a highway and outdoor measurements just don't work for me. It all looks good aside from a dip at 15k, Doesn't quite look like Heismanns data but that's ok. I may need to further increase the depth of the adapters screw holes as the plate doesn't quite make flush contact with the waveguide. I have some material in between to seal it up. Overall it looks good to me, certainly much better than the dx25 by itself.
I was also curious, I'm getting weird behavior with how I'm doing tweeter measurements, I'll do 600-20,000 but vcad doesn't like that, just a straight flat line coming out of the bottom of the tweeter response that affects the overall response of the speaker.
I assume I would need to add a cap for filtering, anyone have a go to value for this?
