So I've been wanting to wire up the auto-formers to a switch to make adjustments easier. I've also been meaning to add in some PIO caps, and a few other details. I just wired up the big mast_mutter autoformers to a nice, NOS RFT switch, though clearly 4 decks isn't needed, I had them on hand, and finding those in single deck isn't nearly as easy as I had hoped.
I've also wanted to try some Atlas Sound 100w autoformers as I've heard/read from a few sources that they're pretty decent, especially if just used for MF/HF. So I mounted those on the crossover breadboard as well, made some leads, and plan to compare them sometime this weekend.
I'm also taking down the big horns behind these. For a few reasons.
1 - I love these two ways that much. Though not the main reason.
2 - I'm about to start building some multi-cell mid horns. This will be a long, slow project I suspect.
At some point I want to try a few different crossover slopes, I think I need to roll the woofer off a bit more steeply, possibly. I'm hearing some 'congestion' around the crossover point (~2k), especially at a bit higher volumes. This could of course be the compression driver/horn, but I want to rule things out and a steeper slope on woofer, or CD/horn, or both, should help me do that.
I'm also still on the hunt for another EA 175, I have a very nice single, but haven't had luck as yet finding another.
The Soviet military KBG PIO capacitors sure do sound nice. I think I'll buy some larger values.
Cheers,
Gable
