I've got the old master kit hanging out, but the 24 dB/octave modules only go down to 50Hz in pre-built. I do have blanks available, and according to the document I'll link below momentarily, you'll need to solder in 8 470KΩ resistors to get 15Hz. There's also a formula on the document you can use to achieve a lower frequency is 15 isn't low enough for you.

Wow, sleeves... I didn't think this post would go anywhere! Now that I look (and confirmed by @Nemisis87), you're right: The PFM subsonic module is a 14-pin DIP header (18db/octave).

I have a soldering iron (newly purchased). I'm not great at it, but I might try my hand at fashioning one.

Thanks for the reply!

Darn, I just gave away a bunch of these! Hit up @buffalobill989 to see if he’ll send you one or two chips.

You can also buy them from Mouser. The PFM uses 18dB high pass, 7 resistors/14 pins and not 8/16 like the 24dB high/low crossover.

Thanks for weighing in, Nemesis. I've never heard of Mouser, but I'm checking out their site now. They have all kinds of goodies!

I might send a message to buffalobill. Thanks for the tips!

Not sure what you will need. If I have it and won't need it. I would be happy to send it to you. We still have a few weeks of sprint car racing left before we can spend time to install. Hell we've had the box pieces cut for 2 weeks and still need to put it together. Let me know what you need and I'll see what I have.

Hey, Bill... super kind of you to chime in. I'm was looking for the 14-pin DIN header and transistors for 15 Hz (470 kOhm) or 20 Hz (360 kOhm). Didn't know if anyone had any lying around...

Good luck on your install!
