I bought a smaller band pass subwoofer at a flee market experimented with it but decided I did not like it. It was to much like a "one hit wonder" made only certain lower frequencies loud and left out others. I ended up taking it apart and salvaging the amplifier and power supply. The graph your displaying is much better however.
Thanks Jim for watching. If you listened over headphones or a decent sound system, it's pretty representative of the sound, but with the basement more heavily damped than the old room, I tend to turn up the volume higher and not entirely sure how it came across on UA-cam. Whew... All that to say that I never knew what a bandpass subwoofer was until I saw those on eBay. They were "Energy", a model I never knew existed. Checked out bandpass info online and apparently they're a pain to design correctly, but I felt if any speaker company could pull it off, they could. Never having heard them I wasn't impressed at first, because they didn't seem to do all that much... But wow, the more I listened, the more I liked them. The full range Energy speakers I was using in that video are quite nice, but they are super bassy. What surprised me was that with the subs running, they sounded even cleaner, like the bandpass added more depth and clarity to the mid-bass while also giving the system that sub rumble... Which isn't a rumble, but I think you know what I mean. That low, low fullness that makes it more 3 dimensional. I guess those were from the 1980's. They look like brand new. I'm going to do a video where I open one up to check the condition of the drivers. I don't hear anything funky though, they sound pretty clean unless I go nuts with the volume. They've only got 6-1/2" drivers in there and they're relatively small and lightweight. Having the subs in stereo is quite an experience. It really shows me how much stereo separation I'm lacking when running the LFE sub out. Being a passive design, I got lucky bi-amping them with the Energy 4.1e speakers because they're close to being the same efficiency. I'm using them upstairs in my work office now, paired with the little Yamaha stereo receiver and my Energy 3.1e's and they sound really nice. Very musical. Zero port noise which tells me Energy probably spent some time tuning them. Pretty cool speakers! I'm not sure they'd be able to make a difference with the big Jensen's, but for the rest of the speakers that aren't quite subsonic, they're a really nice supplement and definitely better than just a mono or dual coil sub. The stereo part in combination with being able to cover from the 20's to almost 300 Hz adds some life to the sound that isn't possible with a regular sub. I'm a fan so far, but these are 6th order, one of the hardest to design, but Energy did a decent job. I'll bet if plate amps hadn't come along, they may have carried them longer. They seem rather rare.
So spooky cool I love this fun vid Unc! Awesome job 😄👍
Thanks!

That track at 9:56. It's nice.
The intro scared me.
