F4, I have most all parts. But gain diff with the J Zen will be huge. So targeting something that’ll coax both driving these and being a multipurpose amp in the long run.
soon stock is ready for 6 deep Ba-3, or BBA-3…

On 5/31/2020 wg45 sent me the info on the SLOB v2.0, my one and only woodworking project was a pair of sealed enclosures for Utah 8" drivers. The plans were included with the drivers, I made them in high school shop class several lifetimes ago. Since I don't own the necessary tools/equipment nor have the skills for this project, a neighbor was kind enough to help (he did all the skilled work, I sanded, glued and cleaned up).
I used Eminence 4015 ULF woofers and Cube FC-8 FR drivers, so here are some pictures.

What is the sound impression of these speakers with Cube FR?
Are high frequencies "good enough"?
What about blending with woofer?
I have not read the thread in details and don't know the data sheet of Cubes to have an idea of optimal crossover frequency?
Is this version of the slot loaded OB considered a "little brother" of the other version that has the slot horizontal with with a number of smaller woofers?

1 - Have not had enough time to listen to them yet, still have Lowther PM2A's in main system. I'm waiting until after BAF 2022 to learn about measuring speakers.
2 - Sounded good to me the little I listened to them.
3 - I built a 6-24 active crossover for these speakers, could take me most of the winter to "dial" them in.
4 - I'm using 150Hz as the crossover frequency, not sure if anyone else used the Cube's. The Speaker camp used Moth FR drivers, living in Wisconsin limits my participation attending the west coast events.
5 - The thread is called SLOB v2, so that's what I call them.
edit, bad spelling
Not only does BAF 2022 have a presentation about measuring speakers, the US distributor for Cube speakers will be presenting info on the Cube speakers. I'm going to ZOOM it, a bargain for $30.
The one I was thinking about is this one with vertical slot:

This is probably v1 and v2 a further development?
V2 seem more simple to built. I was impressed by the v1 low end measurement as it goes quite deep. Even at 20 Hz there is some "output".
V1 could probably also work the the Cube but if V2 has same performance it is easier to built. The baffle of v1 looks larger than v2 and this could make a difference for the low end.
Wonder if Nelson is still using his L300.......just to be totally off topic 🙂
Think many would like a pair of those.....

Hello wg45,
here we are a year later…how do you like the sound of the slob2? Also, on your marked up schemo above you are showing the original lx-mini, correct? I was looking at the camp slob2 2022 schemo & the values are a tad different. Just wanted to get my head around your thoughts after time gone by. Thanks for any feedback.
Brian in Seattle.
I just have to say…it sure is fun for me learning from all you Electronic heads out there…you all make it worthwhile to try new stuff. One thing I’ve found are my rooms are getting smaller!!
Looking at volume pots for lx-mini…I have zero experience with which element type is considered “quietest”…plastic, cermet, or wire wound?? Appreciate the input.
I bought conductive plastic.
