Yeah they are sheep wool filled too, I posted the link to them earlier. They have an alpha of 0,6 at 63 Hz, so not too bad.Actually, I commented before seeing your photos. Those traps look thicker than what I meant by "typical bass traps", and they probably remain effective a little lower.
I also have the sub active again, in manual mode, centered on the front wall. Much more bass than without it...I like it
