Have you tried different positions of the BB?
I originally that the black boxes were absorbers. I no longer believe this. In my room I believe they allow me to steer the bass where I want it to be. While tightening it in a very nice way.
Not yet, I’m thinking it may need to acclimate to the environment a little bit - the metal chassis was pretty cold when I unboxed it.
Right now it’s centered between my speakers with it’s back edge even with the speakers’ baffles.
After reading the Black Box thread, in fact that’s the reason why I ordered it, I didn’t know what to expect other than it does something to make systems sound better (at least different). SR does kind of market it like a bass trap but they don’t come out and call it a bass trap.
When you say you steer the bass, do you do it with one black box just based on where you put it?
I have been told by our local SR person that the BB would compliment the ASC tube traps that I have. The Cable Company folks indicated I should try the BB before the traps. Not sure what that means.
This is also my favorite position, you may find even more sonic differences simply by moving it (on the same center line) 10-20-30 inches closer to the listening position.
Corners on the front line and along the side wall are other recommended options (where I’ve honestly found the effect can range from imperceptible to subtle). It means that position matters, be patient.
Try also removing it from the room, you’d be surprised.
I’m curious to know your opinion on the AVAA cylinder and how it works combined with the BB cube. The “solids” in geometry and in the audiophile world, so to speak!
I moved the BB back about 2 feet so now it’s front edge is just behind the FR20s rear edges - I heard more of the effects I heard at first (I should have followed the virtually nonexistent instructions more closely because this is their “Primary” location in their diagram).
Thanks luca.pelliccioli, we were responding at the same time. I will try moving more forward also. My seating position relative to my speakers may be shorter than yours, mine is only 75".
Removing from the room is the first thing I did - several times. I wanted to make sure I was hearing what I thought I was hearing.
I’m getting hopeful, if the AVAA C214 absorbs enough of my room’s resonant frequencies below 40Hz and not interfere with, or be interfered by, the BB this may be a desirable solution.
Funny thing, I don’t expect the AVAA C214 to have the same effect as the BB on the rest of the sound but we will see.
Still no tracking info on the C214.
To explain better I offer the following. I am under the impression that there is a major Bass Null in my selected main seating position. I had two helpers when I went through a testing process. My friend who was sitting in the listening chair said that when we put the black box behind the listening chair he could now feel the bass in his chest. Behind the listening chair is a three seat theater chair. We put a black box behind the center theater chair and judged it to be a good thing. So I put two black boxes, centered three feet apart on the perpendicular bisector of the speaker location. That is where I have left them.
It seems to pull the bass through the location of the main listening chair and the secondary chair behind it. I did try putting one on the center line in front of the listening chair and one behind it. I judged this to be no improvement. The boxes in that setup bothered my bunny, my wife, and myself. So back behind the theater chairs, 3 feet apart they will stay.
I have no other tube traps of any sort in my room. I have a friend who once had his room nearly completely filled with tube traps, diffusers, sound clowns, and of course pictures of mom naked. I judged none of these items to help. (and I felt bad for mom)
Thanks for the info and the laugh!!!
My 6 year old 90lb German Sheppard likes to sing to the Tijuana Brass - Ladyfingers - when you hear what sounds like cat meows. Today, with the BB he starting singing as soon as Herb Albert started playing his trumpet and sung all the way through. Hopefully he doesn’t want to play with the BB, but I think he likes it.
There were no naked pictures.
Maybe not in your reality. ![]()
Talked with Edgar last night, mentioned the black boxes. “Throw them away they do nothing!”
Then he put some new software on one of my devices and oh oh oh oh my!
Someplace completely new.
Never been here before.
Wouldn’t have guessed this could be an option.
Measured response from in ear microphones.
The speakers literally vanish. No sign of them whatsoever. Frightening, but I’m getting used to it.
The cool thing is, you can fine tune your Spectral Entropy in multiple ways.
Some of you don’t know what that means.
I do now. It seems nice.
I love the fact that Steven will insist on missing out on this. That fills me with joy.
None for you Steven!
I woke up dreaming about calming curves with at 330 AM after chatting about it. Back to my dream solving nodes that don’t matter won’t at your ears when the BB is no where near the ear? ![]()
Now put on the b4mac headphones option and see if your speakers and headphones sound the same and headphones sound the same with or without ORC?
I will. But not soon.
You have it bad.

Did you find you operated the preamp at higher volume settings woth Bacch ORC given it is mostly taking away dB versus boosting.
I am hoping the ORC maintains my B&K curves my speakers were voiced to that took into account room gain instead of the flat line response curve. Though the speaker designer said initial XR290 images he had in anechoic chamber were startling. And much closer to his single full range driver line array IDS-25s he used EQ on ended up liking better and selling off the XR290s which are three ways in line array.
This will ne fun comparison to RoomPerfect that that is designed to preserve the curve of original speaker design as much as possible. But it is apparent the room is adding some collaboration stilll.
The ORC results in a 7.3 dB cut in volume. I do have to turn up a bit more now. But the result is much smaller adjustments over a wider range.
Thinking about this some more. Since creating filters is a two stp process. Would one have to compensate for volume on the second sweep? I guess I will figure that out by watching my big ble power meters and adjusting if they arenot at my optimal 12 watt room peaks.
