At least the weather is good…

Can some one explain this room sweep to me.
I am not understanding it. it looks very rolled
Off to my eye.
It seems like the ribbon panels are smoothing out on their own.
I am starting to see that graph in my sleep. lol. It is my own Rorschach test. It would be nice if you could superimpose those those graphs on one another. Just for those who claim there is no measurable difference during break in. Of course you would have to keep the other variables constant less they their way out.
Not really; Don -- who also visited seven days earlier -- found significant progress. I am hearing significant progress; I have trouble leaving the room.
I am not English but I will at least defend the beer...it's good.
Yes; thankfully.
This I cannot hear, but according to the curve the collapse at 20 Hz has also disappeared (and that is with a light touch on the woofer level).
I think the woofer towers on this thing are completely amazing. The base texture and resolution on Dave Brubeck "Take Five" definitely is better than I have ever heard in any of my systems before. Depth is more obvious than it ever was with the Prodigys plus REL Stentor III.
I think the four columns "disappear." (I am not suggesting you would agree.)
My drive to aim for high-power SET as an amplifier alternative has weakened.
At this time I cannot see the argument for adding sub-woofers.
I even have lost interest at the moment in further optimizing the speaker positioning.

Could you change the scale to linear to show the 1 - 20kHz response. It may reveal the dip at 2khz and fast roll off above 12khz more clearly.
Also, please remember that the pink noise is going through the amps and subject to their characteristic output curve rather than direct into the speaker and you are measuring the room sound and not the speaker.

Hi Ron,
Very glad to hear it. I am not so surprised that the woofers blend well as the crossover is pretty low and they are quite close together given the size of the columns.
I would say that the ribbon did break in somewhat (do you know how many hours you have now on them) and that could have led to smoothing in and of itself but could have also led to a shift in the resonance frequency that then better matched the filter design (my guess is the notch filter was developed on a well broken in driver).
I would be surprised if you need subwooefers and then you have a potential blending issue.
I think a high powered SET would still be interesting to try. I used a KR VA350i on my BG ribbons in a smallish room and it was plenty of power. Remember it is a line source and so drop off with distance is not nearly as sharp.
And makes one wonder why invitations would be forthcoming...A minor yet significant revision if I may
System sound criticisms are simply food for thought. They do not have to be adopted or worried about.
For our own systems only our vote matters.
