But this is the first time I have heard of stacking 3 pairs of Quads.
Why stop there ?

It was only when my brain kept telling me the bass did not go low enough and that the high frequencies were rolled off.
My rooms are adjacent to one another. I can have the same music material running at the same time for fun. There are matrix 800’s in the adjacent room. I can tell you and so can others that there is no roll off in the HF’s with the RM10 and 100% functional Quads. The room treatments between the two rooms is also very different.
Now the bass.

Interview with Peter Walker
Interviewer : For people who would like to use your speakers as mid-range and high-end reproducers - do you make suggestions about what they might add for moving- coil supplement below 100Hz, say?
PW: We try to keep out of it. Two or three people have made good attempts at this, adding woofers. It’s not that easy to do. Initially it’s quite impressive, but to try to give this a homogenous sound is difficult. Another thing people do is to use two of our panels, one above the other. This is quite reasonable because it is really a strip source, you can extend the strip source without deteriorating anything. All you do is add 6dB at the bottom end and 3dB everywhere else. It gives you a louder sound, a more impressive sound. That’s all right. Adding woofers has never been very good.
*****************************************
So it gives you 6 db more in the low end, and 3 db everywhere else. So it is not linear, and they still don’t play any lower than 45 hz .
Peter Walker never heard today’s subwoofers.
I had one occasion to hear stacked quads. Whether the setup or one of the panels was off a little, the magic I hear with two was lost. Seemed like a lot of effort and risk (multiple panels) _ to me at the time and the reason I pursued the sub route for db levels in the larger room. The secret for me in my space - to have the single pair panels elevated so they are 44 inches off the ground at the mid panel point. .

@Kalali
there is no such thing as a good deal with Quads. I would never buy any without seeing. and hearing them, along with the paperwork for when they were restored. Also removing the back panel to determine if they were a smoker. Would you buy a car that was owned by a smoker ?
