Is this why my analog rig isn't so hot?

harmonics of different fundamental frecuencies.

Yourmama,
I forgot to remark about one of your points: some Teres tables include acrylic and some don't. Mine doesn't. Check my system.

Doug,

I guess I need to clarify my 60hz-70hz comment, I know the B&W published specs, but that's not the same as true bass. Of all the speakers that I know I can only think of a couple which can do even 40hz of real bass. As Raul so nicely explained, bass is extremely difficult to reproduce and it has all to do with physics. You need volume to reproduce bass and most speakers are too small to do that, only something the size of a Wilson Grand Slamm can start to approach 40hz bass, that's if your room can support it. Low bass is going to be a bitch, the best sub 40hz bass I've heard was from giant horns of 7-8 meters long, even then there was precious little below 25hz. I'm not counting fundamental frequencies, just true bass. I'm sure you've seen a pipe organ or two in churches, please note the size of the pipes that reproduce the low notes!

Raul- You mentioned subwoofers that could reproduce proper low bass, what have you heard?

Mama

Dear Raul,
Which harmonic of a 16Hz test tone is lower than the 32Hz organ tone at the beginning of 'Zarathustra', which we hear quite easily?

On the HFN lateral resonance track Paul and I both hear pitch-differentiated test tones at 24, 22, 20, 18 and 16Hz. On the vertical resonance track we hear and distinguish 25, 23, 21, 19 and 17 Hz. I do not claim our system can reproduce these tones with flat frequency response. But reproduce them it can and does.

This is the physical reality on our rig in our home, which you admit you've never heard. When theories don't explain observed realities then it's time to revise the theories. I am fully aware that this process can be uncomfortable.

You have often urged me to listen before passing judgement. That was good advice.

Regards,
Doug

Dear Yourmama: Bag-End ( I can't remember the model ),a pair of Velodyne HGS-15 and a pair of HGS-18.
Regards and enjoy the music.
Raul.
