Woofers getting workout, but no bass

Wow, this two year old thread is what I am experiencing right now

I also have woofer pumping to a great degree

Triplaner arm, zyx cartridge

I have records which don't appear warped but have slight air gaps between the record and the platter as the table spins (coupling issues?)

I also have a Doshi preamp which rolls off at a very low freq. There is the option to change out the capacitors on the phono pre although Nick feels it affects slightly higher freqencies.

Mine isn't positioning - passed the placed the needle on the non spinning record test.

Placed a nickel on the headshell and couldn't tame arm / cartridge resonance.

May try a TT periphery clap, but not sure it would fit in between my platter and triplaner. Also the risk of breaking a Universe may be too much to try.

My Salk Soundscape 10s go down to 22 hz at 1.5 dB down. Is there really usable music down there outside of Saint Saens Organ Symphony #3 ( not HT )?

Seems to be robbing a bit of my amp power left for musical dynamics

The cartridge and arm are known to work very well together.
Starting to lean towards rolling the doshi off higher.
Any other suggestions?

Yes - a rumble filter I recommended in the last post before you revived the thread. At this level of playback and setup, if you're still experiencing woofer pumping, I'm not sure what else you can explore to address it. Perhaps moving your turntable from between the speakers if the room allows it, but I'd suggest trying the KAB, which I found very transparent and incredibly effective.

I think doing a capacitor change in the phono stage to roll off the lowest freq would accomplish what the KAB would do without all the extra hardware and interconnects.

Why did manufactures get away from subsonic filters?

purity of corrupted sound

bass works fine in my setting, just crazy woofer movement

You might play with the way your counterbalance is set up. The Triplanar has a multiple weight system and you can use that to affect the effective mass of the arm and cartridge.

If the effective mass is off, the setup might be susceptible to warp and the like. I have the same arm and cartridge, with no problems and no rumble filter.

We have the large weight and one of the smaller ones (about 3/8" thick) set fairly close together to get our tracking pressure. The amps and preamp have bandwidth to 2Hz no problem, but no problem with woofer pumping either, even with some pretty warped records.
