Footers for heavy speakers

On the other hand, Stack Audio Auva 100 are getting very positive reviews and are $1,200 for the set of 8
I will be careful about footing your dual FLH type speakers, you might lose the midbass. You might initially think it is clean or something. Just be careful
Hello
The best feet are to my experience HARMONIX TU210 ZXM + RF999a+ base if your room has a thin carpet or wooden floor. If you have concrete hard floor, best is TU-210 ZXM + RF-999Z base.
I tested many feet in ball bearings system for Stillpoint to Cerabase, Jim (discontinued) and none are on par with the Japanese cones. The 2 other solutions are PRANAWIRE DanTien, certainly the best but quite expensive at 9000 USD/set of 4, and the new ALSYVOX O2 feet that will put the famed planars to another level. Introduction in May at MUNICH High end show. ALSYVOX design is proprietary and custom tuned for planars.

Agree
I’m happy with it now
I might try Auva b/w the bass cabinet and the multicell horn
$300/each

Spot on comment. In that case (losing midbass or enjoyment) I recommend adding Harmonix RF-999 spike bases.
Yes, that's right but I precise RF-999Z is better for system which need bass control and very hard floor like stone or ceramic. The other model RF-999@+ could be better, more open but 1) if you have a hard wood floor like my audio room and 2) if you have HARMONIX cones.
For audiophiles who put HARMONIX base under speakers stock cones or spikes, use of RF-999Z is recommended (98% of stock spikes or cones do not work, they do not act like mechanical diode).
To be clear, RF-999 or RF-999 MKII are very old models and were much less neutral and alive than new RF-999Z/999a+. The old models sound recessed and warm with less definition.

In any case the bass is much less of an issue now since I’ve made a few changes under DDK’s guidance who was over at my place recently. Different listening position, removing SRA VR from under the linestage, etc.
It seems the more I remove from the system the better it sounds.

i wouldn’t, because the dual FLH couple better to the floor. Let the floor be an open baffle for the front horn to fire
If you remove things and get better sound it's because you remove damping accessories (SRA platforms are as many others) or accessories that give a bright sound, a colored sound. There are so many accessories that change the sound but do not improve it and mostly degrade it. I also see that you use cable lifters with wood (a lot of damping too). Less is more is not a rule..
You use tubes electronics, all these kind of amplification is very sensitive about micro vibrations, even if some manufacturers use decoupling system inside. Testing a set of 4 HARMONIX cones (TU210 ZXM best, REI-168 or RS-777) + RF999Z bases could be interesting.

ALSYVOX had previously balls bearing system with synthetic ball. This was a very clever system to prevent vibration to affect aluminium ribbons. However ALSYVOX tried same concept but differently designed and the new O2 feet are really a huge improvement is clarity, definition, inner resolution. Trebles are more natural and bass is purer with more nuances.
I do not tied Townsend platform, but based on my experience (engineer in mechanical vibrations) spring systems are only good to isolate from massive floor vibrations. Cones or ball bearing system like O2, also drain vibrations from the component. This approach was discovered (or pushed at the best) around 1980 in France by Vecteur, a brand of Turntable (discontinued). I also consider cones and base as the best isolation system for Alsyvox external filters, but some test are done to try O2 feet. The problem is that most ball bearing systems ring and know only 2 that do not ring, O2 is one of them.
