Building stands for Harbeth 40.2's

I talked with my builder today. I told them I would reach out for more expert opinions on a final design.

Since the TonTragers are the benchmark for Harbeth stands, I'm trying to match them as much as possible.

Question 1- The TonTragers have a 1 inch riser in each corner of the top of the stand. Is this critical for optimal sound ? Or would it be sufficient for the speaker to sit flat on the top of the stand ?

Question 2- Obviously the top needs to be open except for the exterior frame, but can the base be a solid flat piece of wood...or should that be open also ?

Please chime in with any ideas...also I plan on using some good cone spikes on the bottom.

I've attached a pic of the TonTrager for reference for the above questions.

Thanks in advance.

I have the TonTrager stands for my Harbeth HL5. If you want to do a true clone the bottom should be open with no spikes! The one inch risers should be on the bottom the same as on the top!

TonTraeger stands

I have the 30.2XD’s

Resonance dissipation and decoupling:
Extended tenons -  top AND bottom - allow direct absorption of cabinet resonances and decouple the speaker from the ground.

the extended tenons on top of mine have routered out oval “dimples” in the extended tenons - “tone beds” are explained below ,,,, the tenons are not flat …It matters too,

I know that the 40.2’s have the extended tenons too, and it appears that they also have the routered out “dimpled “ tone beds in their model extended tenons.

Extended Tenons

  • The frames of the audio boards are joined with a mortise and tenon joint.
  • The so-called "extended tenons" are evolved out of the wood connection to form the four contact points for the speaker.
  • The upper tenons absorb cabinet resonances.
  • The lower tenons serve to decouple external influences.
  • The "extended tenons" replace the use of spikes.

ToneBed

  • An oval hollow on top of the tenons ( routered out) reduces the contact surface to achieve maximum form fit.
  • The ToneBeds prevent vibration bridges.

 

I would not chintz it …if it’s too much for you, then give it up , step down, and chooses a larger mass speaker stand & save the $$
