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 appreciate your comment …. I guess that NO speaker is decoupled from their speaker stands .

If I highlight below the TT narrative explaining the purpose of extended tenons in my prior post, maybe that is a better synopsis for the readers. (Y/N)?

  • The upper tenons absorb cabinet resonances.
  • The lower tenons serve to decouple external influences

Thank you. To be clear, I was happy with the TonTragers, and do believe that they are well-designed to compliment Harbeth speakers. My pedantry stems primarily from my experiences with isolation devices under speakers, which, when properly designed, do decouple the speakers from the floor. And yes, in my view, and more than a few others, the difference is meaningful.

Interestingly, I engaged in a related experiment with my 30.1/TonTrager combo before I moved on to my current system. I was able to purchase a discounted pair of Townsend Podiums, and tried them. The Podiums are considered by some to be the best of the various speaker isolation options, albeit at a steep price.

Well, my experience was not good, but I do not blame the Townsend product at all. In my view, it was the lack of hard coupling between the 30.1 and TonTragers that caused the failed experiment. Also, consider that there can be a perceived lack of bass impact with such decoupling, and given that the bass of the 30.1 is limited to begin with, that was in issue.

For further perspective, I tried – and kept – Isoacoustic Gaias under my FinkTeam KIM speakers, and consider the improvement to be substantial. The Gaias are probably the most widely used speaker isolation devices, and some high-end companies now supply them as standard equipment.

Note that I am not arguing that the Gaias are in some way superior to the Townsend Podiums (except in terms of value). But my KIMs, which are also stand-mounted, are hard-coupled, and as the stands are metal, the Gais can be screwed directly into them, providing further, crucial hard-coupling.

Finally, as you pointed out above, the BBC type speakers are designed to resonate, so even if hard-coupling could be achieved, I am not certain to what extent they would benefit from feet that are designed to both isolate and provide vibration control.

@yogiboy

you are right. My apologies. What was I thinking. 

Entering my opinion about looks on an anonymous forum?

Here is a constructive angle: if you are to build stands that you will look at all day, make them pretty.
