Anyone with experience with the Troels Gravesens Ellipticor-3. A few years ago there was a thread about the Ellipticor-3, but it was a bit drowned in suggestions for all sorts of other speakers. I am interested in hearing experiences if you have built this speaker. I think it is exciting that Troels Gravesen has used a Sine-cap highpass filter for tweeter. It is quite unusual for Troels Gravesen, who is usually not afraid to use capacitors also on the rather expensive end. I watched a youtube Tech Talk 15 with Danny from GR Reseach. He had it in for an update for the XO as the owner was not really satisfied. Does anyone else have experience with the XO not working well or it can be thought that the owner just have looked at the chart and guessed at the values. I think that Troels Gravesen otherwise has a reputation for being a master at XO. Danny also says that cheap components have been used, something that Gravesen doesn't seem to have a reputation for either. The 2 of the coils are not only air coils but also of the Litz type which should be the level up from ordinary air coil.
From what I have seen, both Danny and Gravesen are extremely competent loudspeaker builders. As the Ellipticor tweeter is very effective, I have thought of using it in a construction once with a sine cap filter, which does require a lot resistance in the signal so that the impedance does not go all the way down. Hope there are some more experiences 2 years ago
where someone else asked about it. But it's not a cheap kit, even if you don't add capasitors in the XO as the drivers are some of the most expensive on the market.
Hope we have kept the thread on Ellipticor-3 🙂

Please don't forget it is both designers' job to sell loudspeaker kits, and parts, which helps feed themselves, family, and workforce etc.
A frequency response with the microphone on a particular bad axis can make nearly every loudspeaker look bad, also it is worth keeping an eye of graph axes scaling and resolution.
