In history Platon was there before Aristoteles. Actually, Platon was his teacher. For me closed box designs were also there before dipoles and I consider closed boxes the older teachings.
Platon is a fully active closed box with omni directional behavior over a wide frequency range. It is obvious that this speaker was inspired by the Linkwitz Pluto. The picture shows the test balloon that I have put together to compare it to Aristoteles. So far I can tell that the Peerless 2" FR does a good job and I plan to keep it. The choice for the mid-woofer has now been made. It will be the L16RN-SL (H1480). Especially when used without sub woofer(s), it is still the best driver for this application and a very nice unit indeed. Even much more expensive drivers are not so well suited.
The audible impression is very believable but with less depth of the sound stage compared to Aristoteles. It is planned to design a sub woofer for it.
Primary Design Goals:
- Smooth transition from omni to forward firing behavior (compared to Pluto the directivity index will rise above 17KHz because the Peerless actually reaches that far. But only on axis).
Status of the project:
- 11-Jun-2011: Comparison between Peerless and Aurasound driver of Pluto conducted (see measurement section).
