The Tymphany/Peerless parts catalog is within close reach to me so this is based on a PLS-75 variant and our DX20 tweeter (distant cousin of the BeoLab 5 tweet). Largely, this config fits within the existing Penta baffle component dimensions.
Of course this eliminates the need to refoam the original midrange transducers and by selecting new mids that have rubber surrounds, it prevents the same problem from happening again. Secondarily there is an opportunity to improve the performance of the Penta as well given how modern transducers have come such a long way thanks to simulation and modern material science.
Let me know what you think! Anyone interested in a new twee-mid kit? Let's open source the Penta!
