" Key parts include a 0.75" horn-loaded textile-dome tweeter from Denmark's Vifa and a 7" SEAS paper woofer from Norway, both made to DeVore's specifications. John is always tight-lipped regarding his crossover designs (and crossover points), but he will yack copiously about the tweeter and woofer implementation.

"Design and Description
John told me that for the O/Baby speakers, he tried an array of three 8-inch and three 6.5-inch drivers, all based on the original Orangutan recipe. He used the same type of paper, motor structure, and the same ideas behind keeping the impedance smooth and relatively high. John ended up going with the 6.5-inch drivers that use neither a Whizzer nor a phase plug in the cone. The bass driver has a single rear port and goes down to about 40Hz/."https://theaudiobeatnik.com/devore-fidelity-orangutan-o-baby-speakers-review/
