I have a subwoofer that is already very old but of excellent quality from the Brazilian brand Selenium. I intend to build new boxes for them with new configurations and for that I bought another pair and I intend to make these new boxes in the ISOBARIC configuration. The model is the SELENIUM 10SW2 which I need the Thielle Small parameters which I have lost after all these years (they were manufactured in the 90's). If anyone has this information I would be very grateful if you could share it here.

Very grateful for the attention of friend Dantzig65. My first acoustic boxes were built with Selenium units in 1978. Certainly the best Brazilian brand. The woofers of that time were already made with an injected aluminum housing. Too bad the brand will disappear as it was bought by Harman Kardon/JBL, but this is a sign of its prestige in the Brazilian and world market. Thank God that didn't happen with Embraer. . .hahahaha.
