akuma4u Posted December 10, 2019 Report Share Posted December 10, 2019 Hey i got a buddy selling obsidian audio oa 12s d4s for cheap. He says they are basically sundown sa12s. The com0any went out of biz years ago so hard to find info on them. they are d4 subs. They are rated for 600rms but can take considerably more. I was able to find ts params on d2s. I want to run 2 in a sealed box off 2000rms. What i need to know is what would the f3 (how low the box will play before losing 3db) be in a sealed box. If its too high i wont bother. The box will be about 2.8 net here are the ts params for the d2s..can someone pls help me out and find of the f3 in a sealed box for dual d2s? Thanks! Product: 1 Obsidian Audio OA-12 Dual 2ohm 2.

CstrokerV Posted December 10, 2019 Report Share Posted December 10, 2019 They are not basically SAs they had weak motors if I remember right. And if I recall only way to get f3 is to actually measure the subs in a box my build http://www.stevemeadedesigns.com/board/topic/142505-small-build-log-4-dc-lvl3-10s-tl-update-link-to-rebuild/ http://www.stevemeadedesigns.com/board/topic/154258-rebuild-6-lvl3-12s-update-small-video-nothing-spectacular/ new build http://www.stevemeadedesigns.com/board/topic/188181-03-trailblazer-slow-build-8-dc-lvl3-12-m1-motor-m2-parts/ Link to comment Share on other sites More sharing options...
