    Enclosure help for Obsidian 12's Foam Surround 8 layer aluminum SPL coils

    Just picked up these subs. Just looking for ideas about enclosure and maximizing output. This is one of the 3 pair built by Obsidian for SBN.

    The problem is its different than regular Obsidians. The pair were built by Obsidian to be used in their CRX at SBN. They built 3 pair and only used one. I have one of the pairs that they never used. They have 8 layer aluminum voice coils and foam surround. They designed the soft parts to be really light.

    I am hoping someone that builds subs will have an idea. They have a pretty good idea based off the lighter soft parts.

    No they would need to know far more specifics but I bet they added some pretty stiff spiders to help get the fs up and take some power

    If they are softer then standard then they will like smaller enclosures. However if ircc they did use stiffer spiders which would mean you would want a tad larger enclosure then normal.

    They used quite a few stiff spiders super fat coil and not sure what else what all specs it changed for sure are up in the air.
