    Obsidian 15's enclosure size

    Im gonna be walling 4 15's in my roadmaster off about 1k rms a sub. Any one that has an back ground in the amount of air space they like ? Tuning will be 30-32 and it's just a groundpounder maybe I'll hit a meter sometime but I'm not going to be competing.

    Lol that was the first place I looked , but 2.5 to 3.75 is a pretty broad spectrum to work with. Being I'm gonna overpower a little I was thinking like around 3.25 but I'm thinking that may be a little much for the power I'm giving them. I'm mostly looking to build a budget low end hair trick monster.

    I was also going to recommend going with what they have on their site. I ran a 15 in about 3cf on 750 800watts and it did pretty well.

    I figure with rise they won't be getting a full 1k a piece anyway. I'll most likely go between 3 and 3.25 , if they over extend or heat up I'll back the amp off a little.

    3-3.75ft3 is my recommendation.


    If you are running 4 in a common chamber enclosure then you can use that to your advantage and use a slightly smaller enclosure

    Stick with what Pro Rabbit says. You are correct in the recommendations we have up offer a very broad range. We do that because technically the drivers will work in all of those enclosure sizes. However, there is a sweet spot. In our opinion the sweet spot for the 15's is between 3.25 and 3.5 ft^3 each and tune between 30 and 32 Hz.
