    first box help! 2 sa-15's in a ported box

    I'm new to the forums, so hi everyone.

    I currently have 2 12inch kicker cvrs in a prefab box from them. But i want better and louder subs. After reading the forums i decided with 2 sa-15's but if you recommend something else im open to other ideas.

    This is the first box i designed how does it sound? 35x21x19 for about 6.6cu ft of air ..then a slotted port 2x15x8 for about a 32hz tune

    also i have no idea how to build the box so if you have any technics im open to here them! thanks in advance

    enclosure is to small. You need to have around 6ft after all displacements.

    I would suggest buying a design from some one or having an enclosure built to your application. Both options do cost money, but it will get you 100% the results you want.


    Designs are cheaper, and if you have the tools and time this is a good option

    Having one built costs more, and shipping on larger enclosures is high. However, you just toss it in and go.

    You need a much bigger port.

    SAs are light years beyond CVRs. CVRs are still my favorite budget sub though.

    Yep, CVR and SA are different all around subs in every way. Just do not put SA subs in a prefab enclosure. Just a waste of funds for the most part.

    in the optimal enclosure, in most cases yes.

    What kind of power do you have?
