bandpass 12 xxx18 soundstream

[Marlo Stanfield]

I'd be more than willing to help ya man, just drop me a PM with specifically what you need help with... 12 18" SS XXXs + 6 XXX15000Ds + proper electrical in a properly built enclosure literally has almost boundless potential especially in a bassrace setting. As long as it's designed + built correctly some truly insane numbers have to come out of this thing. I know that the SS XXXs can handle a ton of power each, but 5-7k+ per each sub in bassrace is a lot for any sub.

With that much cone area I'd look into doing a huge bandpass(4th or 6th) or doing a build like the Sundown guys did with Flipsid's 12 18s build/Ascendant did with their 12 18s build. If you haven't seen them search on here and you should find both pretty easily, they each did a diamond with 3 18s on each side. Both up to this point have seemed to have very good results, can't wait to see what Flipsid + DJ's setups can really do @ SBN this year.
