Hello, I'm not really new here I was very active user in 2010ish (bsnow)(bsnow72). In mid 2011 I purchased a pair of planetaudio big bang bb215d, moved a couple of times these subs never seen power yet. I cannot seem to find the manual. Seems to me I recall them wanting 2.5 cubes tuned at 31hz. So 5cubes.
I built my box 10cubes after port dimensions. Tuned to 32hz. The reason for such a big box is so i can go 18" later.
My question is 10 cube WAY to big. Seems to me the recommended 2.5 is kind of a small box.
Be powered by a sundown scv3000 I'll set RMS to 2000Watts.
Thank you sorry for the long post.

HI dYohn, glad to see you are stil active. Yes I saw that and ty. That calls for 2.2 cubed box with a 23" round port by 11" long. Think they were drunk when they wrote that.lol. What about just opinions. I've have these for 6yrs bout time to use them. I can always add filler to lower the cubes
And hello to stevedart if he's still around..
