My box build plans... will this work?

That looks like it will be okay but I would recommend closer to 20in² of port area per cube with that sub.

Why would you suggest that? I've done several boxes for Q's and BTL's and 12-14^2 has been more then enough. Q has a rather loose suspension, so I wouldn't do that much port area....

OP how much power do you have and what music do you mostly listen to?

Is this not the sub in question?

From the looks of the TS numbers, that's not a high compliance sub. Also, what is your benchmark for the claim; "more than enough"? Did you calculate port area before building? If so, what method/software did you use?

Did you build with less and more port area and then test the enclosures in controlled environments? If so, what were the results?

I see. What would be a better alternative?

winISD, its not the best of the best but its the best FREE downloadable box building software, lets you put the TS parameters of the sub in there and also shows you what the frequency response of the enclosure for the sub will be like in a graph. theres tutorials on youtube on how to use it.

It's also worth noting I did not add on the additional spider option. I listen to a lot of hip-hop, but not much of the modern stuff that bassheads listen to when showing their cars. So that's to say not quite so much emphasis on 30-40hz boosted synth basses. I listen to a lot of jazz and alt/prog/indie rock and metal too, a lot of stuff with drum and bass grooves. I'm tuning to around 30/31 so I obviously don't want a big spike and do want it to dig low and be pretty balanced.

And i've done big 3 and have an HC1400 under the hood but that's it. I was planning on giving the sub about 900/1k at full tilt

As long as you have some EQ to tame down the bottom end you should be happy....

So what would you suggest for internal cubes?

3.25 - 3.75 net is what I'd do. with 12^2 port per net cube

surely you're thinking of a 15 haha.. i have a 12.. so for 2.5 internal around 30 sq inches port? Does it matter how big width and height are just as long as it gets to that number?
