12BTL ported or 2x12" Q's sealed.

I have not really got a direct answer yet, so figured I would post here.

Would 2x12" Q's in a sealed enclosure move more air than a 12BTL ported?

I prefer low bass ~30Hz.

So far, I like how deep my 12BTL gets, I don't want to lose any of that.

I haven't heard many systems, so I need to ask alot of questions sometimes..lol

I would think the ported BTL would be louder if thats what you mean by move air.

How much power are you using?

If It was me, I would build a ported enclosure to opt. specs for the BTL, tuned to ~29hz.

How much volume(space) do you have in your vehicle for an enclosure?

I have 4.0cuft available to fit a box in through the trunk opening. Before any displacements.

Right now 12BTL is in 2.8cuft tuned to 29Hz. 45sqin of port.

I have another box, 2.25cuft @ 32hz. With 32sqin of port.

And noticed in felt like it moved more air, at least it moved my mirrors alot more.

My current box hits the lows smoother, so just kept it in.

The BTL in a properly aligned setup should move some serious air! Bump up your tuning to around 33hz and it will be intense on the low and upper bass frequencies. Most rap and hip hop is in the 35-40 hz range.

You are NOT a Q buyer.

You are NOT a Q buyer.

For the hell of it, I plugged up the port with towels, and yeah, the low frequency intensity definitely died.

I thought that perhaps the larger port on the new box decreased the air velocity, which therefore made it seem that the moving air wasn't as forceful.

Make sense?

Or is it because of the lower tuning?

If I want to make another box to slam the lows more, what sort of enclosure would be best?

Less port area?

Current box is 2.8cuft after displacement with 45sqin of port at 41.5" long, ~30Hz.

Maybe build a box with less port area and shorter port, tuned @ 30Hz as well?

Perhaps that will give me the lows, and increase air velocity for intensity.

I've found that the 32Hz boxes I have sound like they choke on the lows in comparison to my current box which get's deep, and stays smooth, at the expense of air intensity.
