Torrent Audio Mistral 12 DVC

WOW! That's an excellent looking design. The recess for the grill is a nice touch.

I certainly hope that you share pics and ideas as the build begins and progresses. I'm quite sure that I'm not the only person new to DIY that will really enjoy seeing this come to life.

On the bottom pic the port width is 18 inches. What is the height of the port?

Edit: I just noticed in the first pic the port height is one inch. 18 square inches of port area should be good.

I hope so. I am a little concerned with the port height. I don't think all port geometries with the same area are created equal. But I won't be pushing the sub too hard so I am crossing my fingers. And as the guy from Exodus audio says: MDF is cheap. If I don't like it I will build a different design .

I was poking around the net and came across this thread from AVS. Thought you might find this interesting.

It's about a mistral 12 SVC build.

Thanks Jon! It seems like all of the build threads I can find are for the SVC. I have figured out how to model subs pretty well in WinISD. But I don't know for example how SVC (different coil) would affect T/S parameters. And modeling the DVC using Torrent's specs looks sooooo good with respect to low end extension compared to other 12" subs I was worried there were typos in the specs.

Oh well, I will find out in a week when my driver gets here .
Thanks again!

I'm really excited to see your build and the resulting performance. I don't really know enough about speakers and amplifiers to properly design/model a sub. My original idea was a 3.55 cu. ft. tube with two 3" ports 25" long. Sonosub.exe showed that it would be tuned to 20hz. That's about all I know. I guess there's only one way to find out!

Jon, I will be sure to post a build thread and I have all the gear to measure it. But I also have a new addition to the family due in ~10 days so don't hold your breath .

Congratulations! My youngest is 10 months old. Kids and work sure make subwoofin' tough to do.

I'de imagine that those are gonna be 10 very long days for your wife. I hope that everything goes as planned and everyone comes home happy and healthy.

Congratulations on the birth of your son. Nice pictures. And the sub looks good too!

Congrats! Beautiful pictures! And the sub looks just fine too. ;-)

I am thinking about this driver in a sealed enclosure. What do you think? It's made for the car audio market though... does that make a difference?
