Hi again,

My comment in Post #118 was for the original Kraken 212.

Regards,

Aha, then it makes sense. It's true then. There will be some loss in low freq. and the first dip around 80 Hz will be a bit deeper.

Yes.

Yes
Thank you Petter,

I'll move the Kraken 1x12 forward 4 meters along the side wall to adjust for delay. This will put the mouth about a meter from my ears instead of 4 meters so the large increase in loudness at the seat position will make my little amp happy.

Roamed over to the lumber shop and they could not get 22mm--then you post the designs for 3/4 or 19mm so all is well. This will be easier than I thought! Thanks again and have a wonderful weekend.

Just remember the distances are set to the longest dimension. One edge 90 degrees and the other angled. The 904/906-mm piece has angles in both ends.

I am thinking about building this subwoofer, but I'm in doubt if i should build the 212 version or the 210 version.

So my question is:

Frequency response the same for both? But only a lower SPL for the 210?
Or does the 212 go a bit lower?

I did some measurement in my room and I can just fit in the 212 version (I got 1145 mm space )
So that's why I am considering the 210 version.

Thank in Advance!

Never mind my last question. After I read the thread again I already found my answer.

I decided that I should build the 212 version. I just ordered the subs. They should arrive next week. I am going to build this bad boy in the holidays!

Petter, thanks a lot for the design!

Kind Regards

FYI I finished the build of this subwoofer.

It sounds very good and is very loud.
Unfortunately I don't have a good microphone so I can't do some real world measurement.

Pictures will come if I can get my hands on a decent camera.

Thanks again Petter
