Interesting setup. What factors were at play that led you to go band pass with that driver?

What do the models look like and what are your impressions of it?

I wanted a sub whit max impact < 20 hz.
Bandpass has a flat line to 16 hz and 15 hz - 3 db.
This give,s not bass but pure energy.
Compared to a normal vented box i have 6 db more output at 20 hz,that explains the energy going to the floor and airpressure from this subdesign.

Wy this driver,i am a big JL fan,and the calculation says it can be done.
So i dit it.

The model from Winisd you mean?

Yes, I was curious to see your model.

I too like JL Drivers but have rarely seen them used in band pass applications.

Very nice build.
From this picture the LCR look a bit higher than ear height when seated. You should angle the LCR down towards the couch facing your TV.

You could use door stops or something like these,

I have to remodel it was some time ago
JL driver works very good in this bandpass.

If i angle, it slide,s of the tv.

I found it:

18-75 on paper.
I measured: 16-70 hz flat inroom,15 hz- 3 db point.
airspeed: 11m/s at 22 hz.
