Default Crazy horn idea

Have carzy idea that I want to try anyway. But I can do it only in case if some one here will be kind enough to calculate correct horn flare and to set it into desired volume with all turns etc. I`m not clever enough for those things)))

Design Idea:

1) two 8 inche FR are loaded common camera and BLH, BLY is loaded room corner.
2)One of FR is firing upward - omnipolar, far enough from walls because of cabinet proportions.
3) Second one will have external side closed with some felt bag, so, working just for hor.
4) Its Mono. Increasing or decreasing volume of the closed driver - we can easily adjust bass level.

Thus I do not need to make additional bass speaker, no biamp, get sweet spot for everyone in the room, can adjust bass responce using exactly the same speaker as for mid/high.

"Brutal" scatch is attached (just to imagin the idea) dimensions: height - 120-130 cm, depth - 150 sm, width - up to 40 cm.


The room is about 4 x 5 meters, 2.8 height.

Pls, make critics. Just let us dont tuch topic Mono vs Stereo.
If some one will be kind enough and crazy to calculate that with hornresp and help with drawing.... than building will start, probably.

Interesting. One thought came to mind, if you don't mind. I wonder if it would help with focus to have the full ranger facing forward as you have it, but contained within the cavity just below where the driver is right now. Then have a bass driver pointing up, or side mounted, using the horn's flare.

Or, have the top driver mainly supporting the low end instead of the full spectrum.

This just hit me, no science behind it.

Yes, I was thinking about the driver in that cavity:
+ opposit drivers will cancel vibration from each oth
- dont like the driver sound in closed volume, conditions for workin of both drivers will be too much different. And I want to use advantage of the exactly same drivers with same parametrers and sound are playing bass..

In case if driver looks forward we get a lot of possibility to play with it: felt bag, variovent, closed box or even..... both drivers opened.

Regarding upper driver using only for bass - not good for me, because I need omnipolar dispersion of mid/high.
