Default Line array Open Baffle using Line array wavegudes

Hello everyone. I would like to ask here about a line array waveguide/horn that I have seen in pro audio. I had the idea of doing an open baffle speaker using 4 12" drivers and multiple
PRV Audio WG2-230Ti in a line array vertically aligned at the side in mirror image configuration. Pretty much the sight of an Infinity IRS. These waveguides come in single or dual driver configurations and I would like to know if this is factible for a home audio application Now, I would like to read all kind of opinions and will be very welcome.

If anyone haven't noticed, I specified that I would really appreciate ANY comment or opinion regarding this Idea. So, even negative comments about the idea are welcome...

It's difficult to see how they would come together. Open baffle to narrow line array. Why aren't you sealing the boxes?

I want the unboxy sound and use multiple compression drivers vertically to create a cylindrical wave, if you can visualize it. pretty much like a Magnepan but using dynamic transducers that can handle and reproduce to higher levels. I am biamping and using active crossover/DSP..

These waveguides have a 140 degree horizontal dispersion pattern so vertical reflections are minimized as well as the bass with the 8 pattern.

I don't know what you do to your boxes, but I don't have boxy sound. What about the room reflections, are they intended?

What about below the cross.

I’d skip both the 12”woofers and the OB.

You won’t get array type wavefront with an OB

12” is too big to keep comb filtering at bay which is primary design criteria for arrays. 8 6” midwoofer would be the better option.

Hello. Interesting idea, although the concepts seem to conflict; a dipole stimulates the reverberant field whereas a line array does not so much.

It is a constatation or a personal conviction ?
