Very good, thanks for the images. It would be very interning to learn what the bandwidth of the horns, the bandwidth of the drivers and the specificity of crossovers you eventually chose to use with each channel. It might take for you for a while to figure the things out but please when you feel comfortable with the results then post the information.
Of course, so far I've moved the crossover point from 200 to 300hz... sounds better this way
1) Your tweeter and your MF channel need to be time aligned. You might raise the platform use you tweeter and slide it all the way back or you might flip the HF and MF channels and position the MF above, it might be too high though… In the later configuration your deep-seated tweeter will be shoring is a narrow window, you might re to lie it 90 degree on its side, letting the slot to shot horizontally.
2) I do not think that you will be able to time-alight the upper bass channel but you need to wave-align them. Make sure that upper bass and MF tit the top of the wave at the same time. the will be at the different periods and you will have same comb desertion but you will have still better result than if MF and upperbass channels cancel each other.
I know you're not a big fan of digital delay, but I'm using behringer DCX 2496 to make things easier... this way I get to keep all horn mouths on the same plane which avoids some reflections (from other horn mouths).
3) Extend your horns closer to the middle of the room. I would move them right to the edge of the carpet.
4) Use horn winder. It looks like you have 5-6 feet on right and left that might be used. With setups like this and in the room like this you might be able to get not 30 degree angle but rather 60-70 degree angle between you and two speakers.
I don't know what the advantage would be, can you explain a little? Thanks
5) Use the following sequence:
- a. Properly crossover all your drivers and integrate them in a way you find appropriate
- b. Move back and force from your speakers and detect what is the minimum integration distance (Dmin)
- c. Put your at 1.1-1.5 of Dmin and begin to move speakers wider pointing speakers to own solders.
- ........
Will do, thanks.
7) Flip your bass channel 180degree making port to “read” the floor.
Saw that one myself after I took the pictures
