Yes, you could. But it seems like a little waste of a great driver to use it for a sub. EVM 18B or JBL 2040, 2041 etc would do the job just fine.
Amen to that!!!!! Or they can sound terrible (like many VOTs do)Angelo, you are very much wrong regarding horns coloration and horn before mouth test (sorry to say this)
Horn is an acoustical amplifier which amplifies only selected range, which depends on horn's profile. So, when you put horn before your mouth you get equalized sound, so of course it sounds colored. So, yes, you can't get natural sound by using one horn. But with 6 you can
With each of horn you can amplify selected range and combine them to one linear frequency response. But from my experience, coloration comes because of reflection from the edge of horn. Same coloration you have from conventional speakers because of reflection from speaker surface. With LeCleach you can eliminate this. So, LeCleach horns are less colored than conventional speakers, I believe.
Another problem with long horns is that frequencies much higher than horn's profile fs are coming with huge coloration, so it is important to be sure that this sound will be attenuated enough.
So, horns are perfect when coocked right
Interesting...can you show some pictures ? What is the size of mouth, length and which driver do you use ?
My post #64 shows the floor firing 35Hz sub. Here's my other system with floor firing 80Hz horn. This arrangement allows for a near-field listening environment which is particularly suitable for smaller listening rooms.

Interesting design. Space effective
My 25Hz horn is finally ready! Can't wait to try it
This file is recorded by Zoom H6 from listening position:

Yes...I'll measure it soon.
This is how it looks inside:
Do you happen to have more photos? I would love to see the construction of this sub in different phases.
Nice spatial presentation (though I guess it is picking up most of a live sounding room?), but also sounds like it is lacking in lower fundamental weight.
I'm using XY, but also got Rode M5 for better quality.That clip sounds nice, you have the same recorder as me. Which mic did you use, the XY or MS?
I'm waiting for more pictures/sound clips of those massive bass horns.
I'll post sound from Rode later.
Now I want to share my new findings.
My fight with 270hz horn is ended up with adding another horn to the stack!
Initially it was 270hz LeCleach with 1" GOTO SG-505 covering 300-1200hz, than I made it shorter, but after all I put SG-505 in 550Hz Azua horn to cover 600-1200hz and JBL 2490 in 270hz with 4" throat to cover 300-600hz.
And it looks even better
Sounding great. Will you be using one or two of the big bass horns?
After all, I rejected the idea to use it.
It is just too big for my room.
And measurements are not so exciting.
May be later when I have separate building for them
Unfortunately not...this is the only photo I have. I forgot to ask for more photos at different stages.
Yes, at that time...but now I have some solution for bass. I don't understand how, but it works - 15" FC Supravox in 46hz horn:
30hz is room mode.
This is exactly the region where I put most of my attention now.
I have quite short horn (200hz LeCleach) to cover 150-300hz.
And below this I have different options.
GOTO SG-146, 15" Supravox and even 21" ported sub!
And tapped horn, of course.
Before "inventing" 15" Supravox in straight horn, I had 3 ways below 150hz!
80-150hz - GOTO 146 in long string horn
40-80hz - 21" ported sub
20-40hz - tapped horn.
This bass is great, but too much furniture for my room.
Now all of them are replaced with single 15".
But still I'm thinking how to make GOTO sound lower than 150hz...80hz will be really great! And I have one idea - I'll share later!
