So you want 186 on this horn,for some reason,and flare extension as well?

 Its just interesting how some go for little drivers and longer horn,and some go for 18"s or MULTIPLE 18"s on a short horn

the 15" version we just built is huge! [doesnt fit through a door]

100cm x 76cmx 76cm .......

they wont fit through our door,
i think your better of putting a proper sub under them..... like a lab horn [or4/6] and using a good set of mid tops, than trying to extend t he response down lower...
 
hmmmmmm, i like that idea a lot!!!

it takes all sorts i guess.
 
what i want is both of the above... big driver and longer horn.
 
time is running out as i want to start this by the weekend, otherwise i'll resort to the original plan of building labs and hd215s. 
 
lets try and clarify this project specification...
 
1.  must use an 18" driver.  it would be nice if it was p.d. or something of similar quality/availibility.
2.  be a sub and play low freq
3.  be able to fit through a door
4.  size unlimited [see note 3]
5.  be used in groups of 6 or 8
6. max height to be no more then 2m stacked in groups
7,  width of stack unlimited
8.  not be overly power hungry
 
i hope this clears up things for ppl who want to help...
 
the size is not a problem as if it gets too big we can always split it into single 18's.
 
lets not worry about the extension for now.

Perhaps make the horn fit (totally) in the extension during transport. Using some parts that flip, the extension with horn will be just little larger (say 5 cm in each direction) than the original.

This way a 18" horn with 12410 cm2 moutharea, 245 cm length, 60 ltr rear chamber can be fitted into 65 x 65 x 130 cm when packed (60% of unpacked version) while still nicely braced.

The  18" horn that tb Mike from NZ suggested above is the simplest to build but very large and heavy. It should be a killer sub.
