    Posted: 05 October 2017 at 7:01pm
Hi,
So I want to build I dance stack to play quite transient, kick driven electronic music. (Example: https://www.youtube.com/watch?v=_WQwoIWClUQ)

My (current) plan is to build: 
 2 1850 Horns loaded with Void V18-1000 for sub
2 X1 Subs
 4 HD 15's loaded with PD 184's for kick
Something to meet the coaxial


For mid-highs I want to use one of BMS's coaxial compression drivers with a casted horn. I'm wary about getting one for each side, this would surely be overkill? Also, would a 1.4" be worth the extra investment in my case or would the 2" do the same job just fine? 

Any thought/feedback or advice would be appreciated. I'd very much like to know if this is a solid choice of cabinets and drivers for what I intend to do.

Extra info: 
This is a project, it's not for a large space or a certain size crowd. It's more about building a system thats plays this type of music with a quality and coherent sound that is both loud and clean. I am open to suggestions that completely blow my current plan out of the water. 

Thanks!

edit*In review the plan has changed somewhat, and I wouldn't be surprised if it changes a couple of more times before it's solid Confused

No point running 1850's with hds swap the 1850 for x1's and stick with the hd's.

Thanks for the reply, could you elaborate on why the x1's would be a better choice?

A pair of 1850 will only respond to around 50hz and will rapidly dropp off below that if your playing electronic music then the x1's will add that wobble that the 1850's wont pick up cross them over around 80hz and let the hds play from there you ideally want 4 hd to 2 x1s for a nice balance

It looks like you miss a fifth way, hd15 or cubo 15, or any bandpass horn, will never reach even the best bms coaxial, you need something to play at least 200 - 650 Hz... Or exchange the hd15 for something 90 - 600 capable

I was thinking there would be an issue with the coaxial hitting the low mid, thanks for confirming that one. Is there an option thats capable of 90-600?
If a fifth way is a best way to go I'm also up for introducing another cabinet.

Short Version; 1850 isn't a Sub

Maybe try simming some bph 12's? Ive seen some recently on rigresale that met a coax, think they were called rb212, might even be still selling. Anyway the soundsystem that were using them was called unstable or some in that vein.

RB212s are a FLH not a BPH.

Ahh well that explains why they go high enough to meet coax.

To OP - i re read your post and i see its for a project, so im guessing buying might not be in keeping with what your wanting. So with that in mind there are designs that might be able meet a coax such as the martin 115 and martin 215 mk3, but i am only guessing.

I think a 12" design would be better, but dont know of any (apart from the rb212 now hah). Maybe you could have a stab at designing your own with the help of the forum, if you know any horn theory and have used hornresp before?

Or maybe the bass section of the xtro could work.

Found these as well, they are all 12".
