hey everyone , well i m intending to build a small setup for small to medium events . so I ve purchased 4 eighteen sound 12nd930 12'' drivers , two 18w2000 18 inch drivers and two ND1460A 1.4'' hf drivers and two XR1464 alu horns . i also have two 10w500 10 inch drivers and two rcf h100 horns and a BMS 18N 850 18'' woofer. The big problem is that m still so confused of what i will build or what to go for .. either 2 dual 12 mid tops or i purchase two more hf drivers and go for 4 single 12 tops , either reflex or horn loaded subs ... so some ideas will be really useful .. thanks in advance .

Buying drivers before you know what you're going to build isn't the best start but you've definitely got the basis of a good system there.
If you want your two sub drivers to keep up with your four mid drivers they'll need to be high efficiency, but the 18w2000 has a rather disappointingly low 7mm of xmax so their performance in horns won't be spectacular. A pair of TH18 tapped horns with 2x12" midtops in stereo and the 10's made into monitors would be a respectable and fairly well balanced system. If you find your bass end lacking after that build two more. The odd BMS woofer shouldn't be mixed in with the 18w2000's, but it does open up a second option for system design if you really want to make use of it: The huge excursion capacity and all round performance of the 18n850 would make it suitable for a single high output extension sub, playing 30-60Hz or so. Then you could load the 18w2000's into a design which could play loud from 60Hz and up (or maybe 50Hz and up without the sub) without encountering such major excursion problems as you'll experience if trying to run them low. I'm not sure what the best design for that would be, and the single BMS sub won't be enough to keep up with the two 18w2000's but it might come close if running indoors and always strategically placed (corner loaded), and would give you the option of some strong 30-40Hz which you won't get otherwise with these components.

Thank you for your answer it makes sense . So as i understood the 18w2000 small excursion won't allow em to play low enough in certain subs ! I was thinking of planar waveguide subs such as the dynacord fx20 , won't they match with that box ? because the original driver of that sub the evx 180 b have an max excursion of 6.4 mm and they sound good at the very low end !
