My current double 12 inch tops that I have built  https://forum.speakerplans.com/tilted-tops_topic105463.html" rel="nofollow - https://forum.speakerplans.com/tilted-tops_topic105463.html have some flaws (shitty disperion from the 12 inch speaker not coupling corectly above 500 Hz, x-over center point between mid and high is @ 1 KHz.

This is what I came up with:

in this design at the top of the speaker there is Limmer 870qx horn that will take care of 500 Hz and up, below that , two 12ndl76 that will work in 65 liters 90-100 Hz to 500 Hz.

Also I have taken into consideration Limmer 042 horns( would prefer this one because of the wider dispersion than the 870qx) , but 042s make the speaker a little to wide and I can not keep the internal volume @ 70 l as i want for my 12ndl76 (speaker has to be very shallow in depth) , I tought of putting the 12 inches in a V config like the RCF 4pro6001 speaker but I have no ideea of the interaction betweeen the speakers in the V positioning, that would not make the speaker as tall as it is with front baffle positioning of all components.

what do you guys think? how would you aproach this design?
