Suitable mid-hi-speaker for HD215

Hi everybody!


I currently have a set of speakers (2 bass bins, 2 mids and 2 tops) with following elements:

4x RCF L15/554K (two elements per bass bin, reflex cabinet) as basses
2x RCF L12P110K (one element per side, closed cabinet) as mids
2x RCF N850 (one driver with a horn per side) as tops.



I'm thinking of building 2 HD215's using the abovementioned bass elements. Now I'm wondering if anybody here has any good tips on suitable mid-top-cabinet plans to cover the frequency range from 180hz and upwards, and where I could use my existing mid-elements and drivers?

You've exceeded your private message space quota, so I'm asking you in public. What would the price be for those?
