is there any diff between HB and HA? - Fs and Vas are higher/lower than some speakers but should work well in a Karlson - CXA has Tannoy type feed versus the ~3"x6" horn. Have you ever tried putting a foam or felt ring behind the horn and over the outer spider (where a dustcap would normally be)? - that cleared up my C15CX somewhat and could be seen on graphs
fwiw here's 15cxha's published specs - dunno how accurate ~same specs are given to the hornless model (15cxa)
