So, the question is still opened: how to get 300-400hz.

Perhaps give the JBL 2169H a try. It is supposedly very good from 300Hz to 2.2kHz, but I have never tried it. Use it in a sub 200Hz tractrix horn with a 4" throat and sensitivity should be around 108dB/w/m. It is an 8" cone compression driver. |

8" diaphragm....isn't it too big and heavy ?And with 1st order I'm not sure...I'll try JBL 2190!This is the only modern driver which can do it.I've decided not to go for clones of old design.If not work properly, then I introduce another channel for 250-500 range...may be based on JBL 2169H! |
