Hi HenryI think Martinelli's horns are really great too. Awesome looking and I hear they sound really good too.
I'm doing a 3-way at the moment with HF horn, midrange horn and direct radiating midbass/bass. Quick rundown the HF horn is JBL 2370 horn with P.Audio PA-D45 comp drivers, midrange horn loads an Eminence Alpha 6 driver, and the midbass/bass section is JBL 2225. Crossover point from bass section to mid horn is 300Hz and from midhorn to HF horn will be 2KHz.
