Happy new year to everyone! Well im thinking of trying a new horn on my JBL 4560 instead of my 2390 horn/lens i use now. The problem is that any crossover point upper the 500hz make the speaker system to not sound correct. At 800hz the blend of the mid frequencies with the lows is not good and you can hear that. So i need a horn that goes down to 500hz . I got the 3115a , 3110a and 3152 crossovers (also some active ones). On woofers i got the 2220 , 2205, e145, k140 , and k130. On horns i got the 2355 (total crap), the 2380 (smooth down to 500hz with great blend with the lows but missing the detail of the 2390) , and the 2390 lenses that most of the time i use the 2309 horn only cause i really like its attach and uncolored sound. I was considering the 2397 smith horn but i know that its loading is limited to 800hz only :/. Any other ideas? Regards!
