I was trying to get a nice response for my JBL 15" in hornresp,and look whats best! conical horn !

its like the underdog of horns=
People proclaim the magic of tractix mid, and expo/hyp bass,, and the poor conical gets left behind outside PI circles...

No the jbl horn isnt small- that rear chamber just cant be reduced !
so il build my LAB12 horn next,as the rear chamber is very tiny,and the entire horn small

but i Do want to build the jbl horn :-P

Other news:
RS SPL meter , waiting for delivery(it is xmax after all)
enough money for lab12 very soon.. :-)
