I am writing this comparison cause I am reading this forum for a while and found that JBLs are highly recommend for the budget 5.1 setup and I just bought infinity IL10 and IL25c center two weeks ago. These recommendations made me little worry bout my infinitys and I was wondering if I made a wrong decision. So to clarify the matter I called my local dealer to ask if I can compare these two brands and he gladly allowed me to do so. our comparison included following speakers and amps: Onkyo CD/DVD player (dont know the model) Onkyo TX-8511 Harman Kardon Avr320 infinity IL10 infinity IL25c JBL S38II JBL S center so we started with two channel music and I played every type of music available there, rock, pop, R&B, jazz, classical, etc. I found infinity much much clearer than JBL, JBL was too forward in mids for every kind of music, Only thing sounded better on mid and high frequencies on JBL was strings. JBL wuz not as clear as Infinity for my ear. But JBL produces bass little better than Infinity but again boomier than infinity. Then we tested some 5.1 stuff and again infinity wuz clearer than JBL. I heard every single detail. Then for my curosity I checked Infinity with axioms, paradigms and klipsch, and surprisingly Infinity won the race against axioms and paradigms, but klipsch sounded better than infinity, I don't know the model I think it was sb-2 or sb-3. but it was more expensive than infinity. to conclude I will say that its my very own opinion and maybe you guys don't agree with me, But I will suggest that If you are in the market for budget speaker setup, give it a try to infinity interlude series and hear yourself. I am a very satisfied owner and specially after this comparison.
