I'm planning to buy a LCR Setup for my little home studio. Mainly I will do all works of sound post (dialogue editing, Ambience/SFX, sound design, foley as well as rough mixes). Critical mixing decisions would be made elsewhere. At first, I wanted to get 3 Genelec 8020's but since my room is not ideal and untreated my go-to sound guy told me to save the money and recommended JBLs and a good pair of headphones.
On my search I found the JBL LSR 305 monitors which are very affordable and get many positive reviews. However, I only found reviews in music forums not concerning sound post in particular.
So my general question is, what are the different requirements of music monitors and sound post monitors? Are monitors which are praised in music forums generally also good for film sound or does it depend?
For my case, does anyone have an opinion concerning these monitors for sound post?
