    So I am going to buy new monitor speakers... I will buy one sub woofer and two mid-highs no matter if 4300 or 6300.I want to know if 6300 are better enough to pay half more money for them.They got one extra higher mids speaker,I love making crazy multi oscilator sounds,very thick... will it be better for this type of sound to have 6300 or 4300 are enough for real proffesional production.Both 4300 and 6300 subs are neodym 12" that go down to 27hz so I dont see big difference in them I think.Please,help me to pick best thing for money,thanks :)


    will upload specs later,my internet is fucked and cant load JBLpro.com properly

    whole 4300 setup will cost me 2700 euros,6300 is for 4000 euros.I will go for 4300 but I think 6300 might be worth the extra cash,what you think?

    Depends on the room size a lot. You'd only need the big ones for a BIG room, like 5m x 7m or something. In a smaller room they're just overkill, you couldn't even bang them loud enough in a regular bedroom.

    TBH even monitors with an 8" woofer are overkill to a normal bedroom studio if you have a sub in there as well.

    I have 8" woofer right now and I think 12" would be perfect.I know what you mean and agree with it,bigger isnt allways better.I will use that 12" sub in place that you will call overkill but I will use it at rather low volumes for better clarity of sound.8" can be enough at half volume but 12" can do it at 25% power = less distortion = better sound. Thanks for for tips kama,I understand that this huge amount of photos and speaker information is boring so double thanks to you mate


    I want to use bigger subwoofers for their ability to rattle whole room at say 30hz witch is freqency where similiar quality but smaller woofers hardly makes any noise even when you put your ear to port of sub.

    if your getting these for studio monitors, at 4000 euros there's alot of other (prob better) options. if your getting them just to thump tunes then you could get a hk lucas rig for 1500ish and that'll piss your neighbors off a treat. i dunno, but i agree 100% with the 8" woofer being overkill.
