| Okay Ethan you state some companies call it rock wool but rock wool is limp and seems not to be as dense as 703 . According to one suppler that sells rook wool states that rock wool is only good for 100Hz and above is this true? biggest problem I have is budget. I can buy 2 panels of rock wool for the same price as one panel of 703 my question is since I can buy two to one, which also in your info. you claim acoustically that rock wool is equivalent to 703, which would be better the 703 or the limp rock wool according to my Frqz. analyzer I show huge spikes in the 125hz and above in my new room even with 6-703 panels I already made. I now my mixes have that one note bass thing plus I have a weird ringing sound coming out of the monitors when I DI the bass or palm mute a D tuned guitar through a half stack at medium volume. Never heard it before until I moved everything to the new room which BTW was my x-mas gift from my wife. |
