Hi everyone, I've been reading alot and mostly searching alot for the past week. I just ordered 2 Kicker cvr 12'' (with dual 4ohms voice coils to be wired in parralel) I will be driving those with a 2 channel (600W RMS max @ 2Ohms / channel).
The specs tell 1.75 to 2.25 ft³ per sub excluding port for vented boxes. I've found this forum by the free box plan thread by moe lester and I used Win ISD to verify few thing and all and im concerned about the fact that the design I was to choose put the two subwoofer in the same airspace and since the subs are powered by two different channels this could result in sound cancellation and also if one sub blow the remaining one get twice the volume. [My real question is above]
Im referring to this design here :
But there like 5 other design that are interesting for me in the cubic feet range I want. (about 2 to 2.2 per sub)
What you think about all that ? Should I put them in the same airspace and don't worry, or I should separate them and make 2 dedicated port or make a center port(if this is even possible in the way that doing so could result the same as putting them in the same airspace ???).
Another question : If I make 2 chambers, can I tune the ports differently for each sub (ex: one tuned to 30hz and the other to 35Hz) Will this give me a great result or just junk?
And finnaly : Im a little confused about the tunning frequency, which should a choose ? Do I need to get the closest to the fs (which is 26.1Hz) or it more matters on how I want it but you know, it's my first custom box and i know really know what difference it will make on the sound between let's say 25 30 35 hz tuned port.
I know there's alot of question and they maybee a little unclear as english is not my first language but thanks for reading and many thanks in advance for the answers !
