Is there a way (other than by measurement - esp. if you don't have the equipment) - to predict / calculate room gain for a subwoofer?
Vented vs. a closed box design (for the same driver) - can yield upto 18Hz different in F3! (ie. F3 for a closed box Shiva MkII 12" is about 38Hz - vs vented (although larger box) = 21Hz).
I want to use a closed design - because it is supposed to give a better transient response (I mainly listen to music - and would rather have speed than bass extension) - however I feel an F3 of 38Hz is still too high for pop / rock music.
I know room gain will occur - it would be nice to be able to determine this - to see what the in room F3 would be of both boxes.
Thanks,
Dave.
