Hi sir good day! Kindly enlighten me coz I'm planning to get B&C 21SW152 2000w, which one is better box designed suitable for this driver WS21X or bandpass ultra sub? Your answer would be much helpful.
I’d like to have this scaled down to 12s and 15s ! It would be nice if you could make the front wall move in and out for like tuning purposes with different kinds of subs they always want different cubic feet ! I’d say on calculations just that part in the middle is the internal volume of air for the box ? The rest off the back wall is all considered to be port . This would make a 4 th order box by adding a sealed box in front of the subwoofer built like the octagon shape ! I like the way the ports are on this box it just looks so mean like it’s got all of it coming right out to you ! It just looks loud like the db’s would be outta site !
