Hey guys, I currently have 4 15" Ultimax subs in sealed boxes. I like sealed boxes better. Would it be a noticeable difference if I upgraded to 4 18" Ultimax subs in sealed boxes?
Power being equal (I am running a CV-5000), room being equal, placed in the same spot and all that, would it be worth it? Would it hit lower, louder and harder?
Any input is appreciated.
I'm going to go ahead and assume that the 15's are in 3.0cuft boxes and you'd planned on using 4.0cuft boxes for the 18's? If this isn't right let me know.
If so then you'll only be gaining ~1-2db of max output due to the increase in total Sd. If you upgrade the amps as well, then that could bump up a bit higher, but honestly I don't think it would be worth it unless you can go with a lot larger sealed boxes in the 6 cuft range so that you would have added efficiency in the lower octaves. Going from a 4 to 6 cuft. box nets you +2db of output at 20hz for the same amp output.
