listen. I am doing 18s, period. I currently have 12s and yes they sound great, but i love the lows.
And to whoever thinks 18s sound sloppy needs to build a good box for SQ use. I can make a 10 sound just as sloppy as an 18. Throw it in a 12cu box and i guarantee its sloppy.
And im going to get a box design from pete kulicki for a strictly SQ setup that goes low. I know how its going to sound essentially. I dont want input on size of subs, just which ones. I was thinking the 18 ssd. idk if my budget will allow the q's
