When I am comparing subs online, is there any spec I can look at in particular that is going to tell me what sub can perform clear and detailed and perfect at low volumes, and what subs can't? I mean they have spec sheets that tell you which ones can play at 20hz at 100spl, which ones can go down to 15hz, etc, but what am I supposed to look at just on these sites that's going to tell me this one is detailed at low spl and this one isn't? Or are all the top brands people bring up here going to do equally well at that, outside of maybe the sealed vs ported trade off? All the sealed top brands people mention here will be equally clear and detailed by sealed standards at low SPL at similar sizes and costs? All the top ported brands people mention here will be equally clear and detailed by ported standards at low SPLs at similar sizes and costs? Or are some brands or models known for that, some not? Some drivers do well at that that the top brands use, and some drivers are poor at that but perform more detailed at high volumes than the other brand?\n\n\nThe same type of question, but am I at risk of this happening if I buy one brand vs another? How will I know which of the top models have this problem and which dont, or do they all not, only crappy cheaper subs? I know the room also plays a huge role but I cant change my room for better or worse, and there's no way to know ahead of time, so that's why the question is focusing on the subs.\n\nMost subs should sound very good at low SPLs. Look at any of the often recommended brands around here; they all do fine at 100dB and below. Hsu, SVS, and Monoprice Monolith are a few brands that are all solid. By the way, subwoofer range frequencies do not contain much of what anyone would consider detail, and that is even more true at lower SPLs.
