Purplehaze Posted March 30, 2011 Report Share Posted March 30, 2011 im looking for a fourth order bandpass box design for 4 18s. Specifically the fi btl n3, tuned to 29 or 30 hz. im planning to put it into a new yukon xl denali. i was wondering if anyone could help me build one. and if anyone has heard about the n3s yet im really curious on how they play. Wow, everyone needs to go a little easier on this fella, he doesn't claim to be an expert, and he clearly asks for help right off the bat. Damn, remind me not to ask any stupid questions around here!

It gets old people coming saying they are doing 4 18"s on a million watts. Then post up stupid shit. When they clearly have no clue about anything.

We were saying that because he wants to run a burp sub lol..thing has a fs of like 55hz Kind of funny to say, that its a burp sub because the fs is 55hz. Some dc subs have way higher fs when received new. Not only dc but other brands too.. Quote Thinking is the root of all problems... You ALWAYS get what you pay for.

Sanitarium Posted March 30, 2011 Report Share Posted March 30, 2011 (edited) my 4 18 4th order = my old 6th order (just experimenting with it. wasn't built to be a 4th order) lol. 21 cubes rear 13.5 cubes front, 45 hz tuning, still gets plenty low. We were saying that because he wants to run a burp sub lol..thing has a fs of like 55hz right right. OP. i mocked that up for you. pink line = mine as is, green = mine as if tuned to 30, cyan line = mine as if tuned to 30 with the subs you're wanting.
