SPLadd1ct Posted January 9, 2012 Report Share Posted January 9, 2012 most 4th orders are used for burping because you can build them to get loud at a certain frequency, but i would not recondmend them for a daily setup because they are very peaky. example: it might play 35hz very strong but anything over 45hz will be very quiet. bandpass boxes are known as "one note wonders" which means you will hit like 1 out of 5 notes in a song. i use to have an alpine type-r 10 in a 4th order and it was alright, but then i build a t-line for it and it was a night and day difference plus it got just as loud. there are different ways to tune a 4th order. You can do it the way your describing it where you get a small range of Frequency response, and you can peak very well for competition. BUT if they are tuned right They can give a wider stronger response than a ported box. They are normally very efficient, if built right that is. x2 Quote 2011 Ford Ranger Sport 4.0 v6 2 sundown audio prototype nsv4 15s crossfire 4k wired to 0.4 ohm 15 banks of maxwell 3.0 caps @ 18v triple alts (x2 us alt 250's, x1 singer 320) 153 at 23hz Link to comment Share on other sites More sharing options...
