2 15's in a 4th order enclosure

[Sid420]

hello

I am going to be buying 2 american bass hd's and i was looking to run them on 2000 watts a piece and i was wondering if anybody could give me ideas on the box i want it to be on a 4th order but dont know how to build one. so you help me to figure out what i should have it tuned too. i would like it to be a low end machine. thanks

Are you stuck on the AB HDs? They arent the best choice for a 4th order is why I ask.

Id recommend looking for something with a higher Qts and lower Fs if you want to build a 4th and want the lows.

well i already have one of them so i was just going to buy another one and build a wall but i figured a normal wall would be to big for just 2 15's so thats why the idea for the 4th but i was also considering 4 of the AB's with a normal wall.

Wait, you thought a 4th would be a better idea because it would take less space? A 4th will take more space that a typical 4th order. You'll have a sealed side built to specs of what the sub wants and ported based on a ratio of your choosing. If your subs are not designed for a sealed box, they aren't ideal for a 4th, as mentioned already. The higher QTS and lower Fs is definitely going to be more suited for a bandpass enclosure. It doesn't mean it can't be done, but it's a gamble that no one will be able to tell you will work or not.

As far as 2 15s for a wall, you don't have to utilize ALL the space for the wall. Just use what you need for the 2 subs and maybe make a trim panel for the void space?

Those subs will not be a low end machine in a 4th. Do 4 of those 15s in a regular wall on some power and you'll be muuuuuuch happier than a 4th with 2 of them

i was thinking doing 2 15's on a 2000 watts a piece.
