6th order with 2 t-line ports?

Is it possible or worth it?

uuuhhhhhhh.

You mean a 6th order with really long ports? yeah. You can do anything. But you dont want both sides of your bandpass tuned super low or it wont have a good range of playable notes. Maybe one side is tuned to i dunno, 25hz. That might take a port as long as 50 inches, so then you need to put that somewhere, so it snakes/zigzags so you dont have this huge 50 inch long tube as your port. As for the other side you usually tune higher, maybe 45 or 50hz to get that upper end. That will probably be a short port, 10-15 inches maybe. It all depends what sub you have and how much room you have to work with. Bandpass takes up a lot of room.

The problem with this is that a t line works on the principal of constructive interference. Essentially it joins the front wave and rear wave together in phase which increases output

Not saying it isn't possible but it certainly becomes more complicated when you have a phase that isn't zero

that's a box with 3 equal length ports. tune tbd box to a tune of say 28hz split into 3rds

a 2/3 section and a 1/3rd section. bu.make all 3 ports the same lengths. This will help control xmax at upper and lower hz. so you can put more power to a sub Then rated.

do some research. it's not a easy box to build. but lots of fun.

How about you ACTUALLY build this box and hear what it sounds like before suggesting it as a successful design or not? I'm still not sold on this design and I'd want REAL unbiased reviews of what it sounds like from others before giving it a go ahead and suggesting it to others. It's a lot of wave manipulation for a driver that has a simple job.

What's holding you back from having this box built? You've had your sub for quite some time now.

Sloppy kisses as always AJ ;)

Im not the one you want to try to troll. Just a fyi for you.

you got beef with AJ ? hahaha

I was feeling the same way though, I wouldn't recommend a box to someone if I haven't even built it.

the reason im asking for advise is because ive only built sealed/ported boxes.

ive tried to make a 4th order but I made it way to small lol. it wasn't a success. BUT IM NOT DISCOURAGED.

im still very interested in making bandpass boxes.
