isobaric T Line?

[Jroo 10+ year member]

I have 2 8ohm drivers that I was looking at doing a t line with. Can I clamshell them in a isobaric and still do a T line? If so, how would the math change? Would I treat the design like it is only the single driver there and wire it up correctly?

BTW, who would be the best person to go for a design with?

The purpose of isobaric is to cut down on enclosure size.

A transmission line that is designed properly will be far bigger than what most people would consider practical so the two don't really go together.

You'd also be cheating yourself out of some output versus mounting them both with both cones exposed.

You would cut the line area in half actually as you would basically have twice the motor strength. Still, pretty pointless to do with a transmission line.

Line area has more to do with cone area and Vas than it does BL. But we all agree that it's pointless. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Mounting subs in an isobaric fashion is to keep the transient response more linear and save space. A T-Line takes up a rather large amount of space and is as linear as it gets (bar infinite baffle mounting) so mixing the two is a bit counter-intuitive. Would it work? Yes. Would you see different results over using a typical setup? Well, sure... You'd be spending extra money on twice the subs and almost twice the power to sound **** near the same //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

I disagree on the Vas being that useful for deciding line area. It will play a role in power handling but that shouldn't be something to worry about. With the proper line area calculated using your desired 1/4 wave length, BL, Sd, fill amount, Re, and Qts, you should have proper power handling, regardless of Vas. And in the equation, both BL and Sd are squared making them the prominent factors in deciding line area.
