Passive Radiator

What? The sub requires a small enclosure, which is why they recommend a PR. You would need a good amount of port area and that would cause the port length to get very long, which would take up a ton of space, to get a nice low tuning. To save all that effort, you can use a PR and save a bunch of space. To lower the tuning on a PR, you just add mass to the system since the radiating area is staying the same. That's the same thing you're doing when you add port length -- you're adding mass while keeping the radiating area the same.

Ok.. what I really want to know is how to build a good ported box for the TC10 OEM I have to use a 10" or 12" PR?

If you got the Passive Rad you will need the matching Powered Sub for it..

For Best results..

You donot port a Sub/PR setup you seal the box & install the PR

ohhh i see so if i ever wanted to port the tc10 OEM i would have to use a PR because tc says thats the only way to make it work right. I get it now... Anyone have pics of how a sub/PR set up should look like?

The Pic you are looking at is a 1cube box sealed

The PR is on one side the Sub Is on the other..

Its one box, The PR runs off the air the Powered Sub Moves

In this pic the Sub is pulled out & the Pic is in the mounting hole of the Boston G5 12" Sub

You just need to have the passive radiator displace about twice as much air. It doesn't have to be specifically made to pair with the sub. That's like saying you have to buy the amp from the same company to get the best results... it's just not true.

No, that's not true. You COULD port it but your port is going to be huge. This takes away from the idea of owning a sub that works well in small enclosures. The only way to stop this is to make the enclosure larger which will make it peaky like they said.

Bring this back. Do you have to buy a certain type of PR, or can you use any sub (proper parts of course)

I'm also looking at the OEM 10 and looking into PR's. I did some home work on them and I understand how to "tune" them and I under stand what they are. I'd also like to see some more pictures (overall pictures would be nice) of PR so I can get a better idea of how they look.

Here is a good link for explain PR's...
