Seems more realistic, and pretty reasonable too.
Take it they're quite low powered drivers?

For sure you have got it wrong.

There is absolutely no twin 18" that will take 1000+1000=2000 watts on 3 tiny 4" ports on this planet.

Don't be shy. Just name the 18" you are trying to build a box for. If it is of any use as a subwoofer, I will suggest you a design.

He is trying to expand on the G-sub using the Dayton PA465S drivers. He has increased the port size so it's all good now Smile

no top secrets hereit's my take on a G SUB and as Partyk pointed it out I will be using the Dayton PA465 .I have change the enclosure volume and port size to suit the driver.as for the ports being aroundit is my understanding that it's a more efficient design.

Good to hear Thumbs Up 

You can upload photos to an image hosting website like imageshack and then link the album to here Embarrassed

Alternatively try reducing the size of the photos and see if that works Wink
