so whats the deal with round ports... wouldn't it be al ittle easier to build a ported box using these? can someone fill me in, these don't seem to be all that common in car audio as far as i can tell. How do you design and build one?

I love round ports

These two pics are of my wifes car. I had to stay mild. She told me "no more than one woofer".
In my opinion, round ports are a little more predictable than square or rectangular. Design of the box requires a little fore thought. Ported boxes are usually about twice as large as a seal box for the same speaker but their sound output is typically 3dB louder.

Most of the time I use WINISD for the design. It can be downloaded free at http://www.linearteam.org. I also have BassBox Pro but still prefer WinISD. Its easier to use.

Download the program, play with it and if you have any questions ask me

i already have winisd. I'd like to maybe try to build a ported box with a few round ports instead of square or rectanuglar.... You do great looking FG work though, i like. do you have any build up pictures of your work?

With an aero port most people see gains of under 1 dB...

They look cool, but not exactly cheap...

Always use the biggest port you can.

when porting with round ports are you still getting the apparent 3dB gain over sealed?

i like round ports they are really easy to do and cheap. go to the hardware store and get some 4" or so plastic pipe it works really good and cheap. also to svo ranger that box looks pretty good but why in the hell would you make a 5 sided wood box and do one side with fiberglass? i think that has to be one of the ugliest ways of making a box. no offence just kinda curiouse.

Simple and fast. Wife did not want me to get carried away and I refused to build a regular MDF enclosure. This was the only compromise that I could live with.

And no offense was taken. I love to hear the opinions of others.
