is there any difference between these port designs??

[oldsoundguy]

I want to know which one of these port designs would be better or is there any difference??

Are they the same?? I want to build a box for a single 8 and want a net of .75 tuned to as close to 35HZ as I can get.

I used Torres design and every size box I try it calls for a two bend port. So I was wanting to know if there is a difference between these two drawings of the ports??

Box #1 would be my preference since it avoids the 180 degree bend box #2 has. 180 degree bends are worse for efficient airflow.

Thank you so much for your response. I will absolutely take your advice.

what are the possible real world differences in those? IE if I built both and listened to them back to back, what would I notice in difference between them?

Is this new drawing of number 3 box possible?? each slot would be the same width 1.5" and would still get my 30" physical port size.

Just wondering is all. I have been searching the web for the last week or so and really cant find any information.

Each port of box 3 would need to be around the 30" not half length each.

Ok well I decided to change everything up. I was trying to use a box I had that was going to be 13.5 H 20 W and 11.5 D and I just couldnt get it designed without 2 bends in the port. So I am building a new box that will allow only one bend in the port so just a basic L port now.

Thanks for the responses.

If you want to see the box I built go check out my build thread in the link below. Page 54

Thanks
