Bass box pro 6 calculations problems?

Good evening everyone. I have had this program for a few years and now starting to use it. I have been reading the book it came with. It keeps giving me boxes that are to small for the port to fit and keeps telling me the box is to small? I try and change the box volume and it keeps changing the f3 hz that I put in it? I try and let it calculate the best response but the frequency graph is so out of this world. No matter what I change the port length the filling in the box the f3 hz or the box size. Parts express modes a box using bass box and got a flat frequency responded but the box is still to small for the port? I feel I wasted my money and wish there was a box program that is more fixable and let's me a just the box size to the taste that suits me? Sorry for the rant I have been working on this problem for a few days now. Can this problem be fixed or is it the program? Please help. Jeff

You can improve the upper bass response by using it in a 3 litres vented cabinet ( vent 1" by 1"), Fb=107 Hz, and see how and whether it will sound ok.



Hello. So what box program are you using? I did the 3 liter box and 1 inch by 1 inch port in the bass box pro program. A little better but not the best? I also got a e mail back from the company super quick which is nice. So I have tried and done everything I have been told ? Still scratching my head? So here is the screen shot from what P.E. sent me? And the one I just did on the main screen of my computer. So am I missing something here?

Hi Jeff,

perhaps you are missing the point that a high Qts driver is not meant to be loaded optimally in a vented enclosure but if you prefer to boost those frequencies, you can do that. Of course, you will decide for yourself if that makes sense once you try it out. Simulation programs are very hepful in visualizing such technicalities, not more than that. I use an excel spreadsheet "Woofer Box and Circuit Designer".

Okay gotcha now. The owner from common sense only has designs for ported boxes and a few open baffles on his web site.
I will have to maybe look a sealed enclosure. Thanks for your help. Thanks for letting me know what program you use. Cheers Jeff
