I downloaded the beta version. Is that o.k.? Or is the Alpha one better?

I had to input the specs for my sub.

Does it look right? I'm not sure of the units.

I got the following graphs. What does it tell me? I don't see much difference in a larger sealed box vs the one I am currently using.

Advice? Am I using it right? After I got the initial graph, the only thing I changed is the box volume. Is thereanything I should change?

 

If you are still not sure, my program allows me to have 3 different amounts of poly fill (light, med , and heavy). I'll try to get to it this weekend for you.

 

Ok i3kc,
I played around on my program today. The best scenerio for the info you posted was for the subs to be in a sealed box .9 to 1.1 cuft ea with NO FILL! Every time I increased the "stuffing" there was a dramatic drop in the 35-45hz range. I was kind of surprised.
The other interesting thing was these subs would play very low in as little as .8 cuft. ea sealed. You mention that they are in 1.3 right now. That might be just a tiny bit too big.
I'm sure you will get 9 different opinions, but my software usually does a good job for me so here is my $.02
I hope it helps.

 

awesome, had no idea what EBP was but i learned something new and very useful tonight

 

Out of curiosity, what program do you use?

 

BassBoxPro. It is an older program (I bought it about 10 years ago)

 

i say you want deep bass? make a 4 cubic foot ported enclosure shared chamber for these 12"s and tune it to 30hz. then you can play chopped and screwed music all day and watch you car rattle to
