the deminsions he said are the same. i just checked

Could you check the port? You should be able to measure the first part of the port by just sticking a tape measure down the port and catching the end and the last part of the port if you want to take your sub out. I'm betting the size/tuning are not correct though. Also, is there any 45s or bracing?

When ever you get the rest of the dims let me know and I will give you an idea of the air space and tuning.

You havent even tried this sub in different enclosures yet. So how can you say your dissapointed?

He means with how it is currently setup.

Well im willing to bet the enclosure is the problem.

It does seem that way right now, but I'm not 100% sure. That is why I asked for the dims just to double check and see what he is actually working with.

yes it has 45's and no bracing. i would take it out but im at work so i can't. let me go measure like you said.

45s will take the space down more, all though not a lot more. If you can get that port length we will get it figured out.

ok. i stuck a tape mesure down but their is a 45 there so the depth before the 45 is 15.5 and after the 45 is 17. the length of the port is 12.5 and 2" long

So far pro rabbits math is spot on as long as those measurements are external.

yes, they are

I come up with 1.825ft^3 tuned to 31-32(ish)hz with only 25in^2 port area.

That is assuming the sub displacement is around .16 or similar.

Also assuming the total port length is around 32.5 in long.

Ok, upon further inspection of the build log here the port is only around 16-19" long at most.

This means there is around 2ft3 and tunes around 38hz or higher. This is just a rough idea as there is no way to know with out the exact port length.

With that high of tuning no wonder it doesnt hit the lows well.
