Box is too large?

[Dawid]

Hello there everyone.

I've recently bought an Audio System X-ion 10 Plus subwoofer without any enclosure. I asked some friend to project a box for this sub.

The problem is, after I had built it I realised, that it's (I think) a little bit too big. I have found a manual, and it says, that vented box should be 35 litres and 40Hz. Mine is 44L and 37,9Hz.

Does anybody know this subwoofer? Could you tell me if I should make another, smaller box? And finally, if I should build smaller box, please tell me how to keep this 37,9Hz tuning?

Those are schematics for my current box (lenghts in milimeters):



Oh, and sorry for my poor English. I'm from Poland.

Have you tried the subwoofer in the box yet? Hook it up and test it. Don't give it too much power in case that box makes it want to exceed maximum excursion.

Yes, I have tried it. The speaker seems a little bit weak. Excursion is high, but bass is not as powerful as expected. Additionally the gain knob must be at about 70% to hear good bass. Headunit is set properly.

For this speaker I've got Ground Zero 2.500TX

Box actually looks okay for a stronger sub. However the sub you have is more for sound quality so the port needs to be slightly smaller, the airspace should not affect it as much as the port will. Is the subwoofer in a trunk and what direction is it facing?

1.55 tuned to 41. What music are you listing g to?

 

[Dawid]

Yes. The sub is in Seat Leon's trunk facing left side of it. The port is closer to the trunk door.

I listen mostly fast electronic music, but sometimes I like to play some rap or even something like Modern Talking //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Edit

What do you think about this box? Would it be better? 30L, 40Hz:
