He was refering specifically to this request, about creating a hump in the response over a relatively broad range of frequencies:
With a vented box, you can't really make such a broad hump, but it should sound fine if you tune for a flat response over the 30-100Hz range. HTH, David.

Sorry to revive this, but I'm planning to build subs with a single BMS 18N862 in a 200L cabinet tuned to 30Hz, they will be crossed over at 100Hz. Are you saying that this speaker tuned to 30Hz will give a bad respons in the upper 70-100Hz range? |

Exactly Low Low with minimum effort would equate to what is shown below... Don't expect to get such as response with high electrical damping drivers. Best Regards, |

That's cool bro. I spent hours trying different port sizes. You're right. This was too small. Its now more then double that size.the problem is.. different drivers need different size port.

Just because you got more boxes that don't make you a man....

did not want to offend you!!!
i just assumed the ported backchamber is to add a little bit to the low end, and the port looks really small for that purpose on the picture. but if it works the way it should, everything is fine! |
