you can completely cover the port. seal it up with like a piece of wood with caulk and if you dont like it just take it off. and do you any deadner in the box , you can just use pillow stuffing.
Whelp, the box is based off of Rockford's specs. I am not too familiar as to what all the numbers mean, but here is how the speakers are built.
1 cu ft 3" port at 13.25 inches long
Here are the #'s on the documents FB = 35Hz FS = 27Hz QTS = .49 VAS = 2.66cu ft
I don't want to rebuild the box, so I was hoping to modify this design to give me a better sound.
Say Mike5211, I thought about covering the port to make it a sealed box but the enclosure would be almost twice the size needed. For ported = 1 cu ft for sealed - .65 cu ft I may have to try it anyways to see what I can get.
I would just try it no harm could be done and get the sound deadner. You never know could sound great even if it is to big.
do you have a low pass filter on your amp it should be set I think 27 or lower if can even go that low because your problem may also be that your speaker is putting out higher frequencies then your box is made for.
