still in the dilema of my PORTED ENCLOSURE

[BASS OUTLAW]

the manual prefer an enclosure of 1.75 cuft , and every 1 says for SPL , i better go for , 3.4 cuft or 4 cuft , thats means width 50 cm , height 50 cm , length 50 cm ,
isnt that too big for single TS-W121SPL ??

and for the port, the manual prefer 4"x6.5" , thats the area right ?? ok how should i know how long the port should be ?? ( pluse i increased the total volume of the enclosure , does that mean i should increase the port area also ??

bigger box, more port area.

I have a feeling that your manual means you should have a 4" port that is 6.5" long. They usually use round ports.
