[QUOTE="XxAndreaxX, post: 8518181, member: 669406"] Hi all, I'm about to port my sealed box, because I fear my speaker is not sealed friendly at all. It's the sundown X8 D4. The problem is that calculating the vent, I get crazy numbers. the box is 10Liters minus the size of the woofer. the form is very uneven so I can only calculate in Liters. Putting all the infos about the speaker in different calculators, and tuning port at 30-35hz, I get veeery tiny vents, but excessive long. here [URL="http://www.mh-audio.nl/reflexboxcalculator.asp"]mh-audio.nl - Vented System[/URL] for example, I get for a 4cm diameter port, 26cm port lenght. is that possible??? I got on another site for a 2,4cm diameter port, 40cm long tube I know the minimum size for the X8 is 20liters and mine is 10. but what do you think?? I never saw such a tiny port-hole [/QUOTE]
