Can the 260-388 port tube be used with the Karma speaker design?

Bought the parts to build the Karma Indignia speakers, which call for 1.5x8 in ports in a 0.38 cu ft enclosure. Can 260-388 be used instead? If so, what would be the length?
Asked by: Dexter
Yes this port tube should work just fine. Its diameter is 1/8" less than the design calls for, so to compensate for that you could decrease the port length slightly. 7.5" instead of 8" would probably do well. Overall this slightly smaller port will have almost no audible effect. It may increase port noise slightly, but It shouldn't be an issue.

Once you have your port length figured out is there a recommended procedure for "locking" the sliding portion in place? WeldOn 16 perhaps?
