evan judd Posted November 20, 2009 Share Posted November 20, 2009 I recently got a pair of KSF8.5 one had port ring and the other one had an open port where the port belongs. I am guessing that this effects the accuracy and detail of the bass frequencies coming from these speakers. Does anyone know the diameter, and length of the tubes, so I may be able to fabricate something? Quote Link to comment Share on other sites More sharing options...
evan judd Posted November 25, 2009 Author Share Posted November 25, 2009 nobody has any info? if someone has a pair could they kindly just place a tape measure inside the port and measure its length? It would be a great help thanks, Evan Quote Link to comment Share on other sites More sharing options...
Klipsch Employees Trey Cannon Posted November 25, 2009 Klipsch Employees Share Posted November 25, 2009 If you will post a pic of the one you have, I will look around the lab to see if we have any that will work. If you have a hole where a port was the speaker will not work as it should. If the port is just a "ring" that makes the hole look good, then the tunning of the speaker will be ok, but the port noise will be more noticable.

evan judd Posted November 27, 2009 Author Share Posted November 27, 2009 What should I post a pic of the port ring? the port hole? or the whole speaker? I was told that there was originally a port tube (cardboard) with one of those plastic ring one either end. The length of the cardboard tube is unknown.

Klipsch Employees Trey Cannon Posted November 30, 2009 Klipsch Employees Share Posted November 30, 2009 the plastic on each end we call a port flair. It helps with the noise that comes from the port at high volumes. I will try to find the length of the port. we have a box of old flairs. There may be some in it that will fit your speaker. Measure the other one and give me that data. I will look for you. Quote Link to comment Share on other sites More sharing options...
evan judd Posted November 30, 2009 Author Share Posted November 30, 2009 Thr port flair where it fits flush to the outide of the cabinet is approximately 4 13/16 inches. inside diameter is a little harder to get because there is a ridge where I am asuming the port tube itself would go. The inside diameter on the back of the flair is approximately 3 1/4 inches with the ridge leaving an allowance for and 1/8 inch thick wall on the port tube that I would estimate inside diameter at 3.00 +/-. The length I do not know and and the inner port flair I do not have either. I would be probably be like the one that fits to the cabinet but a smaller overall diameter. The whole tha is left in the cabinet after the flair is taken out measures approx 4 1/4 inches Quote Link to comment Share on other sites More sharing options...
evan judd Posted December 2, 2009 Author Share Posted December 2, 2009 Would it help if I took a picture or pictures of it? If so, how and where would I post those pics? Quote Link to comment Share on other sites More sharing options...
