klipschhornfan Posted April 25, 2019 Share Posted April 25, 2019 Is the cabinet back meant to be air tight? If so, is there any gasketing tape you would recommend that goes between the cabinet and the cabinet back? Thanks. Quote Link to comment Share on other sites More sharing options...
carlthess40 Posted April 25, 2019 Share Posted April 25, 2019 Yes it should beA thin rubber tape will be fine. If it’s to thick you will need longer screws Dollar for dollar Klipsch has no equals Name one other speaker company that can build a speaker and keep working like new after 45 plus years of service.

larryk Posted April 25, 2019 Share Posted April 25, 2019 I used some 3/8" rubber window seal from Home Depot to seal the backs of my Cornwalls. Only costs and there was a definite improvement in sound after installing. 1 Quote Link to comment Share on other sites More sharing options...
carlthess40 Posted April 25, 2019 Share Posted April 25, 2019 Well with the H1’s and H2/3’s they need to be sealed very well as the woofer has very little movement ability or the X max measurement so it highly relies off of havei g a very well sealed cabinetDollar for dollar Klipsch has no equals Name one other speaker company that can build a speaker and keep working like new after 45 plus years of service.

klipschhornfan Posted April 30, 2019 Author Share Posted April 30, 2019 I have problem finding window seal thin enough to seal the gap between the main cabinet and the cabinet back. Does anyone know a good source for this type of paper thin window seal? Thanks. Quote Link to comment Share on other sites More sharing options...

carlthess40 Posted April 30, 2019 Share Posted April 30, 2019 Go to the audio parts store and get some cork gasket and seal it with that or see if they any rubber that will workDollar for dollar Klipsch has no equals Name one other speaker company that can build a speaker and keep working like new after 45 plus years of service.

Answer NO ONE !!!!!! Thanks! I will attend to the back sealing for my new-for-me Heresys. One has a speaker terminal loose in a too big a hole, badly. I need to fill gthe hole and put in a new through-the-cabinet speaker terminal, like brass screws I put in a home built speaker I made years ago! VERY well sealed! John Kuthe...

klipschhornfan Posted April 30, 2019 Author Share Posted April 30, 2019 Do I need longer wood screws with this tape or the stock screws are OK? Should I add some of this tape to the seal the driver surrounds on the inside? Quote Link to comment Share on other sites More sharing options...
jimjimbo Posted April 30, 2019 Share Posted April 30, 2019 You won't need longer screws. Sure, you can add some of this tape to the surrounds, no problem. Quote Link to comment Share on other sites More sharing options...
JohnKuthe Posted April 30, 2019 Share Posted April 30, 2019 I've got some industrial double sticky 1/16" foam tape that I'll use to seal up my Heresys, after I fix that bum speaker terminal hole! And I'm gonna use longer screws when I finally seal mine up just because a few of the stock screws seemed a little well-used, if ya know what I mean! John Kuthe...

JohnA Posted April 30, 2019 Share Posted April 30, 2019 The thinking from Klipsch was/is that they were "tight enough" without a gasket. However, a gasket cannot hurt, unless it glues the back on. be sure to seal the ends of the screw blocks where they almost touch. Use a glue stronger and more durable than silicone.

mark1101 Posted April 30, 2019 Share Posted April 30, 2019 I use the same stuff Jimjimbo and Windashine mention. Works excellent and compresses to almost flat. It is perfect to seal a Heresy. I used it on the slant monitors I recently acquired. Quote Link to comment Share on other sites More sharing options...
glens Posted May 1, 2019 Share Posted May 1, 2019 I'd say that so long as the woofer, when (appropriately) pushed backward and held for a moment, is not delayed in returning when released, and no "air movement" sounds are detectable from the would-be-sealed locations, the boxes are air-tight-enough. Not that it would hurt to go the extra mile sealing them up, but it doesn't really gain anything past a point. Quote Link to comment Share on other sites More sharing options...
Tony Whitlow Posted May 1, 2019 Share Posted May 1, 2019 Screw the backs down tight. They’ll be fine if a gasket were required PWK would have used one.Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
DizRotus Posted May 1, 2019 Share Posted May 1, 2019 Gasket material is not required. Nevertheless, I always use it when replacing the backs on Klipsch Heritage -- even ported Heritage. Similarly, the woofers in most Heritage have 8 mounting holes, but Klipsch used only four mounting screws. Are eight screws required? No. Are eight screws better? Yes. Is thin gasket tape, as referenced above, better? IMO, yes. Quote Link to comment Share on other sites More sharing options...
