Dreamweevr Posted December 29, 2015 Share Posted December 29, 2015 (edited) I recently traded a pair of Bose 151 indoor/outdoor speakers for these vintage Klipsche. One of the speakers on the backside is busted, what should I replace it with? They sound great even with a busted speaker but want to replace both of the backside ones.....the only legible writing on the tag is KG4 1985 Thank.....

TasDom Posted December 29, 2015 Share Posted December 29, 2015 KG4 is the model number. If the damage you are talking about is the dented dust cap, it will not affect the sound. The specs are awol right now but here's the info page. http://www.klipsch.com/products/kg-4 Quote Link to comment Share on other sites More sharing options...
TasDom Posted December 29, 2015 Share Posted December 29, 2015 I see the hole in it now Quote Link to comment Share on other sites More sharing options...
Mallette Posted December 29, 2015 Share Posted December 29, 2015 Someone will have replacement suggestions. However, you can also have the original reconed. Freeman Tuell in Dallas is highly regarded for their work. The Kg series are classics and were designed by a person PWK was impressed enough to allow his initial "g," on the speaker.

Mallette Posted December 29, 2015 Share Posted December 29, 2015 BTW, welcome to the Forums, and thank God you got rid of the Bose before joining. That was one heckuva good trade! Dave 3 Quote Link to comment Share on other sites More sharing options...

wvu80 Posted December 30, 2015 Share Posted December 30, 2015 (edited) KG4 is the model number. If the damage you are talking about is the dented dust cap, it will not affect the sound. The specs are awol right now but here's the info page. http://www.klipsch.com/products/kg-4 Here are your specs compliments of the Australian Klipsch web site: http://www.klipsch.com.au/kg-4/details +++ One of the speakers on the backside is busted, what should I replace it with? They sound great even with a busted speaker but want to replace both of the backside ones.... I'm not sure anyone has addressed this yet, but the speaker drivers are all in the front. The 12" round thing in the back that has a hole in it is a passive radiator. There are no electronics or wires attached to it. http://www.centerpointaudio.com/PassiveRadiators.aspx Edited December 30, 2015 by wvu80 Quote Link to comment Share on other sites More sharing options...
mattSER Posted December 30, 2015 Share Posted December 30, 2015 Yeah, I would just look into patching it. Get it airtight and you should be good to go! Does anybody know the name of the KG series' designer? It read it somewhere once, forgot what it was. 1 Quote Link to comment Share on other sites More sharing options...
Marvel Posted December 31, 2015 Share Posted December 31, 2015 Thar 'speaker' on the back is a passive radiator, and works the same as a port or vent on other models. It is there to tune the low end response. If you don't care about looks (they are on the back), you can repair/plug the hole with a small bit of pva glue, silicone glue, rtv... If there is a tear, you can remove the passive from the cabinet and use a small bit of tissue paper/cigarette paper with glue to patch the tear.

Bruce Also, if you need a little more robust backing, apply the thinnest rubber electrical tape you can find and coat the taped side of the tear and the front side of the tear with the adhesives mentioned above. If I remember correctly, the surrounds on the KG4 were natural rubber, so a bit of rubber tire cement should do nicely. You want to use as little tape as possible, applied as uniformly as possible or it may buckle in that area when it rolls.
