john toon Posted April 12, 2014 Share Posted April 12, 2014 The other night I had the Khorns cranked up a bit and noticed that I popped the fuses in the bass sections. I may have had them at a ridiculous volume but I think they should have been able to handle it. would it hurt to bypass the fuses or simply put larger fuses in them. Do all Khorns have fuses inline? I don't listen at that volume level too often but I do crank them once in awhile for the non-Klipsch owner to show them what their missing.

The Dude Posted April 12, 2014 Share Posted April 12, 2014 Following this thread out of curiosity, I don't own Khorns or anything that has fuses in the network. But I thought the fuses were for tweeter protection. I am interested what other may have to say. Sorry I am of no help. Quote Link to comment Share on other sites More sharing options...

Deang Posted April 12, 2014 Share Posted April 12, 2014 You may also have been over-driving your amplifiers. If you have aged induced hearing loss, or have damaged your hearing, then you will need more volume to achieve the same effect as compared to someone who hears normally. To blow those fuses means you were listening at insane levels (or is that an insane guy with an attenuator in his hand : ) Quote Link to comment Share on other sites More sharing options...
john toon Posted April 12, 2014 Author Share Posted April 12, 2014 id say it was close to rock concert levels. I'm a musician so hearing loss may have a play in that. Quote Link to comment Share on other sites More sharing options...
Deang Posted April 13, 2014 Share Posted April 13, 2014 Do you have an SPL meter? How much power are you driving them with? Quote Link to comment Share on other sites More sharing options...

Max2 Posted April 13, 2014 Share Posted April 13, 2014 Is there any technical loss sending the signal through a fuse? its seems like it would just be another variable to add in the pathway. Quote Link to comment Share on other sites More sharing options...
ssh Posted April 13, 2014 Share Posted April 13, 2014 Don't try bridging the fuse holder, if that is what you're hinting at. If you do, you'll most likely have another DIY project on your hands. I've blown fuses once on my Khorns, and I was sober, but working in the backyard. SSH Quote Link to comment Share on other sites More sharing options...
ricktate Posted April 13, 2014 Share Posted April 13, 2014 You did not say what size of fuse you blew??? Rick 1 Quote Link to comment Share on other sites More sharing options...
pzannucci Posted April 13, 2014 Share Posted April 13, 2014 I would also check your amp out. I had K-horns to some ridiculous level with my Bel Canto REF-1000s. Never bothered anything except my neighbors. Quote Link to comment Share on other sites More sharing options...
john toon Posted April 14, 2014 Author Share Posted April 14, 2014 Some music is more tolerable at higher levels than others, we were listening to "I stand alone" by god smack.... they are 2.5 amp fuses and I'm using a denon 4308ci which is 140 watts ch. I don't listen to those levels very often BTW. Quote Link to comment Share on other sites More sharing options...
ricktate Posted April 14, 2014 Share Posted April 14, 2014 A 2.5 amp fuse I would say something wrong with amp I only got 24 watts going to my Ks and you can not stay in the room at half volume. Rick Quote Link to comment Share on other sites More sharing options...
Khornukopia Posted April 14, 2014 Share Posted April 14, 2014 You probably have the AK-2 with this fuse panel and low frequency crossover components that are both on the K-horn bass bin door. Some owners install fresh new fuses every ten years, just for fun. You probably just need new fuses, available from Radio Shack. Quote Link to comment Share on other sites More sharing options...

001 Posted April 15, 2014 Share Posted April 15, 2014 (edited) These are the replacement fuses that matched the old fuses. #270-1022, #270-1024 please read the "dope from hope" article above.... the fuses pictured are the WRONG fuse for speaker or amplifier protection! no offense to you khornukopia. i have mentioned this before on here, speakers require "fast blow" fuses if they are to be of any protection to speakers or other delicate electronic equiptment. the slow blow type will almost definantly not blow fast enough to stop damage to the device down stream. if anyone is using slow blow you should replace them ASAP. the same place that has slow blow at these ratings should also carry the fast blow.

twistedcrankcammer Posted April 15, 2014 Share Posted April 15, 2014 klipschfancf4 is correct. The correct Radio Shack part numbers are 270-1008 for the 2.5 Amp Fast-acting fuses. I haven't seen any 1.25 Amp fuses in years. Radio Shack sells 1.5 Amp Fast-Acting fuses part number 270-1006 which I have used successfully.

Khornukopia Posted April 15, 2014 Share Posted April 15, 2014 (edited) Thanks for bringing this to my attention. No offense taken, we want this forum to be a source for reliable information. I had used the old fuses as my buying guide, but they must have been the wrong ones. I will edit the fuse numbers from the previous post. I have added this picture of the input fuse panel on a 1983 Klipschorn with an AK crossover. I just read that the GBB type fuse is classified as a VERY Fast Acting Fuse, compared to the AGC type Fast Acting Fuse. I learn something new every time I visit the Klipsch forum.

001 Posted April 15, 2014 Share Posted April 15, 2014 just trying to help. the slow blow fuse wont cause any problems untill the moment when something that would damage the speaker gets through for too long, the tweeter is usually the easiest to damage, but the mids & woofers can get damaged too when that situation occurs. some people just bypass the fuse & use common sense to not overdrive the speaker, & thats fine. but for times like extreme surges or shorted amps etc, the fast blow is there to do whats its name implies. im sure slow blow fuses are better than nothing, but its a good idea to have the right one in there just incase. i blew the woofer fuse in one of my k-horns a few weeks ago too while playing some loud bass heavy music, my local home store (menards/home depot) had them for half the price of radio shack.

Guest Steven1963 Posted April 15, 2014 Share Posted April 15, 2014 (edited) I'm no expert, but I tend to agree with what others have said: check your amp - you may be sending bad signals to the khorns. From what I remember (and I could be wrong), most speakers are blown (or blow fuses) by bad power being sent to them by the amp than by overpowering them.
