Groomlakearea51 Posted July 21, 2007 Share Posted July 21, 2007 Stock 85+ Klipschorns come with a 4 amp fuse (found out this morning when I blew one.... Bad banana's...). Replaced, all ok.... But got curious.... Need opinions on the primary fuse. Should they be left at 4A or maybe 3, 2, etc,? Any ideas, thoughts, "best practices"? I also use a fast 2A inline on my other earlier Klipschorns, Cornwalls, Heresy's etc. I'll probably throw in an inline 2A on these, but before I do, was there some technical reason Klipsch use a 4A on the later Klipschorns. Also, the woofer fuse is a 1.25A, any known reason? Leave it alone? Change it? Quote Link to comment Share on other sites More sharing options...
Erland Posted July 21, 2007 Share Posted July 21, 2007 All I can tell you is what's recommended in the Alkeng ES xo's. The woofer fuse is a 1.5A fastblow.I use no fuses in the other xo's. Regarding the 4A I can not tell, as I never had the stock setup in my horns. Regardless 4A sounds a lot? Quote Link to comment Share on other sites More sharing options...
Guest " " Posted July 21, 2007 Share Posted July 21, 2007 my 1985's had AK-2's. based on the attached schematic...you have the wrong fuses. ak-2 fuses should be low section 2.5 amps high section 1.25 amps AK-2 crossover.pdf Quote Link to comment Share on other sites More sharing options...
Groomlakearea51 Posted July 21, 2007 Author Share Posted July 21, 2007 Strange... The terminal panel is clearly marked 4 amps; that being said the high section is the 1.25 amps. Possible change mid-stream with the AK-2's? Quote Link to comment Share on other sites More sharing options...
Groomlakearea51 Posted July 21, 2007 Author Share Posted July 21, 2007 OBTW; I have some 2's and 3's if the consensus starts pointing in that direction. Quote Link to comment Share on other sites More sharing options...

Possible change mid-stream with the AK-2's? so is this one of those 2.5 slow blow or 4 quick blow gigs? here's the ak-3 and it also uses 2.5 in the lf and 1.25 in the hf section.

Groomlakearea51 Posted July 21, 2007 Author Share Posted July 21, 2007 It was a quick blow 4.... Real Quick........ 0.01 second Bzz.... etc. and that was it... They sound fine now, tested everything, doin a little 10cc's Dreadlock Holiday at about 10 watts......... Perfect... Very lucky... Spent all afternoon replacing every banana I had......

Guest " " Posted July 22, 2007 Share Posted July 22, 2007 that makes sense...a 4 amp quick blow vs a 2.5 amp slow blow/ just make sure you don't put a slow blow 4 amp in there. Quote Link to comment Share on other sites More sharing options...
Groomlakearea51 Posted July 22, 2007 Author Share Posted July 22, 2007 Absolutely!! Fast blow fuses only. Played the pair at moderate volumes with same amp for 8 hours, no further problems. Pulled the "offending" fuse holder, no heat, etc. Checked autoformers, etc. All ok, nothing "hot", etc. Quote Link to comment Share on other sites More sharing options...
DrWho Posted July 22, 2007 Share Posted July 22, 2007 4A into an 8ohm load is about 128W. A 16ohm load is about 256W. Depending on where the fuse is in the network, 4A should be fine as long as its a fast blow. The Khorns are rated for 150W input aren't they? EDIT: oops! (calculator malfunction) Quote Link to comment Share on other sites More sharing options...
BroMike Posted July 22, 2007 Share Posted July 22, 2007 4A into an 8ohm load is about 64W. A 16ohm load is about 128W. Depending on where the fuse is in the network, 4A should be fine as long as its a fast blow. The Khorns are rated for 150W input aren't they? Man, apparently they have gone and changed Ohm's law on me again...I hate it when that happens. Michael Quote Link to comment Share on other sites More sharing options...
colterphoto1 Posted July 23, 2007 Share Posted July 23, 2007 there once was a contest for roadies who could rewire a Crown amp to put out 500 watts using only a Ding-Dong wrapper. Quote Link to comment Share on other sites More sharing options...
HarryO Posted July 23, 2007 Share Posted July 23, 2007 "there once was a contest for roadies who could rewire a Crown amp to put out 500 watts using only a Ding-Dong wrapper." Cool !!! As long as they didn't start out with OVER 500 watts. Better living through chemistry ya know. Harry Quote Link to comment Share on other sites More sharing options...

I been using tin foil 34 years[:^)] Guess that would be considered slow blow? Must be that my ultra-conservative SPL's have saved me.[] To beat BEC to the punch, I had one little boo-boo with a K33. Some use 8ga speaker wire, and install an in line fuse with a filament half the size of a human hair. Just love it. Terry Quote Link to comment Share on other sites More sharing options...
BroMike Posted July 23, 2007 Share Posted July 23, 2007 Tin-Foil hats just don't count in this discussion...especially when what's under the hat is well past blown. As to the fuses.....it's not the appearance but what's truly INSIDE that matters. When did you last see a human hair? -BroMike Quote Link to comment Share on other sites More sharing options...

HarryO Posted July 24, 2007 Share Posted July 24, 2007 I like the hat. Problem is my scalp is already reflective enough. Maybe if I design it with the "shiny" side on the inside. I wonder if I install reflectors around the ears will improvements be noticed on the HF and LF? Do I have permission to "tweak" your design? I desire no infringement issues here.

IB Slammin Posted July 24, 2007 Share Posted July 24, 2007 Harry, I know about reflections. IB Shiny even inside a building. I am told that the top of my head can be seen from the Space Station. Smile. tc Quote Link to comment Share on other sites More sharing options...
