Peter P. Posted September 2, 2023 Share Posted September 2, 2023 With such small amperage fuses being used, it's a wonder there's a market for all those heavy duty, oversized speaker cables. Have I just exposed a conspiracy? 😃 2 Quote Link to comment Share on other sites More sharing options...

I am curious which K-horns came with 1.25 amp woofer fuses? I bought my Khorns new in 1987. Original fuses are 1.25a and 2.5a. When I converted to Al's Extreme Slopes, the 2.5a fuses where removed from the circuit path Quote Link to comment Share on other sites More sharing options...

Have I just exposed a conspiracy? 😃 I would have thought that it would be the other way around. With such sensitive speakers, cables only need to be 22 awg. I have a spool of telephone wire around, I'll have to try that some day. That is if I ever get the Khorns working again. Otherwise, I'll just set them down by the curb with a "free" sign on them.

OO1 Posted September 2, 2023 Share Posted September 2, 2023 joking aside these ALK's were connected to a surge protector and they still failed , buy new crossovers from klipsch , they can handle transients 1 Quote Link to comment Share on other sites More sharing options...

The only thing Klipsch is the cabinets and woofers, I have BMS mid-range drivers, B&C DE-120 tweeter drivers and ALK's Extreme Slope cross overs. I'll be replacing the APC ups with something more substantial and work with Al on getting the situation resolved. No more listening to music during a thunderstorm.

Deang Posted September 2, 2023 Share Posted September 2, 2023 We use APC at work on our network switches. You sure the unit just didn’t fail to do its job? Short of a direct lightening strike - should have protected your amp. Which unit do/did you have? Quote Link to comment Share on other sites More sharing options...

Yeah; surge protectors can fail and I know of no way to test them for reliability. Also, a surge protector is not necessarily a SPIKE protector as well. A quick response time, the ability to handle a high number of Joules (energy) and the ability to clamp the incoming voltage to a safe level, are other specs to look for on the package. Could be whatever fried his speakers exceeded the capabilities of his surge protector even though the surge protector was within spec.

We have a lot of power outages-surges here in this part of TN. I live in North Ga, at Lake Lanier and thunder storms are common in the late afternoon early evening. I kind of figured I was covered with using a APC ups. When I get my woofers working again, I'll double up on protection. Maybe a Furman Elite DM plugged into a Tripp Lite ISO Bar. Later in this thread someone mentioned using an ac/ac transformer to block spikes. I'd like to know more about that. 1 1 Quote Link to comment Share on other sites More sharing options...

Could be the fact that I have a 200 watt per channel McIntosh connected to speakers rated for 100 watts. I don't think the speakers are 'Fried', maybe a capacitor or two on the board that feeds the woofers. ALK suggested 5 amp fuses and I just received them but I can't see that solving the problem. I'll give them a try but if that doesn't work I'll replace the capacitors next. Quote Link to comment Share on other sites More sharing options...
OO1 Posted September 3, 2023 Share Posted September 3, 2023 Not at all A 200 wpc amplifier is recommended for headroom and lower distortion for a 100 watts rated speaker , a khorn can handle peaks of 400 watts for short periods Quote Link to comment Share on other sites More sharing options...

You'd be using sign language to communicate after listening to them at 200W/ch.! Quote Link to comment Share on other sites More sharing options...
Peter P. Posted September 3, 2023 Share Posted September 3, 2023 You should be able to measure the board components with a voltmeter. And you should be able to verify a voltage output at each drivers' terminals. If you have another pair of speakers, even a bookshelf pair, I'd hook them up to the woofer outputs of the Klipschorn. If you get decent sound, albeit frequency limited, then it's not the crossovers. Quote Link to comment Share on other sites More sharing options...
