Speaker hookup question

[h=2]The original "ALK Universal" replacement crossover network for the Klipschorn, La Scala and Belle Klipsch as been reimplemented to create an affordable option for nearly any Klipsch based 3-way loudspeaker.
[/h] High cost is no longer a reason to turn the clock on your Klipsch back to 1975 with a newly built A or AA "Clone" from other vendors, when you can turn it forward with a modern design!

An economy network for almost any 3-way loudspeaker.

  • An affordable no-compromise design built with no-nonsense parts including low loss Litz wire inductors and German Audyn Q4 polypropylene caps. Virtually the same design and sound quality as the original Universal network. Much research has been done to ensure that the parts chosen for this design are comparable to those with big price tags. If you want more performance, look at an advanced design such as the AP12-500 + ES5800 set. High priced parts do not always translate to better sound but a correct design will!
  • A true 3-way network including a full crossover from squawker to tweeter at 4000, 5000 or 6000 Hz (bandpass) allowing the use of any quality squawker driver or the Klipsch K55.
  • The low frequency crossover is 1st order at roughly 400 or 600 Hz. The actual crossover frequency is acoustic and determined by the woofer and squawker driver and horn making it truly "Universal". It is compatible with the stock Cornwall, Heresy or virtually any Cornscala configuration.
  • Can be used in nearly all Klipsch based 3-way loudspeakers even those using wide range midrange drivers like the B&C DE85 at normal listening levels.
  • Enlarge A specially designed autotransformer having low DC resistance (0.382 Ohms) and tight coupling provides taps to allow squawker level setting changes by the customer. The choices will be 1 to 18 dB in 1 dB steps, Attenuation is selected without soldering by push-on terminals and without cryptic setting tables. The attenuation settings are clearly written by each tap in dB units. The normal setting will be 6 dB. This adjustment will also allow the use of 8 or 16 Ohm squawker drivers without modification. NOTE: Any transformer that is larger in size is a waste of money. It will handle 50 Watts of power without batting and eyelash with virtually no loss, That is already extravagant considering the power levels through the midrange in a Klipsch loudspeaker will generally be less than ONE Watt!
  • A stable 2, 4, 6 or 8 dB plug-selected L-pad is included to adjust the tweeter level.
  • Constant 6 to 8 Ohms resistive load impedance to the amplifier.
  • All networks are built in matched sets.

This is from Al K's website, although they measure 3.8 , the amp "sees" 8 ohms. This article is for his new universals and they show 6-8 ohms. The original universals showed 8 ohms. Can't find the writeup on those. He had a good write up on why they measure lower than the amp sees , but I can't find that either...
I have measured them before at 8, long time ago though..
 
So here is 2 different brands, both rated for 8 ohms, not that the meter readings mean much but it has to come into play. My custom crossovers are reading 4 ohms also.

yours have custom crossovers????

Pic of meter, hooked on the crossover connections....

I used Crites crossovers on my cornscala's but they are all close. I guess you would call that ESR??? Equiv Series Resistance????
 
I guess the next question is what is the frequency of the current generated by Mr. Fluke?

ESR is the resistance of a cap at a given frequency and voltage IIRC...
 
There is a lot going on at the crossover from the amp and all I was saying is I don't recommend pairing 2 speakers on one post. ESR would be around 2 ohms or less... Not good no matter how I look at it.
 
I guess not ESR but impedance from the meter which uses a dc battery and they are rated at the AC level (the speakers are).
 
Yep, a lot of stuff I don't understand yet. I'll find that article by Al where he explained why the amp would see 8 while it measured 4. It's on my backup drive , since my XP machine went tits up, I haven't moved a lot of files over..

Where's Joe when ya need him?? I'm sure he could shed light on what we're missing here....

The difference is impedance from a DC source (the meter) and an AC source (the amp).

Mr. Fluke uses a battery. I think they are using a known resistance, or voltage or current to display what you want to look at.

Yeah, and that can have a big effect on what we are trying to measure...
 
Perry, I gotta get up at 430, we'll take this up tomorrow, still a lot of stuff I'm not comprehending...later bud...
 
NOW I REMEMBER it's "DCR" DC Resistance. you'll see these guys selling vintage speakers and the'll show a meter hooked up showing the voice coil aint blown...

Not ESR.... My bad
