Elac Loudspeakers?

Ad,
So what IS the phase data for the Elac speakers? You can phrase it and post it as either a curve, Smith Chart, any other graphic, or just give the peak phase angle at a frequency.

Sorry, but I'm a #s kind of guy. Hi 80s sensitivity doesn't scare me. Watts are fairly inexpensive, though 'good' watts are by no means cheap!

Vacuum tubes typically don't like one kind of reactive load.....I simply don't know if it is capacitive or inductive so adding power to this kind of load is, if not futile, than more expensive than need be.

Just my strongly held opinion, but giving just impedance data is incomplete.
My Panels are pretty much straight across at just over 4 ohms with a substantial peak near the x-over. But....and this is more important, the phase angle is fairly benign, going from inductive to capacitive thru the x-over region at moderate angles.

Again, speaking simply from an engineering / electrical perspective.

Magfan:

In spite of being an engineer by original trade, I can't say that spend quite as much time analyzing empirical data associated with gear as I should. It's often confusing to the average, prospective client, but I do believe that this approach is very valuable assuming the testing is performed properly. Cudos...

That said, I was able to find an impedance graph in "Australian HIFI" magazine of all places. (The full written test can be found on the Elac Site.)

A PDF of the frequency response and impedance graphs can be found at:

Keep in mind that the test is for the Elac FS249. This is essentially the higher cost audiophile version of the 208 referenced by Mr Elusive but should behave similarly given the same basic design. The curves do indicate a dip in the 20-40Hz range and a significant dip again in the 60 - 200Hz range. I believe this would support my observed demanding nature of the speakers for high quality amplification, in spite of the fact that the sensitivity rating is fairly "friendly".

Thanks for the technical prospective. It's a reminder that we should consider more than one prospective on how we evaluate products in our business. BTW: My experience with tube gear with the Elacs supports your assumptions as well. I have not had good luck driving Elacs with the several lines that I carry.

Thanks

My apologies! .... KUDOS! ( I apparently I'm better at Audio than spelling.)

I used to have a pair of Elac CL142 floorstanders with 4ohm imp. As it's already been said by the others, it's very revealing, so it's hard work trying to put the right system together. For me it was difficult to get the bass right because my was entry level CDP didn't have much bass, and my amp although solid state, not quite powerful enough to drive Elac.
Basically Elac loves lots of power, I heard that a brother brand called "Linear Acoustic" goes well with Elac.
If money is no object, Elac really does compliment high end equipment, like MBL for example. I don't recommend CDP+ amp with bright sound.

Indeed, good measured performance.
Also, if I read the graph correctly, the highest phase angles occur at or near impedance peaks. This may help, but still and all, 60 degrees is pretty brisk and corrosponds to a power factor of 0.5 (Cos 60) which means that at that particular frequency, only half the amplifiers power is available to do actual work. This occurs at a frequency range in which there is substantial musical energy.
In general, I prefer the Smith Chart for this presentation, since you can easily see displacement from the horizontal axis as phase angle data.
As a matter of fact, simply speaking from a measured / electrical aspect, this is indeed a somewhat demanding speaker. Good watts are a must.

If you were a Chemical or Mechanical engineer, you have a good reasonable excuse for not knowing about PF and phase. I work with a bunch of EEs, in a semiconductor manufacturing enviroment. At least one of 'em NEVER forgot anything he ever saw in a math class@!!
But the math is pretty straightforward. Most audiophiles get hung up on impedance and you can't talk 'em out of it!
I used to drive a Baracudo.
