Okay, sounds like it works for you.
Keep in mind the spec'd sensitivity of the JLA 13W7, a variant is used in the home model, is about 87 dB and your Klipsch P-39F's are spec'd at 95dB.
While there isn't enough to say what exactly the specs are and that specs aren't everything, I wanted to show you this snippet from the Klipsch p-39F Stereophile Review
Looking first at the Palladium's voltage sensitivity, my estimate was 94.8dB(B)/2.83V/m, which is within experimental error of the specified 95dB. The P-39F is thus one of the most sensitive models I have encountered in 20 years of measuring loudspeakers—it will play very loud with very few watts. However, the speaker is not as efficient at low frequencies as you might expect; its impedance drops between 3 and 4 ohms in the lower midrange (fig.1), with a nasty combination of 4 ohms magnitude and –50° electrical phase angle at 80Hz. The three woofers do demand a significant amount of current to keep up with the horn-loaded midrange and treble drive-units. The impedance is significantly higher in the region covered by the latter two drivers, averaging 10 ohms, which means that the speaker will sound tilted-up at high frequencies when used with a tube amplifier having a high source impedance.
That being said, I only understand half of what is up there, and I would never stand infront of an audience and talk intelligently about it, but I have the notion that there
are some smarter people than me out there that could chime in and help.
I say all that to say. I think you have less than 8dB variance in sensitivity for a given/spec'd frequency and at time a lower sensitivity that allows your speaker all to work nicely together. On the other hand I have almost a 17db variance between my main speakers and my subwoofers for the spec'd frequency. I can go on with the fact that my LF comes from an eight foot folded horn. So there is a bit of delay, some what noticeable. I have compensated by lowering the output of the main speakers and raising the output of the subwoofer (not the LF level at the active crossover). I got it sounding the way I like it now.
What I recommend, is read a pro sound setup or something that has two or more separate arrays that support two different ranges of frequencies. I can tell you that my Klipschorns sound only second to the most recent rock concert I went to. I am sure in the texts they show the high directivity and output of horns, then output from a subwoofer array and then the art or the techincal polish it takes to get them to work together at the mix/soundboard position and the audience position.
