Looking for my Final Pair!!

Been through the high end maelstrom for over 30 years and although I have enjoyed the ride, I desperately want to find speakers that exude dynamics, tone and presence.  I want to be transported to the Village Vanguard where The John Coltrane Quartet are performing any night I desire.  I want to feel the timbre of his sax 🎷. When I close my eyes I want to be enveloped by the atmosphere of the space and awash with the impact and emotion being expressed by the musicians.  I don’t want to hear what the engineers hear after they mix a recording...I want to be in the studio when the tracks are being laid down!  So far, Tannoy Heritage Arden have come to my attention, Klipsch Cornwall IV’s, JBL S4700’s or perhaps Spatial Audio X3’s?  Help

@dave_b, 
I find the Fostex super tweeters work great with horns. Also, did you like the sound of the high frequencies on the JBL 4429's? Mike

@ditusa  The highs on the 4429’s were a bit gritty way up...just a tad dirty.

"" Practical example s of Intermodulation Distortion (IMD) measurements Intermodulation distortion can also be used effectively to evaluate crossover designs. If a transducer is excited with a fixed low frequency test tone, for example near resonance to cause large diaphragm excursions, and another test tone that sweeps up in frequency, the resulting distortion will indicate both amplitude modulation distortion and Doppler frequency modulation distortion.
The Doppler phenomena in loudspeakers occurs when a high frequency source is shifted by a low frequency. Look at the IM distortion for the fullrange loudspeaker with its single driver trying to reproduce the entire frequency Fig. 21a Harmonic Distortion components are attenuated by filter networks while 3rd range (Fig. 22). There is a lot of 2nd order difference frequency components remain the same level as the excitation frequencies, order IM distortion. This is quite audi- fi andf2 (assuming 100% distortion) 12 ble in the midfrequency range. If a chamber music duet with a cello and a flute is played through a single driver, the driver might cause the high frequencies of the flute signal to be modulated by the low frequencies of the cello signal. ""

That CW woofer is just terrible even that you said " low distortions ".
This appears to be a classic example of an Appeal to Authority, which is a logical fallacy. Anytime a logical fallacy is used, the result is false by definition.

While the topic he quotes is correct, it is unrelated tRaul's conclusion; the woofer in the Cornwall is of course crossed over. This prevents the Doppler Effect and distortion components this driver would make (which would otherwise show up at higher frequencies); instead the midrange horn is doing that job. Put another way, the woofer is not a 'fullrange loudspeaker' as described in the quote.
