You want to manually override that so they operate full-range and set the subwoofer's rolloff control to around 50 Hz..

I assume you ARE using a subwoofer?

I would ultimately like to end up with 7 CL-C's

It's not impossible, I guess, that in the TCOM is another coil effectively across the mid units to steepen the bass roll off.

What seems to be a series coil is perhaps there to tame the tweeters high frequency?

Normally a tweeter has it's own small series cap, eg, 5.6uF, to stop bass damaging it. The CDT would appear to not need such protection but I presume it needs DC blocking, hence in the Strada it has it's own series 40uF.

Normally a 40uF would be used with a mid unit to cross over at about 330 Hz. So that's very low for a tweeter.

Either way, to me, cross over less means no 'passive' components in series with the speakers, and the Ref 3.n do have passives in series with all the speakers.

The object in series with the CDT, that you refer to as a "Coil", is actually a "Transformer", and not a coil. It is used for impedance matching, and to raise the voltage of the signal to better drive the CDT. Due to the capacitive nature of the CDT, the capacitor in the CDT circuit doesn't effect the frequency at which the CDT functions, but rather its total output, so is not a traditional "Cross-over" component. However, there is a traditional cross-over between the woofer and mids of the 3.x series speakers. In the Classico speakers, the Mid-Woofers are driven wide open and the CDT still has its transformer.

Have you much experience with the Classico CL-C?

Thank you for any help

I don't know why it doesn't just say that on the official websites.

I just had a look at the schematic I sketched out and it shows a coil to earth of 0.5 Ohms; having a coil there before a tweeter is normal as it steepens the bass roll of before the tweeter. But then there is a series coil measuring 39 Ohms, which does not make sense unless there was a peak that needed dealing with, so a transformer does make sense. High voltage might also explain the arcing mentioned in a review of older speakers, if I remember correctly, perhaps the Ref 3.0? Do you know what the voltage scale up is?

My point was that you can usually hear adverse effects of components in the crossovers with speakers. So cross over less to me says, 'excellent, no smear from passives' and that's largely why I bought the Stradas. I can only presume that the capacitor will still have some effect on the sound quality in this CDT type of usage as a review stated that AG improved the quality of the caps between iterations of the models, an earlier one having an electrolytic cap in there. so can the caps in there be 'upgraded' to something that was too expensive for the manufacturer to afford, which is normally the case.

Thanks for confirming that the Classico have nothing in series with the bass / mid units. That makes them quite a bit more interesting to me

a. Have so little written about them so far, and
b. Are so unconventional in their design.

I hope they impress! My fear is that they'll be impressive in some "audiophile" way, but won't be satisfying in the long run. It's so difficult to audition anything nowadays! The story I've heard about them is that Gallo made them in response to dealer requests for something more conventional, and then he decided to sell them direct when the dealers failed to place the orders they said they would.

How do you CL-4 owners feel about them? I should have mine next week.

(P.S. It's funny, but we used the same PVDF material where I work for making underwater transducers. We put 300Vp-p across small cylinders to detect objects in the water)

Let them break-in for 80-100 hrs before critically listening to them. I know this will be hard, but they do open-up and sound betters after break-in.
