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?
Yes, I have (3) MFW's stacked in a corner (only place available) crossed over @ 80Hz. The CL-4's will produce bass below 50hz, it's just a much lower level than the rest. The last time I calibrated them was just after~100 hrs of break-in. I may try calibrating them this weekend and see if there's a change after 300+ hrs.

Hey, excellent information Barry. Thanks smile.gif

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 smile.gif

Barry or any Classico owners

Have you much experience with the Classico CL-C?

I am looking at 3 of these for LCR's with the left and right vertical.
Bill Fried from Gallo told me the CDT is very easy to rotate.
I might have to help the bottom for stability.
My concern is the CL2 might not have enough and the CL3
does not fit well in my room.

I have 2 quality subs in the room so bottom end is not an issue.

How about melding the Classico's with old school Dipoles?
I have 4 Energy RVSS for side and backs that have been
working well for 15 years.

Thank you for any help

Steve
post #2645 of 2938
I currently have (3) CL-4's (LCR) across the front. I have dipoles on the sides and (2) center channels as rears and they are not Gallo. For HT duty it works, no complaints. But I would eventually like to replace the surrounds all with CL-C's.
post #2646 of 2938
You have 3 CL-4's as LCR?

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

Yes, (3) CL-4's across the front. When the sound pans across the front is just absolutely seamless! I never did like having the L/R different than the center. I would have love to have replaced all my speakers, but needed more $$$. I thought about using CL-C's too, but I was hoping to run the L/R's full range for stereo. I guess my room is just a little too big (20x23x8) and those CL-4 woofers just can't pressurized the room. Of course having (3) 15" subs ...

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 coil you're seeing is an impedance matching transformer.

post #2651 of 2938
Has anybody audition and compared the AG CL-3 with the Totem Acoustic Sttaf? I have auditioned the Sttaf and really like the airy laid back sound, but they are priced fairly high and you can't do an in-home audition with them.

Sorry Ian, I don't know what the voltage is after the transformer, and I understand your point of view regarding passive components as well... Very often, less is more wink.gif
post #2653 of 2938
Hi there
Wanting to upgrade my speakers and was wondering if anyone has experience running 3.5's on only 45w NAD amp (not tubes)? Guess I'm old and remember when that shook the house... 100+w just seems inefficient to me.

If I remember correctly, I read in an article that Anthony said the voltage is limited to a maximum of 1200 volts and the driver can take 1500 without damage.

Cheers,
OldMovieNut
post #2655 of 2938
1200 volts. And people were taking the grills off eek.gifsmile.gif
post #2656 of 2938
Actually to destroy the tweeter you need to apply 5200V. Here is the source (6moons).

cau, d.
post #2657 of 2938
Thanks,

I'd read and forgotten all that.

"Did you know that the only way to destroy this tweeter is by applying 5200 volts to it? Even then it would take a microscopic tear through the membrane to cause destructive arcing. We limited the matching transformer on the CDTIII to 1200 Volts—which would represent an input of well over 500 watts— so this really is a bullet-proof design.

That's good know as I last year melted a pair of tweeters with some random spuriae that came on it's own from the computer.

"other improvements—a very expensive TRT Stealth bypass cap"

I wonder if these Strada have that cap?
post #2658 of 2938
Hey guys,
I called Gallo to ask if the Reference 3.5 was going to get the Strada 2 sensitivity boost and was told to think more along the lines of a Reference 4. Has anyone else heard this?
post #2659 of 2938
Reference 4 would be great! Would like to see them keep the price down. Dont know if they would be worth twice my Classico-4 though.
post #2660 of 2938
I just ordered a pair of Classico CL-4's. I'm a little nervous spending this much on a pair of speakers that:

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)
post #2661 of 2938
Bry_E, you can't go wrong with Gallos. I got my 5LS without auditing them (I had Ref 3.0 tho) and no regrets so far.
post #2662 of 2938
I've had the CL4's since last August and have no regrets! I am always amazed by their imaging qualities which one of the main reasons why I bought them. It's also nice they are quite sensitive so I don't need a lot of power.

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.

Feed them plenty of clean wattage and they won't disappoint.

Thanks for the reply. Got them today and they definitely sound strange right out of the box. The bass is tight and punchy (even excessive), but the mids are congested and the highs seem a little distant. I'll keep them playing, though.

What I did when I burned them in is I turned up both the Bass & Treble. This way I didn't have to turn up the volume too loud to get the drivers movin. Sounded like ()&@, but my wife didn't want the music turned up too loud! I had them playing 24/7 for about a week before doing any critical listening. Lookin forward to hear your feedback after break-in.

Have any of you guys heard the CL-4s compared to the CL-3s? I'm currently auditioning the CL-3s (and using them with two SVS PB1000s), but I feel the low end of the CL-3s might be a little lacking. I'm wondering if trading up to the CL-4s will remedy my problem as the PB1000s are great for movies and decent for music, but are not the best musical match to cover the low end of CL-3s.
post #2668 of 2938
I still use a sub with my CL-4's. I have mine pulled out away from any walls to give the best imaging, not the best for bass reinforcement.
post #2669 of 2938
I'm hoping someone has had experience with both the 3.1's and the 3.5's.

I've owned the 3.1's for about 5 years and I love the low end and midrange of this speaker but looking for an upgrade with the high end.
I'm looking to reproduce Brian Blade's cymbals splash as realistically as possible.
( and of course other great drummers)

Would the 3.5's accomplish that goal? I am leaning towards the 3.5's b/c I love the Gallo imaging plus 3.5's have now dropped in price below 3 grand and there are only 50 left.
Can anyone testify that the 3.5's have a significantly better high end?( than the 3.1's)
post #2670 of 2938
Hiya, welcome. I believe user barryecohen has both of them and I think he is the most competent to give you some answers. He also published some comparison some time ago in this thread. I can just recommend you that you can look for useful information about 3.5 from page 46 on as at around that page AG 3.5 emerged.

best, d.
