in the meantime i thank you for your intervention and anything that is suggested/reasoned by you is always and in any case an improvement.
then, to be less vague... i will explain better why active speakers are not in my strings. being someone who likes to play the #stratocaster guitar, i often go to a well-known and very large warehouse where there is every musical instrument on planet earth. in the audio department there are well-configured stations with different types of active speakers available. there is everything and a couple to which you can say, wow if they sound good, there is not. from here, also to set up a home made station, i invented a hybrid LS /3/5a, that is using one of my many boxes that i built myself, inserting recovery drivers. (see my Use a different... topic) Starting from this and leaving my two reference amplifiers (Jeff Rowland & Carver M 1.5t) in the hi-fi system, I thought I would get a sound of a certain level also on the PC station, which I will also use as a measurement station, to measure my DIY initiatives that I cannot avoid. I've always had them, I'll never recover. 🙂
I think that in the chain the weak points are cascading, that is: if the source is terrible, the rest will cascade down to the speakers and the room. If the source is excellent, then it's the amplifier's turn and that's where my problem falls! In my opinion the active speaker amplifier is poor and will never be able to make a pair of monitors sound their best like a real amplifier can.
I agree with markbakk in this case and the reason I can't agree with what you've proposed is because the distortions produced by each stage are very different and they don't compound.
I'll give an example, one distortion is to hear sound reflected from different angles.

there is no doubt about this, I also agree with you on some things, but I believe that a quality amplifier has all the credentials to drive better than a class D and that in addition to the tonal qualities and better control of the medium-low range, it puts the speakers at ease in reproducing music.
ciao Allen,
I have seen various examples of bass boost and some of them a bit bizarre. to do a quick test and to understand, what value and in what position this little resistor should go.
It just goes in series with the woofer. Normally, a crossover might give half an ohm, maybe 1.5 ohms. I presume this must be all it takes to make the difference.
I started this simulation and the default resistor was 10 ohms. This is far more than I would normally use, but it made for a good demonstration. You could simulate a smaller resistance for yourself
Here the bass rolls off at 70Hz but with the resistor it's flat almost down to 30Hz. Whatever amount you use, you want to reduce the gain on your tweeter amp for example.

if I understand correctly, this is why many crossovers adopt these resistors at the beginning of the dipole and on the woofer.
what I deduce is correct?

Not necessarily. Positioned that way they are taking energy out of the resonant circuit, likely to reduce output at the 'knee' of the rolloff.
and it is also the last situation of the chain, after the room there is nothing else.
in general and to everyone:
I have listened to some models of amplified speakers, I could also veer in my reasoning, but... damn! I have listened to models that go beyond the expense, and I don't have to, as already said previously, I don't remember where... I don't have to set up a recording room/studio, but combine my newly finished jewels with something just to make them sound good. the idea of LINN and Quad has failed, because the Quad that I like, they don't give it to me for free, in fact they want a lot of money.
@AllenB
I did a test with 10ohm and I would say that the bass has changed, but not much, while the attenuation was very noticeable.
If you still feel the same after offsetting the attenuation then as you say, it could be other things about the amp. It's fairly common to hear comments about direct amp connection sounding cleaner, which can be a way of describing what is heard when the bass is running at a lower Q factor.
wait, i just added the 10 resistor on the positive and used the crossover, the finished one...and of course everything went down.
maybe i could try to separate the positive of the woofer from the positive of the tweeter, since it's b-wiring.

since I have decided on a Desktop/studio configuration with passive speakers and in case an equalizer passage is necessary to balance/correct the frequency response, with a class AB power amplifier.
the amp could also be a Class A, if there is a good compromise on the price, but eventually I would opt for a professional 100W class AB amp built in dual mono with two important and separate transformers. also because the first test I did with the class D lent for the test the performance is really embarrassing.
(let's see what I find, so I leave the Carver and the Jeff Rowland on my reference hi-fi system) I have to convert the RCA cables (I have many) to Jack 1/4 to go to the output of the Scarlett 2i2 3rd.
do I make a modification and connect a nice Jack directly, or do I get an RCA to Jack reduction from those on the market?
