I'm not a speaker designer/builder, but here's what I know:
- Messing with the cross-over is pointless; as you've pointed out, it deals with the transition between the woofer and the tweeter, therefore at some high frequencies, e.g. 5KHz.
- You need to work on the Qtc, the overall Q factor of the speaker/box combination, ideally 0.5-0.7 for a critically damped system. But since your speakers have a very high Qts and the volume of the box is fixed, the only course of action you have is to add LOTS of damping material inside the box. Expect a few dB's of difference at the most.
- See also this discussion; it's about ported enclosures, but sealed boxes work the same way, with a softer roll-off below the resonance.
- As an example illustrating the other extreme, at home I use a pair of subwoofers with 12" speakers, the Qts is 0.14 and the box is about 100 lt; it's a much over-damped system, I know, but I like it that way.
- That being said, the younger folks often think otherwise: my kids hate my subwoofers, they want lots of bass!🙂

I agree with your recommendations, they are exactly what I intend to do with my other big project. Large in size and sealed, I hope to achieve good bass, although I know that they are not exactly the bass ones that our " children " like, the same thing happens to you. Young people prefer basses with blows, not definition and realism, they want to feel at the corporal level, and that we pay for the broken windows, of course.....😀
Well, I do not imagine them sitting for an hour without interruption listening to music, when I released my HF speakers after two years of patient work, I told my oldest son to choose something to listen to ... and he gave me a CD of Ramones, and in a live recording, to top it off.
I remember the face of disgust that he put ... I think he had me compassion ... Finally, after long audiophile explanations and some "normal" music, I think he understood the value of my work ... but I'm not very insurance....
The stages of life...😉
PD: Very good links! Thank you !

Compared to techno/electro/hardcore, The Ramones are actually not too bad. I attended their concert once, I was impressed by their physical workout in the dressing room before the show, and, during the concert, between songs, they were very kind to announce the next number: otherwise my untrained ears would think it's the same 🙂

In fact all the themes are similar " musically" , 🙄
but you can not evaluate an HF system with electronic music and also the live recording was very poor. The sound level of the crowd's screaming was almost the same SPL as Marky's.
Of course it is easier to achieve a good recording in an intimate, small environment, as in jazz trios, etc., but there are very good sound engineers, mediocre and very bad, (as in all professions)
There are good recordings of outdoor shows - with thousands of people - well done, but this was not the case.
Sorry for OT

I was reading this article and decided to improve the chamfering.
chamfering driver holes
If we're going to do it, let's do it right, do not you think ? 🙄😀

It is almost ready, just need to adapt the frame.
The sound: Clear voices, controlled bass, zero boomy.
They deliver their best performance if they are powered with good power, there is no car cabin gain here.
PS: to prevent overheating I used the paint suitable for high temperatures. I believe that 360 degrees Celsius of protection will be enough
