I would like your opinion on the position of the sub.
Is it believed that there is ok ??? I want to calibrate with glm with as few corrections as possible.
8330 and 7350

Doesn't look so good. I would expect the sub to sound disconnected from the tops.
If you put the crossover lower than default 85Hz, things should improove.
Show us the GLM plot of your room and we can tell you what frequencies to try.

Other than that: PC close by is a big no-no.
Buy long display cables and some USB extenders and put the computer in another room.

Λουκέστερ:

Δεν φαίνεται τόσο καλό. Θα περίμενα ο ήχος του sub να αποσυνδέεται από τις κορυφές.
Εάν τοποθετήσετε το crossover χαμηλότερο από τα προεπιλεγμένα 85Hz, τα πράγματα πρέπει να βελτιωθούν.
Δείξτε μας την πλοκή GLM του δωματίου σας και μπορούμε να σας πούμε ποιες συχνότητες να δοκιμάσετε.

Εκτός από αυτό: Ο υπολογιστής κοντά είναι ένα μεγάλο όχι-όχι.
Αγοράστε καλώδια μεγάλης οθόνης και μερικά επεκτατικά USB και τοποθετήστε τον υπολογιστή σε άλλο δωμάτιο.

 

Where would you suggest I put the sub ??? In what position ???

I don't have a good answer for you.
under a large desk is usually no good, your ears are completely shielded from the sub.
if we put the crossover to a very low frequency, the sound waves become so large that this won't matter.
other than that, where the lamp or the PC is would work, or a shelf above the screen
More practical: put the sub in the corner behind you and measure (phase-align) with GLM,
but then the sound will only be good in the exact spot where you measured/where your head is. But that might be okay for your setup.

You'll need to try some of this yourself, do you havethe GLM network adapter?
In GLM you can turn the sub on/off. Put the sub on the desk in front of PC screen and listen to music with enough bass.
Now your tops and sub are well connected.
Next put it under the desk and listen to the same music, check if the bass sound becomes disconnected.

On the other hand, exactly this kind of near-impossible equipment positioning challenge is one very good reason to get this kit. Forget totally flat response, but decent sound is no problem.

I have my 7350 under the desk too (only option), just much more centered (but not in the middle of the room on that axis, to avoid equal cancellations). Works well enough with the 8330's crossover frequencies set to 55 and the 7350 to 70 Hz.

The default 85 Hz as a global crossover frequency is utter nonsense anyhow, anywhere - even worse with a desktop setup; Go lower, much lower, and experiment. Start with a global frequency and when you've found the sweet spot, try raising just the sub crossover frequency a bit - might work, might not, worth trying.

The graph for the sub has a dip at ~62Hz.
Try that as the crossover frequency.
