Upgrading sub to get a live feel.


I currently have a set of JBL 4319 which has its history as 4310. They are studio monitors and as a result they sound like studio monitors you hear everything, but they lack the physical presence on the low end. They have wonderful mid range and voice presence. I also have a pair of SVS SB1000 to help with the low end. 

I want to eventually upgrade to JBL 4367 with upgraded pair of subs, for this reason, but in the mean time would a sub upgrade be considered before the speakers.

Dear @thewatcher101 : what @mijostyn posted about the 4367 crossover frequency is truly relevant and a main parameter to take in count.

It crossover 700hz and that means the the IMD level distorions are really high in the mid range and up to it due to the developed harmonics.

The main target to add true subwoofers to any passive speakers is that the IMD generated for the speakers woofers goes really down and when this happens your room/system quality whole performance goes to the " sky ": nothing less, you will discovery a new quality level performance even if you think you know very well the resolution of your room/system.

A " side line " adding true subwoofers is that we can get true low bass frequency range to honor the MUSIC.
Rigth now you don’t have neither of those trgets.

In any room/system MUSIC belongs to both frequency extremes. As better the overall bass range and HF range as better not only mid range but way better whole system resolution and system listening quality


You can read something about here and why:

https://forum.audiogon.com/discussions/do-you-think-you-need-a-subwoofer/post?postid=310058#310058

Now, if you normally use your system to listening MUSIC then normally you listen MUSIC at one seat position because at mid range/HF ranges we can have perfect response in those frequency ranges at one the seat position.

For that you only need two true subwoofers ( the ones that goes down to 16 h. ).

The Harman Group ( JBL, ML, Revel, etc, etc. ) proved that through scientific research. Here the link:

https://pdfs.semanticscholar.org/00da/51387c572cfd27c0256cb15e44e976a1a72e.pdf

from those white papers:

" " Four subwoofer at the wall midpoints (configuration 11) was the best practical configuration in terms of MSV. Two subwoofers at opposing wall midpoints (configuration 6) was nearly as good and also offered stronger low-frequency support. These results appear to be generalizable to reasonably dimensioned rectangular spaces [19] . ""

The manufacturer of DBA solution ( Audiokinesis. ) posted in other subwoofer thread:

""" You can get good bass in one sweet spot with two equalized subs. ""

No one needs more than two true subwoofers for one seat position. The key words are: true subwoofers. Not the ones you own or the ones noble100 owns.

Wait for your 4376, do it a favor and don’t waste your time or money before those 4376. Patience is always worth to do it for its rewardings to collect.

Regards and enjoy the MUSIC NOT DISTORTIONS;

Dear @thewatcher101 : You can't have deepest  bass no matters how many of those SVs you use becuse are not true subwoofers and with all respect just forgeret of what those gentlemans said about 3-4 of those units, just can't do it.

If you want real bass then you need true self powered subs that can goes below 20hz and you don't need more than two to enjoy it at your listening seat position.

In the other side if the 4367 already comes with the low end range you need then and as the other gentleman gave the advise to be `patience I agree with him: be patience till you have the 4367.

Regards and enjoy the MUSIC NOT DISTORTIONS,
