From the Anechoic measurements then you'd think they would be slightly on the brighter side, but you should be able to cure that by just flipping the HF Trim Switch on the back of the speaker to -2dB, which will bring 2kHz & above more inline with the bass.are these JBLs on the brighter side?
I own several of the generation 1JBL LSR305s and the generation 2 JBL 305P Mk IIs. The sound of the two corresponds to measurements: the Gen1 speakers sound balanced and pretty neutral, and the Gen 2s sound a little bright, owing to their slightly tipped-up top end. They can be made to sound virtually identical with external DSP correction, in my experience. (I use Gen 1s as ATMOS height speakers in my main system, and Gen 2s elsewhere around the house outside of my main ATMOS system.)are these JBLs on the brighter side?
I'm thinking of using JBL 305P mkII and LSR310S sub with both a XLR DAC and a phono preamp. My DAC has volume control, no problem. But not my phono preamp.
I am thinking about using a Nobsound XLR/RCA switcher. I also see they have one with passive volume control:
Little Bear MC2 Mini 2-Way Fully Balanced XLR/RCA Audio Converter Switcher Manual Selector Box Preamp
Warm Tips Compatible with most audio devices, but cannot guarantee 100%. If there exists common ground noise, please add an isolation module between MC2 and your device. Features Small and charming size, but the commonly used interface complete, support full-balanced audio signal and...doukaudio.com
Any other passive volume control recommendations? JBL Nano Patch+?

Maybe just the volume control on the RCA from the phono preamp (Shiit SYS?), and use the volume control on the Topping DX5 for best SINAD on digital sources.
Stepped attenuator, better than Schiit SYS with potentiometer?
Maybe I just should connect my Gustard H16 as a preamp for JBL305P/LSR310S, it has both XLR and RCA input. But then I can run the DAC XLR straight to the speakers.I'm thinking of using JBL 305P mkII and LSR310S sub with both a XLR DAC and a phono preamp. My DAC has volume control, no problem.

When I just use my DAC: Topping DX5, which has a preamp-mode so I can control the volume: no problem.
But if I want to connect my turntable to the JBL-setup, I have no way to control the volume in a easy way, other than turning the knobs on the back for the speakers one by one.

Get a little ADC for the phonopre and connect that to the appropriate digital input on the DX5. You may also be able to make use of your computer's onboard audio line-in if you have that.I'm thinking of using JBL 305P mkII and LSR310S sub with both a XLR DAC and a phono preamp.

Hi,
At long last, here is my take on the EQ.
Note:
I just implemented a routine to automatically export the EQ I design as APO/Peace config file.
I suggest you use Peace on top of EQ APO:
https://sourceforge.net/projects/peace-equalizer-apo-extension/
You just need to import the file as @sweetchaos (thanks for pointing the info) shows here :
https://www.audiosciencereview.com/...s-community-project.14929/page-14#post-536526
I have attached a the config file to import.
Note that there is an automatically generated Preamp gain that is based on the actual peak gain of the EQ rounded up for a tiny bit of headroom in the hope of avoiding digital clipping.
Spinorama no EQ:

Rather than showing the raw directivity I applied the EQ to the complete Spinorama data set:
EQed LW:
View attachment 88989 Probably better if listened 15deg off-axis on the horizontal plan:
View attachment 88987
The vertical directivity seems better than many but still better stay within +/-10deg of the tweeter axis
View attachment 88979
here is the EQed directivity which might be better way to visualize than a straight normalization as this way, one should avoid normalizing to some artefacts only present in the ON curve
View attachment 88988
Normalized:

Given the price and the EQed performance, that is really a great speaker if the hiss is not an issue...
As usual the rest of the data is attached.
If you try the config file please report if you experience any issue.
Tanks in advance.
Yes, you're wrong.Just a maybe stupid question. Considering that JBL have an internal DSP... i think that no matter dac you use..they will sound always the same as the signal sent to xlr input will be anyhow converted...am i wrong?
