My new jbl 4365

[4313B]

It adds a whole new level of fun doesn't it?

Mctwins, for the love of Pete and all things holy, would you please take the 4365's a bit out of the corners or angle them? Or something? It's killin' me!

Hallo!

Don't need to angle them in or move them out.

Absolutely great freq response without any modal ringing.

Nice to have a good room! Congrats, again.

Nice waterfall plot. Does the "shelving" above 600Hz give any sense of chestiness in the mids/low mids? Perhaps not with the room treatments you have.

Thanks, now we know that there is nothing wrong with the speakers.

Nice

Now I am not follow you. Off course I have good punch in the mids/low mids. Don't understand what you mean "Perhaps not with the room treatments you have.", please explain?

Or, do you mean from 100Hz to 600Hz or above 600Hz to 20kHz?

Hallo!

I just want to be clear here, I am not using any PrePEQ or Post PEQ or any other settings, meaning no DSP settings at all. This is the room response curve at my listening position.

Some pictures from the inside. Nice things one can do with a camera.

I manage to stick my hand in one of the ports. At least, it is 1501FE and also real high-end cables

[Mctwins]

Hallo!

I am just trying with single wire instead of bi-wiring and using the jumpers that came with the speakers. This config is here to stay. Sounds way much better, don't ask me why!!

I will use the other pair to my 4429

Hallo Mctwins,

Interesting photos, thanks for sharing!
Looking at your photos it seems like the damping material is the same as in the M2: https://www.youtube.com/watch?v=jDTLZCNzhFQ
It does not look like fiberglass, more like polyester to me (sonofil?) ...
What material do you think it is? Is it thick?
Are all the walls but the front baffle covered with it?

It looks the same as far as I can see....not so thick but I will check it to be sure. Looks like 25mm. There is no damping on the front baffle.

Seems that it is seperated boxes, one for the woofer and one for the horn.

I did some measurement from Crown amp and it have a feature called SLM(Sweep Load Monitor) and allows one to measure both the impedance of the load attached to the amplifier channel as well as the frequency response through the internal processing.

Here is the curve...with Bi-Wire config.
