Hello
I’m jean from Berlin, i have the opportunity to get a pair of Chicago and after a long listening session in tricky room (high celling , with some echo )
I have questions for those who own those speaker - as it was for me the first time to listen those rare speaker and something remains strange for me as feeling after having done this listening session (esoteric class A 2x20 watt source digital only)
I have the strange feeling that something is not correctly set on the crossover meaning that the lower part of the frequency response seems to be without any blood or energy, ultra flat, like if the woofer was not obtaining the right signal.
From mid to high range every detail is sublime. But the bass looks like totally absent.
Carmina burana, arykah badu , Michel Godard, parmigiani, Brian Eno, joy devision live, jazz live (bass percussion ) even modern low kick from techno track nothing bring the lower woofer in life.
I can’t believe this low driver is set like that so flat.
My questions are the following regarding what I tried with crossover
I change the position from 3 to 1 to avoid to cut lower bass, but nothing really change drastically (slightly more deep)
I connect the speaker cables on the right side of the électrique cable (seems that the signal enter via the low driver before going the tw and medium)
The position of the tw/mid on 3 (1,2,3,4)
The position of B1 seems correct (connected for single amp mode)
Question 1/
Did you have any comment like mine which can result from a poor signal on bass woofer resulting from a wrong cable installation?
Question 2/
Is the speaker optimized for tube amp rather than transistor class A?
Or is the speaker optimized for bi amp to provide a dedicated signal for the low frequency in order to obtain something more deep and warm (loud)
Question 3/
Should we consider a full analogue set up with the Chicago to obtain a more warm live stereo scene with the overwarmsound coming from phono signal?
Question 4/
Position and room : the Chicago seems to have a significant interaction with the position of the speaker and the mid absorber/ difusor which should be place behind the speaker or not - Has there is no closed box / bass reflex for this bass driver do you have a tips to create this loud bass sensation I’m triing to get?
Question 5/
I’m planning to use the speaker bi amp mode on luxman L595 class A , do you have any scheme to help me with to understand the full setting of crossover In order to make sure I find the best set up in bi amp mode ?
Would you recommend only tube to drive the low frequency in bi amp mode
To conclude :
I’m really impressed by the speaker , the esthetics is absolutely insane, I’m in love of the stereo scene and the detail of reproduction of the mid/high, but I’m really confuse with the no capacity to feel loud bass align with the low frequency driver. I want to purshase those speaker I love but as you can imagine I have a little stress about the final reproduction of the bass sound in my listening room
Many thx for any comment to my question
