If this ever becomes an international standard I will be particularly interested to see what lengths cables will be available. Current high speed cable like USB C / Thunderbolt or (true, 48GBPS) HDMI 2.1 cables longer than 6' / 2m are really hard to find, or very expensive. I am already looking...

No subscriptions, saves money :T I stream only what is availabe for free, using computer, smartphone, a webradio (from Technisat) and HEOS on the Denon AVR X4500H, from sources like Youtube, Soundcloud and webradio stations, via TuneIn.

Same here (although for me it's "only" 45 years :) ). I remember buying some used LPs back in the 80s of which one was very dusty and sounded miserable. I then washed it in warm water with dishwashing detergent then wiped it dry with I don't remember what. This improved it a lot, but not quite...

I did that now and got much better results. It is not perfect, but that was expected. I will now continue with the 2nd woofer in the second (left) position.

We are talking about our living room here. We are not always listening from the same position - quite on the contrary. I identified 9 more or less typical listening positions that I then defined as spots to take my measurements. If you know Denon AVRs, they also take measurements from 9...

Thinking about this I wonder where is the real difference between house and room curve. Both basically "bend" the (theoretical) HiFi ideal of a perfectly flat FR, just for different reasons - ???

With a (truely:redgrin:) flat target the EQ gives me many filters, more than my DSP accepts per (output) channel. I had to reduce the target flatness to 3dB to get the number down to 8 which I can enter into the DSP. I will make a new series of measurements and compare again.

Thanks a lot, that was the piece of information I had forgotten. Now that I see it (again) I remember that I experimented with house curves long ago, but then concluded that I better target a flat response... and forgot about the house curves:gulp: Until your "reminder" I thought house curve =...

When I click help > Check for updates now I get "REW is up to date".

My target response is a plain flat line. And I'm not adding a house curve, as can be seen in this (excerpt from above) screenshot:

I don't have Klippel test equipment, therefore I can't make comparable measurements. My setup is a Windows laptop running REW, a Focusrite Scarlet 8i6 USB soundcard, an ISEMcon EMX-7150 test microphone and a Technics SE-9021 main amp.

No, this is a 6 inch Woofer - Reckhorn D165i - in a DIY closed box with 27 liters / ~ 1cft. What gave you the idea that this could be a JBL 305P?

Thank you, John! The filters produced by REW often puzzled me in other cases, but until yesterday they always turned out to produce a significant improvement of the FR. I wasn't aware of the possibilty to define my own driver target until now but defined one now. And I manually set the target...

I transferred this into my DSP as follows: Did I make a mistake, or misinterprete anything?

I don't think so, I let the EQ "find" the target level. Anyway, here is the mdat file.
