    FR worsens with EQ

    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.

    FR worsens with EQ

    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...

    FR worsens with EQ

    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 - ???

    FR worsens with EQ

    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.

    FR worsens with EQ

    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 =...

    FR worsens with EQ

    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:

    FR worsens with EQ

    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.

    FR worsens with EQ

    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?

    FR worsens with EQ

    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...

    FR worsens with EQ

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

    FR worsens with EQ

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

    FR worsens with EQ

    I'm using REW 5.20.13 to measure the in-room frequeny responses of a woofer, at 9 different listening positions in the room. To get a base for REW's EQ to work off, I then first SPL-aligned the 9 curves (as recommended in the manual) and then db averaged it with REW's controls. Next I used the...

    Massive Back to the Future-like Ascendo SMS G50 EA Sub… Cedia 2022

    Except for the missing imprints on cone and dust cap, the driver looks exactly like the A&D AD502. A&D makes an even bigger monster, the AD804.

    Pioneer Elite VSX-LX305 9.1 Channel AV Receiver with 8K video - Full Review!

    Thanks for the review, which was fun to read. And thanks also for the link to its manual. You wondered what output power the unit supplies with 9 channels driven simultaneously. For this, I suggest to look at the unit's max mains power consumption, which is specified as 750 watts. From this...
