You don't really have to have anything to sit on. Just some good gear.Settee here.
Measuring in a room is difficult, so your measurements shows a lot of room modes and reflections. I'm no expert, so can't advice much, but eliminating the room by going outside is a good method, if you can. In general, consistency in levels, angles and distances is important. Moving the mic a few centimeters matters. Looking at your room, there's huge amount of reflective surfaces which could be lessened. Curtains, carpets, cushions, mattresses, blankets...Yuck! My measurement is pretty ugly compared to the NRC plot. Seems that I have a lot of room for improvement. I could try:
- Measure at higher SPL
- Measure outdoors
- Instead of the Creative SoundBlaster X-Fi Surround 5.1 Pro, I could use a Topping DX3 Pro+ that I normally use in the Living Room system.
- Check the amplifier - Seems like I may have a boost from 4Khz - 15Khz
- Better microphone mount? I'm not sure what I should do differently.

With respect to microphone, you could just wrap some soft stuff around the mic holder. Not sure about your rise in the highs, but doing in-room is always compromise. One could show a merged diagram with two different gatings; below my speaker in-room with 5 and 20 ms window. This is also closer distance mic-speaker, around 60 cm but the woofer is just 5.5 inch/14 cm.Yuck! My measurement is pretty ugly compared to the NRC plot.

Hmm. Looks like the Dynaudio won -- based on the photographic evidence. If kitty wanted the Yamaha, methinks they would've pushed the little loudspeaker off the edge -- as cats do.

PS Gorgeous puss.
It should be mentioned that Steve Jobs, as he got older, bought a sofa.
I had some time this afternoon to run a few measurements of the 4311, on axis different parts of the speaker. Here's a comparison chart, showing just from 1K up. Quite a lot of variance for moving just a few inches. I haven't ugraded my measurement techniques yet. This was just level matched to the prior measurements and checked for consistency.In such configurations we measure just below the lower surround of the woofer and above the mid-tweeter if I remember well.
But that may vary too by centimeters,one has to test.
Sure! I'd love to see measurements of other vintage speakers.Hello,
I've also meassured several interesting vintage speakers. Is it ok for me to post them here to make some sort of collective thread for vintage speaker meassueremenents?
Best Regards Markus

I have some measurements of my vintage speaker coming up. I thought of creating a separate thread with a similar title, e.g. "Measuring a vintage speaker: xxxx yyy zz" (where xyz refers to the brand name and model). We could then link to the thread in here. Your call, @bconline. It's your thread and I didn't want to hijack it.Sure! I'd love to see measurements of other vintage speakers.
How was it now? For the midrange driver, there is no crossover, not even a coil, that cuts off the higher frequencies?I had some time this afternoon to run a few measurements of the 4311, on axis different parts of the speaker.

From what I know the original 4311 crossover has one attenuator and one capacitor for the midrange driver and also another such pair for the tweeter.How was it now? For the midrange driver, there is no crossover, not even a coil, that cuts off the higher frequencies?
