No need to apologise @AlleyCat. We are all (mostly) in the dark with regards acoustics. I think especially because effective treatment is difficult to achieve, and expensive. Add to that the vast contradictions regarding efficacy of various media, and it becomes a PITA. I think this has been a...

I’ll elaborate a little for your topic Stefan. As I’ve said in my thread, I’ve been a HiFi fan for a long time. I have heard many systems in many rooms. For the longest time, I didn’t have any idea what good sound was supposed to be. I would listen to some system (private or at a shop), and try...

I suspect there is something to this👍🏻. I do not receive reflected energy in the mid to high frequencies coming from those areas. On the other hand though, my previous speakers did not fair nearly as well in the same positions.

While the 5% no hooliganism period draws to an end, let me leave you with this:

What matters is hidden here: The pink trace. Phase. I don’t pretend to understand it. In REW you can do various things, like unfold this graph. I expect that someone like @Timber_MG might shed some light on “what my system sounds like”, but even considering my regard for the guy, I doubt it...

This gives you a time per frequency response. It does not account for phase response.

This means nothing, without context of the phase response of the reflected energy from a given room.

You don’t know how often I have thought about that very thing. There are SO many opinions in HiFi, but that is what it ultimately comes down to. There are a fantastic number of variables in sound reproduction, including the rooms it is done in. Please understand my previous posts in the context...

In essence, what I’m saying is that a straight, downward sloping curve, is the safe bet. It excludes bad rooms, but gives no credit to good rooms. Depending on the phase behaviour of a room, a hump or dip in the frequency response is either constructive, or destructive. So too, by authority of...

In continuing my 5% hooligan break, I want to say some things. I’m not trying to be argumentative. I have taken care to try and understand what my measurements mean in my room. I get that my room is far from ideal. However. I think there is more to the ideal “story” than commonly understood...

I figured out why the scales were different. The actual RT60 rose to over 1.2sec at a frequency I dont recall now ( low, though). REW obviously bases the scale of further graphs off the relevant data band. This for the measurements I took at 1m from my MLP.

I’ll have to learn to check for that. I didn’t change settings to cause the difference. I don’t know why the scales are different.

Mine are the first edition. The individual sides, spine, top and bottom are bolted together. The Carmel 2 is machined from a single huge billet. The drivers in the 1 are modified Scanspeak. The woofer, from the Revelator range, and the tweeter a highly modified Illuminator ring radiator. In the...

Its an open plan living, kitchen and dining area. Theres not much possibility of changing positions. Stone floor, concrete ceiling and brick walls. Then theres that floor area I mentioned- it has a correlation to the wall and ceiling area that would need treatment. No trivial feat. And not cheap...

I’m not too surprised by the FR graph. Its well known that FR changes drastically around the room. But the RT60? That is a measurement of the room behaviour, right? It shouldn’t change.

How about the FR graph: All I did was move the microphone 1 meter.

I’m sorry to throw a spanner in the works here but….. I just took new measurements. I moved the microphone 1m straight ahead from its original location. So away from the back wall. Look at the RT60 decay now:

Just looking at the distortion graph I posted, isn’t it suspicious that noise floor, and distortion follow a very similar trend from about 100Hz? How much is the noise floor contributing to the distortion measurement? Edit: I live in a gated estate, and right next to the park. It’s seldom that...

Heres my distortion graph in percentage. Just for my reference, please post yours.

Your measurements look spectacular! Would be very interesting to hear what it sounds like. I’m only a hooligan 95% of the time.😉
