Can we use your pics in SNS?

Why not! But what is exactly SNS?

 

[MarkS]

Per "google AI overview": "SNS primarily stands for Social Networking Service or Social Networking Site, which are online platforms like Facebook, Instagram, and X (formerly Twitter)"

Here some real world pictures of that setup if that might help anyone chose this color (or not!)

Looks great! The orange wave guide goes well with the light-colored wood of the cabinet.

What speaker stands are those? I've never seen anything like them.

I figured out the speaker stands: Q Acoustics Concept 20

@spoutnik12

Yeah, I thought they looked very cool. Took a bit of zooming in to see the glass rear feet to understand how they weren't falling over.

 

[spoutnik12]

@MarkS correct, they are indeed Q acoustics concept 20 I bought quite some time ago. Not sure if the proportions are still OK with the F6B since they are singnificantly bigger than my previous pair.

But as pointed out by @jEDGEc0m the glass support gives kind of an "airy" feel.

One thing that I also knew from this forum and that I experienced is that the speakers have a layer of rubber/silicone on the bottom. This makes "anchoring" them to the stands quite difficult (there is also no holes for screws). Previously I just used some pattafix (blutac in the US if I am not wrong) on the hard bottom of the cabinet that made a good job preventing accidental tipping. Now I just instructed my daughter to be careful (I guess not as efficient as the Pattafix!!).

I'm using some wood-topped bar stools for stands, and I find that the rubber bottom on my C6Bs sticks to them pretty well.

in my room that has very little concern for aesthetics, I'm just using those basic studio monitor adjustable height stands, but with the bits cut so they can go low enough if required. They have strips of similar material as what's on the bottom of the AsciLab on the platform. Grippy. not gonna slide with sound.

In time I may experiment with different heights.

So far the cat has been respectful.
Cat's not out of the bag. Orange waveguide might have almost matched the feline.

@AsciLab, the woofer is mounted into F6B enclosure with a 90 degree border around it but C6B has a sort of rounded ring around it's woofer.
Is there any issues (sound reflection) if F6B used with or without it's grill?

There will be a little diffraction in tweeter range, but you won’t notice it. I recommend to use the grille with F6B because the woofer isn’t coated so it can be easy to be damaged from sharp things or liquid.

 

[Bwaslo]

Isn't the ceramic coated C6B woofer equally if not more susceptible to damage from sharp things or from poking juvenile fingers? C6B doesn't come with a grill.

Aluminum is more durable than paper.
You can order additional grille.

Some further impressions (yeah I told I had no objective way of measuring "sound"...).

I ran the Wiim "roomfit" correction using my Ipad and what a difference it made. The main difference I can "feel" is in the lows ! It goes so low in the "very lows". Seems it's not even a sound but some vibration you can feel in your chest. I never felt that with my previous speakers. According to my correction graph it removes some of that bass but actually adds some in the very low 44-49hz which I guess is what I can "feel".

Here the graph in case you want to see how bad my living room Sounds!

I applied the spinorama EQ before the room correction test:

You seem to be boosting frequencies that are below what these speakers are designed to comfortably output, e.g. at 37Hz and 56Hz (if it is the latter EQ list you are using), and 37Hz is in subwoofer territory (unless of course you do have a sub and are high passing the mains).

I'm sure someone will correct me if I'm talking rubbish, but I'd not think boosting so low would be recommended.

 

[MarkS]

The two EQs are working against each other: one is applying a boost at 57Hz, the other a cut at 56Hz.

I would just let the Wiim room EQ do it all.

 

[spoutnik12]

Yep I asked myself the question to why I would have an EQ with Roomfit... Seems to indeed useless to have both. I will redo it (should still give pretty much the same output to my understanding).

Now I saw @WeekendWarrior comment about safety of bumping such low frequencies. I am not using a sub and do not plan to add one in the near future. Is is really that dangerous (maybe @AsciLab can chime in)? I am using very reasonable sound levels.

If so what kind of lower limit should I set in Wiim's roomfit config as lowest frequency (and highest ?) to correct? Thanks !

Hi quick question about the C6B, my banana plugs are 20mm long and the binding post only take 10mm, they stick out too much and are not that secure. So I unscrewed the caps and put the plugs in the holes. I noticed one of the post turns with the cap as you screw it down, no biggie I just held the plug to prevent it from turning. It works quite good but I really like the idea of being able to plug and unplug with bananas. I am think of replacing the posts with longer ones, what is the diameter of posts when they enter the cup please? I don't want to dismantle just to measure. Will M6 work?

edit: they are M4 and should be very easy to swap out without soldering if you get M4 replacements. Lets hope I can find a longer ones in that size.

 

[Raiju]

I am a bit disappointed tbh, the signal travels from speaker cable to brass to iron nut to iron washer through 2 cm iron strip. I am not going to chew out here why that is bad, Oh well, it will be upgrade for me since I planned to replace binding post anyway, I just have to solder a bit.
