[Curvature]

What move specifically you refer to? It was quite a journey to balance room constraints, room modes, stereo image etc. Some minor movements are possible but practically what I am left with is toe in/out. I don't sit in equilateral triangle, I am quite closer to the speakers than I should be, and with further toe out I feel like the soundstage is breaking up.

Anyways, it is not fatiguing so I think there is still potential for "brain EQ"

Any sort of movement of the speaker to adjust the tonal balance is positional or physical EQ in my book. I typically had fairly small living spaces so could never play much with speaker or sub positioning. Once I understood the principles of speaker/sub EQ and benefits of constant directivity speakers I stopped making small tweaks in position.

Hey everyone, I'm new in this forum and would be happy to get some advice from you:

I'm currently looking for a new set of stereo speakers in my 4x5 meter apartment living room with several acoustic elemtents. The speakers will be located at the 5m-side, roughly 30cm distance to the wall. 2,5m of one 4m-side of the room is open and connected to the kitchen. I plan to connect the speakers to the new Wiim Amp Ultra.

- How do the C6B compare to the Wharfdale Super Lintons (or even the new Evo 5.2)?
- Would the Super Lintons be too big for my room? Because I could get a pair for the same price as the C6B at the moment.
- Which speakers would be your choice and why: C6B, Super Lintons or the Evo 5.2?

Maybe you can tell me the differences I can expect from these speakers. I would really appreciate it.

Welcome to ASR!
Between the Super Linton and the C6B I would choose the latter for its better linearity, dispersion and looks (this is personal).

Can grilles for the C6B be bought and attached after getting a pair that don't have them? Maybe from the new US distributor?

 

[Toshiba191]

I plan to connect the C6B (waiting for restock) to a Denon AVR-1700H that I already have. Do you think its amp is good enough to run the C6B and bring out its potential?

Otherwise I thought to get the new Wiim Amp Ultra, but I'm not sure wheather it will be a worthy upgrade.

What do you think?

 

[ry_]

It should be good enough! You’ll get better streaming options with the Wiim though.

Is the Eversolo Play with its 110W output @ 4 Ohm a suited amp for the C6B? Or would you recommend and amp with more power output?

Ascilab have preciously said that the Wiim Amp Ultra is enough to drive the C6B speakers. Given that the eversolo puts out about 130w (Erins measurements), the Eversolo Play would play 1.5-2db lower than the Wiim Amp Ultras max output. I am going to be grabbing the Eversolo Play with the C6B

@AsciLab is there any new update on the ETA for C6B as the page stated mid-August, then late-August, with it now being currently September?

I have tried the Eversolo ‘PLay’ with the C6B ( no photograph) and the F6B, F6B/S they work fine, this is however listening relatively close 3 metres maximum.

UPDATE: as always, rationalization had to follow the first impressions

1) For some reason I expected C6Bs to be less sensitive than DBR62s so I increased the volume by few notches. But it's the other way around (85.6db vs 84.3db mean SPL measured by Erin), and while still at low volume, I was listening at a bit higher volume than usual. It was quite enjoyable thanks to the clean midrange, but the cymbals were getting too prominent for my liking.

2) I kept the EQ settings I developed for DBR62, mostly for room modes, but over time it got quite complex and reduced the bass overall (speakers are only 25cm from the front wall). While C6B's bass goes a bit deeper, midbass is very flat, DBR62 on the other hand has a midbass bump (70-200hz) up to 2db from mean. So I made the C6B leaner by using that EQ, which made the upper frequencies stand out more.

3) The C6B tweeter's constant/widening directivity proved to be a double-edged sword. Dbr62's top end is a bit brighter on axis, but its directivity is narrowing and I could effectively tame it by toeing out. That does not work with C6B at all

My brain has not yet fully "broken-in", the impression of sparkly cymbals is still present, but it varies a lot between recordings. I need to be more careful with conditioning, start with lower than usual volume and gradually increase to (my) normal levels. I may add some slope to the EQ for treble heavy recordings.

PS: I use Nuprime IDA-8 amp, which is 10 years old class A+D design. I was curious whether its (presumed) load dependency was adding a bit of sparkle. I tried Wiim Vibelink which was measured by Erin and Amir as load independent. Even with my confirmation bias fully turned on, there was no lasting relief, there were a few promising stretches, but I concluded it makes no difference.

UPDATE #2:
so I think my brain has broken in finally, I stopped noticing the cymbals

On the other point picked up on by Ascilab, I had this nagging idea of my amp not being suitable for low impedance speakers. So I decided to try 3e audio A5 amp (paired with Topping D50 III). And, again with the confirmation bias fully turned on, this time I find bass/midbass to be clearer, getting closer to the midrange clarity.

I found a measurement of Nuprime IDA-8 damping factor = 72 (at 4ohms), which they considered excellent. 3e A5 should greatly exceed 100. Is this an audible jump for an average (low volume) listener?

What are the main differences between the F6B and the C6B in regards to sound reproduction? What more can I expect from the C6B?

+1. Is there any reason to get the C6B over the F6B if I plan to pair it with a subwoofer?

C6B has lower distortion over midrange. If you integrate a subwoofer below 80Hz, you will get lower MD with C6B. Try to compare our official datas.

be aware that Wiim Amp Ultra has two class D chips, which makes it more suitable for low impedance speakers (C6B drops below 3 ohms in midbass region).

I would be cautious of considering the c6b over the linton based solely on measurements. My primary complaint against the c6b is the limited dynamic range available. Not so much that the absolute output is limited, or the low sensitivity, it is the small woofer incapable of moving both the air in the room and any emotional response while listening.

Would using subwoofer(s) be an emotional experience? If it's an option, would that alleviate that "complaint"?

That is the question. If extending the LF response of any speaker made that way can somehow make it able to reproduce music with the dynamics necessary to trick me into thinking it is real then good for it.
All I am saying is take any dead flat perfect directivity 2 way bookshelf (if you want, with a sub) vs. an altec corner horn, if such a thing exists (with the worst FR imaginable) why is it so easy to know who wins that competition no matter what is measured. It's a tough choice.

Yeah, ultimately we'd really want to hear various options in our own familiar spaces. I imagine for most of us, it simply isn't really an option

I don't really understand what you mean about altec corner horn... But does seem like the dead flat perfect bookshelf +sub(s) is likely to be my preference, based on the in-room frequency response i seem to favour.

I've had 3 different pairs of speakers in this room, with same subs and room eq to pretty similar listening position freq response - the 3 pairs not hugely different in their format (2-way , waveguide, 6", probably all pretty decent speakers), and result in room probably more similar than different, ... But i remain interested in AsciLab, and will likely get them and then be satisfied with them (maybe that's largely a state of mind).... If/when they ever become available to purchase again!

 

[jEDGEc0m]

I have to say i don't really care what is "real". Just needs to sound "good" to me.

Much of the music/recordings i like don't really have all that much dynamics left in it anyway. And sometimes that's ok -many still sound really in music enjoyment. Either way, i have to tolerate it due to little alternative.

 

[Purité Audio]

Altec corner horn or the C6B, I can easily see that as an either/or comparison!
Ahhh ‘emotional response’ the very cornerstone of subjective snake oil marketing.
