Ascilab C8C Active Speaker Review

[staticV3]

Was this announced? Missed that.

It's listed in Ascilab's roadmap PDF, just with the outdated S6C nomer from when the C8C was still called C6C.

 

[Scrutable]

Yes I missed that announcement too. Any further info would be welcome.

$28K is a pretty high end price. I suspect it will be challenging to maintain focus from $0.725K/pair all the way to $28K/pair/.

As @staticV3 states they are in the original road map, but the C8C on their own are superb, with the BX8C underneath they are going to be well, even better!

Perhaps someone can answer this question for me. What is causing the far-off axis loud spots around 500hz-1khz?

Most of that is behind the speaker, Ascilab addresses it here.

We’re trying to get less lobbing error in the same form factor by setting new preset.

Is that why Amir measures a rise around 700-800 Hz in the response of the left woofer?

I thought measuring near field would eliminate that rise.

The response is in purpose.

 

[kharan]

The response is in purpose.

Sorry, I don't understand what you mean when you say "in purpose", this got lost in translation.

 

[Grimoire]

Sorry, I don't understand what you mean when you say "in purpose", this got lost in translation.

On purpose, I think.

Is it really an issue though? I have not seen it show up in any of my in room measurements.

 

[AudioJester]

On purpose, I think.

Arw you still getting your C8C?

 

[Grimoire]

Arw you still getting your C8C?

No. Keith made sure of that.

 

[AudioJester]

No. Keith made sure of that.

Ah, bummer

 

[Grimoire]

Ah, bummer

Indeed!

 

[kharan]

On purpose, I think.

I'm not sure whether that makes more sense, my question is whether the rise is related to the lobbing error.

I don't doubt that the side woofer and its response is fulfilling the purpose Ascilab wants it to fulfil.

 

[dfuller]

No. Keith made sure of that.

That's... Not encouraging.

 

[Rick63]

No. Keith made sure of that.

Yeah, that stinks. But I've already made my opinion very clear about that.

 

[Rick63]

No. Keith made sure of that.

Perhaps @AsciLab could step in and help you out somehow?

 

[AsciLab]

Is it really an issue though? I have not seen it show up in any of my in room measurements.

Though it was already attenuated -6 to 9dB, we found the way to reduce the lobbing more without any side effects. Only a little bit wider beam width as you see though the difference is less than 5 deg.

I'm not sure whether that makes more sense, my question is whether the rise is related to the lobbing error.

I don't doubt that the side woofer and its response is fulfilling the purpose Ascilab wants it to fulfil.

Yes it is “on purpose”. Sorry for the typo.
The side woofer doesn’t produce clean curve which makes “not” clean directivity.
