AsciLab speakers are about to launch

[AsciLab]

Can we expect the horizontal dispersion of the 2-way to be marginally better than the vertical dispersion of the C8C? In other words narrower than ideal? Or have you implemented some trick solution like 2.5-way?

It is simple 2-way design.
Following the sim result, it keeps +/-30 deg at -6dB line.

@AsciLab D&D have announced their new flagship the 15c. Will your Purifi based cardioid system accept the challenge?

What challenge?

 

[Chaos01]

Hey @AsciLab , will you provide a waterfall Plot or a burst decay Graph Like Erin visualised for the C6B ? Im interested for the A6B but would be interesting for all your speakers.
Also curious for the C8T Rendering Pictures

We are sharing approximate reference images of the upcoming 2-way center speaker and 3-way center speaker currently under development.

The 2-way center speaker features an MTM configuration with two 5-inch drivers.
The 3-way center speaker adopts a WTMW configuration, incorporating two 8-inch woofers, one 5-inch midrange driver, and one tweeter.

The 2-way center speaker is planned for release first, around April–May.
The 3-way center speaker requires additional unit design work, so it is expected to be unveiled after the summer.

Are you not considering making something like the kh310? I need something useful for my desk.

 

[markstein]

Then why not buy the KH310?

It's not bad, but it seems like it's been out for way too long

C8C

C8C

I was going to say the same.

In fact, doesn’t the C8C out-monitor most monitors?

I'll wait for them to arrive before I answer you

What will you be comparing them to?

Forgot to ask - does it look like distortion is pretty high here in lower frequencies for C8C or am I misreading something?

 

[Purité Audio]

Distortion always rises towards the low bass but if you compare C8C with 8C…

I wonder what's the reason? Do cardioid speakers distort more?

 

[goat76]

I wonder what's the reason? Do cardioid speakers distort more?

Yes, they do. That is unfortunately the trade-off when forcing the bass to be more directional.

 

[Coltr@ne]

Vd=Sd x Xmax

Interesting - thanks for explanation

That range (under 100Hz) is not cardioid range. The main reason of the distortion is based on Xmax like as other speakers.

If I make the beam width more tight and control deeper range then the distortion might be higher. More deep and tight directivity needs more cancel.

In this case C8C doesn’t lose much SPL due to optimal driver placement and proper electrical delay. So only 1 or 2dB is lost around 100Hz. Therefore, the rising distortion is not related with cardioid feature.

But the passive cardioid design is different.
Usually there are a lot of odd harmonics of passive cardioid design. The main reason of odd harmonics of passive cardioid is related with hysteresis distortion through the cardioid hole. The sound pressure through the hole has much of distortion and it is added to total distortion.

You can see similar distortion effect in D&D 8C and Shivaudyo Point Zero. (Sorry for mentioning specific models, it’s for examples)

Good cardioid pattern is made by proper physical delay and electrical delay. More leaning on electrical delay, there will lose more SPL, more leaning on physical delay, there will be a lot of lobbing. All is about compromising.
