Pearl Acoustic Sibelius

[Hondasnl]

I can try to build it by myselfs .
I have the drivers here .

 

[planet10]

The drivers in Sibeluis are not quite the same.

If you have A10,.3 you should use a box designed for it,.

I think this should be the correct cabinet drawing for the Sibelius CG.

Edit: the location from top of cabinet to center of driver exactly scaled and measured from my computer screen, exactly 120mm.
Also done with the bass opening on the bottom, exactly 2x 50mm.

Yup! Pearl Acoustics did that for you ;-).
Specially for the Markaudio Alpair-10 Gen 3 Gold.

Sibelus doe snot use Alpair 10.3.

It looks like it ;-) .

 

[planet10]

Cones on the A10.2 and A10.3 look the same. The Sibelus driver is neither.

I can say no more (i do know more).

But A10.3 is the DIYers starting point. I expect a pair of A10.3 Pensils would have very simialr performance.

Its probably tweaked version of Alpair 10M for Pearl Acoustic

Yes! Noooo...

But I still think it's pure commercial matter ;-).

DDVP 15 looks a bit closer in design to Sibelius than Pensils, is'n it?

Yes. In a sense.

Just another decal on the back specialy for Pearl Acoustics haha.

An ML-Voigt is closer, but there is a trick that turnes an ML-TL into an ML-Voigt.

The picture of the Pearl driver uses MUCH thicker wire than i would ever use.

In the sense that Harley has to buy a lot of drivers to get the drivers he uses made.

Note that Scott (and myself to a lessor extent) were involved in the original lineup.

Pearl Acoustics speaker cable is at least 16awg IIRC.

@Hondasnl That youtube video has already been posted #104 in this thread.

Thanks for the reminder.
Sorry.
I'll remove it.

The magnet looks also exactly the same haha.
Same diameter and height.
Also Re 7,2 Ohm (edit: and efficiency).

But I believe you .

 

[planet10]

Mistake #1 in the review: it is a nominal 5.25” driver (which has a cone 100mm across)

Mistake#2: Not a phase plug, but a dustcap, but it does act like a 1” tweeter.

Terminology: A voigt is in the TL (quarter-wave) class of loudspeakers

Good comments on what no XO brings.

Hegel had too low an output impedance… too much damping.

Except for the colour of the label, A10/10.2/103/10p you couldn’t tell the magnets apart/.
