Onken Plan use hivi-research W12 speaker (Off Topic)

Hi,Bert
i want to build Onken using other speaker, not vifa wp25-08-09. the speaker technical data is:
hi-vi W12
Fs - 28 Hz, Re - 6.5 ohm, Mms - 89.7 gr., BL - 14.1, Qts - 0.42, Qes - 0.52, Qms - 2.16, Vas - 156 liter, Sd - 34 cm2, Sensitivity - 90dB/2,83V/1m, Power - 150Watt

i calculated it using Onken-calc, the result is similer to vifa wp25-08-09.
l'cent also is about 50cm, and the aligment "n" is also about 9. so, can i use this component to build a onken speaker?

BTW,i'm chinese, so pls forgive me for poor english expression.
thank you!

Hi Peter,

i calculated it using Onken-calc, the result is similer to vifa
wp25-08-09.
l'cent also is about 50cm, and the aligment "n" is also about 9. so, can i
use this component to build a onken speaker?

If the driver does fit (dimensions) inside the enclosure then you can use it. The moving mass is pretty high for a 12"(?) driver though...

BTW,i'm chinese, so pls forgive me for poor english expression.

No problem, you do English much better than I will ever be able to do Chinese!

Cheers,

Bert

Hi peterlhp

Just wondering if you are using the onken calc from http://melhuish.org/audio/software.html?

I plugged in the values and found that the L'vent for the vifa WP25-08-09 is 65.623cm (35cm is the max recommended by that excel spreadsheet, otherwise, the driver is supposed to be unsuitable for onken cabinet usage).

The driver that you are using gave 181.424cm for Sd @334cm2 and 174.737cm for Sd@340cm2 (you had a typo error, your Sd was given as 34cm2).

If there are many satisfied users of the Onken Vifa cabs from Bert, isn't it strange that the original vifa WP25-08-09 driver gave an unsuitable L'vent area from the calculator(based on research from Eijiro Koizumi, Jacques Mahul and Jean Hiraga)?
