Nikname is not in english, anyway Im very sorry, didn't tought i will ever post...will change.

That f12s is certainly a very desirable ans affordable OB woofer.

I see it is a product that will stop production.

Like most of the car hifi "free air" woofers they still have this unecessary heavy diaphragm needed for mini boxes, just weaker motors. The only exceptions I know are the Monacor SP-382C SP-302 SP-252C and the Ciare CS 382 S CS 322 S CS 252 S. The 15" Monacor is no longer listed on the website, but still sold, same as the 15" Ciare. The smaller Ciares are marked as out of production.

One might ask the question:
How large is this OB trend, are these people not many, but only loud in forums, when the industry doesn't react on them, or rather in the opposite direction?

How heavy ae dipole12 cone is?
How are these measuriments taken, infinite baffle? looks good, most sensitive from 50-100hz!

The moving mass of 170 g is about 17 times that of the PHY-HP of the same size (which was primarily developed for OB, or rather IB)

Hi,

FANE SOVEREIGN 15-250

Qts = 0.73

Seems they change the colour to black for this season

I liked the vintage blue better

Sells under 60€

It's not about fast and slow, look at the sensitivities of the HiVi and the PHY.
In theory it's 3dB down per doubled mass when Qes an Fs stay the same.
