SB26ADC compared to SB29RDC

I was under the impression that the rather exotic and expensive ceramic Visaton KE 25 SC had a built-in Fs resonance LCR notch around a low 800Hz.

Visaton seem not to have measured it above 20 kHz.

But a nice product, for sure. People have a good time with it.

I was under the impression that it uses RLC at both resonances.

Oh, and i'm not a fan of Boxsim. Everything looks nice and smooth, and it isn't. I mean, it is if you do your measurements and then apply 1/3 octave smoothing.

Looks to me like the Visaton 25 SC uses a phase plate at the 25kHz top-end.

The protective grille is fitted on the inside with an acoustic low-pass filter in the shape of a transparent ring, which does not begin to operate until 25 kHz are achieved, when it damps any material-borne resonance.

Honestly, Zvu, I have an open mind on simulators. Boxsim version 2 seems to be based more on actual off-axis measurement than 1.2. Some of my drivers are wildly different in 2.0 measurement than in 1.2.

What I like about Boxsim, is it isn't too technical. Just kinda works roughly. And is very good on practical bass loading. 😀
