Yes, in your design, it´s possible. One could:

1 highpass up to 2. order
1 lowpass up to 2. order

or 1 highpass up to 4.order

or 1 lowpass up to 4. order

Notch, HF uprising is not possible, in Jean-Michel´s scheme, it is (but there the lowpass is missing). Combinig both would give more possibility (2 x 4.order filtering plus 2 x Imp EQ, Notch and HF-EQ, allpass alltogether are still not possible, but you have do draw the line somewhere...).

One suggestion: if each series LRC-branch in David's template could optionally be changed to a parallel RLC circuit, we could get quite a bit more flexibility.

Hi Bjørn,

Thanks for the suggestion. It would complicate things a bit, but it might just be manageable.

Kind regards,

David

Hi Sabbelbacke,

I agree that the line has to be drawn somewhere .

Perhaps the inclusion of Bjørn's suggestion would be a sensible compromise.

Kind regards,

Hello,

Eventually R and L can be a single element as (e.g.) in the excellent piece of software Power Suply Designer (2)
PSUD2

To fit to Bjørn suggestion each RLC circuit could be chosen parallel or series ...

In this Case, if every "slot" is changeable between R/C/L, then this would cover most cases:

Of course, if you go this far, you are not far away from the total flexible matrix-soultion, where you are free to do anything

Still watching.

And the show is quite interesting.

As for flood gates of non stop questioning opening, it doesn't look to bad in the request department.
And the solutions offered up look very positive. And very flexible.

Where to download hornresp ?

I go to hornresp.net.ms

and I'm directed to Start | *JOYNIC.COM - Free Domain, Webspace, E-Mail

 

[Sabbelbacke]

Strange, works fine here, but from another ISP, I get strange results, too.

Try

Hornresp

 

[GM]

It starts to load for me, but then redirects to joynic.............

Thanks for the mirror site!

Well now that the .ms domain has "expired" David might get the .net or .org through a registrar like namecheap and only pay ~$10 (coupon = TLDSALE) a year since he has hosting already. Or maybe the guy squatting the .com will point that in the right direction, or hand it over since there is nothing going on there.

 

[Sabbelbacke]

The hardware-test site is the one where its actually hosted, I`ll fix that as soon as the kids are in kindergarden

 

[Sabbelbacke]

ok... done. Simply switch to www.hornresp.net (without .ms at the end).

Thanks man

Hi Sabbelbacke,

Many thanks for arranging the new hornresp.net address.

I have altered my forum signature and will change the Hornresp automatic update advice message at the next release.

Kind regards,

David

@Dan
you´re welcome
@David
I think that´s all there is to do for now in this matter. google will update its index in a few days, so everything will be back to normal an with a real domain it will be more reliable from now on.

Hi Sabbelbacke,

Excellent - many thanks once again!

Kind regards,

Not necessarily. The calculations can be almost the same, the active part can simply be fed to a constant impedance instead of the changing one on a real speaker.

How about implenenting a plugin interface at Rg and Re, so every filter one desires can be flunged in there, let´s build some VST Interface, this way David doesn´t have to do the filterstuff himself an we can even implement FIR Filtering (hihi, just playing with my mind, just kidding).

that would suffice.
i tryed bjorno's method but i can get it to work.
the way i do it now is to get aprrox the same excursion curve in winisd(around near fb),and simulate a hpf (and eq) to see if excursion is below the first peak after the first dip.
edit /to make it clear.

Hi epa,

Sounds like AkAbak would be easier than that.

i'm not sur but doesn't akabak do a passive filter?
if not that would indeed be easyer,tnx.
also how do you get a parametric eq in akabak?

Hi, AkAbak do passive or active filters. Here is a suggestion of a PEQ that should be entered into AkAbak like for an HPF or LPF active filter using Laplace transform:
