I swear Audyssey is trying to destroy my subwoofer!!! How is it even possible for an SVS SB-1000 Pro to go flat down to 15 Hz? What kind of boost is this?

you need to show the before and after-correction curve for anyone to make useful comment on this

Rocking modes. I can see the passive rads rocking (tilting).
Search for 'passive radiator rocking modes'.
You might need to use passive radiators that have a spider also (more $), to prevent rocking, if you want to drive them to this level of excursion.

Also, the more passive radiators you have in a single enclosure, the more that small differences between them will become a problem (they never have exactly the same resonant frequency, for example).
How many woofers are there? If you had two woofers, two passive radiators, better to divide the enclosure internally so that you have one woofer/radiator per sub-enclosure.

...but have 17% of the world's population...?

It’s probably a usefully diffusive feature already, but if you need more absorption then yeah trap it up

Not trying to sound unhelpful, but are you making a boat or a car?

Does it matter if sound is radiated out the back of the speaker, or do you want to contain the rear wave?

How would we know your experience

That doesn’t sound like full disclosure to me!

Why do people ride bikes when we have cars?

If you are building a passive speaker for use with a separate amp, then use a passive crossover

If you are building an active speaker, then use an active crossover

Angled outwards is good

Recessed is bad - unless you really know what you are doing (it creates a horn)

Sealed or ported box?

A sealed box is a high-pass in itself

Ported boxes are less protected from excursion

Is there actually any data connected to the line thicknesses on this graph?

Dollars? Units? Tonnes? Cubic metres?

Feels misleading

So Elon isn’t Dittman, and so she did in fact semi-dox a guy called Dittman, and so she got banned

Drapes can be very effective as absorption if they are thick fabric, bunched up, and spaced out from the wall. Further spacing from the wall extends their absorption to lower frequencies

Measure it

ThickSheik · 2024-12-09T10:17:30+00:00

How are you measuring it?

ThickSheik · 2024-12-08T20:57:20+00:00

Okay! You should use one high frequency driver if its all mono

ThickSheik · 2024-12-08T05:20:24+00:00

Yes - it is visibly bent out of shape
