Looking for my Final Pair!!

what did you can't understand?

What I'm posting is exactly what Vandersteen said.

The issue is to liberate/let it free the woofer of CW the frequencies in the low bass range.

That means that instead that the CW woofer plays/handled frequencies from around 35hz and up it will be free of the low bass frequencies and it will plays/handled frequencies from around 80hz-100hz and up in this way the IMD will goes lower in benefit of quality level of what you are listening today.
That's it, easy to do for you  because you already has subwoofers that you can use to  play the frequencies from around 80hz-100hz ( depending the choosed crossover frequency in the high/low pass filters. ) and below it.

If you can't understand it please let me know what you can't understand because it's not rocket science.

@rbrannen just posted  about the Legacy Focus XD, please re-read his post.

This is the Legacy:

that you can use full active with its internal amp or just active with low bass range. Please take a look the crossover frequency of the woofers and you can read that crossover frequency is 120hz ( active as a subwoofer. ).

I hope now you can understand the whole issue to improve the CW sound reproduction adding those subs in the rigth way.

Yes, I understand now...I have done that experiment with all of the speakers I’ve owned in my current home.  I have always preferred full range on mains and sub adjusted accordingly by ear 👂. With REL I have a wonderful blending which delivers deep taught bass.

@dave_b The use of a sub is good, but in order to really take advantage of that, you'd have to make sure no bass is getting into the Cornwalls. That's probably best done with an electronic crossover, which can easily muddy the sound, eliminating any perceived advantage (although there are vast differences in crossovers). So while Raul's suggestion holds water, it has that downside and it should be noted that it applies to any speaker that has bass information on the woofer cone. Its nothing that applies specifically to the Cornwall.

Dear @dave_b : This I posted in this thread 03-24. Where you can see and read about that external crossover to set up the crossover frequencies through a Xover:

""" In that thread I gave my advise to the OP gentleman as an alternative to those Wilson Alexx V:

with this Xover:

these could be the subs:

One way or the other almost all of you are " against " my posts about but please let me know which Cornwall IV owner has its set up using subwoofers not as bass range reinforcement but crossing at 80hz-90hz where the main speakers are handled from there and up? """

In my latest post you can read again about low/hi pass filters:


" easy to do for you because you already has subwoofers that you can use to play the frequencies from around 80hz-100hz ( depending the choosed crossover frequency in the high/low pass filters. ). "

You posted:

Please let me explain to me what I read in your post and please confirm if what I understand is correct or wrong:

so, that means that using a high-pass filter ( external or in any way. ) you made it that your main speakers ( any of the ones or all you owned. ) through its woofers have a crossover frequency at around 80hz-90hz meaning that those main speakers plays frequencies from 80hz-90hz and up and that through a low-pass filter the subs plays from 80hz-90hz all the way down to the very low bass frequency ( lower than 20hz. ).
So that the woofer of the main speakers never sees/seen/plays low bass frequencies, rigth?

and after your tests you prefer play in full range mode the main speakers using subs as bass reinforcement only, rigth?


Both solutions are different and give different quality of soun room/system reproduction.

Have I a misunderstood on your last post?

Thank’s.

R.

Yes...me likey my system full range!
