Why I'm not adding a sub to my 2-way monitors for music

Dear friends: Normally I don't re-vised/recheck my posts and now that I did it I made a mistake about " fan " that I wanted to mean the same as erik and writed a different word.

My apologizes to all fans and I will fix my mistake that was and is not my attitude about.

Dear @erik_squires : Several of those DBA fans are really that: fans and you know which one is ( non derogatory meaning. ) when with out ask nothing to the OP just posted it does not matters that the OP is looking for advise of subs to listen MUSIC at one and only one seat position. Obviously they need to learn but a fan normally is not abble to learn is not willing to learn.

Now, my advise to you for and for any one is to go for Velodyne due that even in the low bass we need to look for quality in that reproduction range and THD figure in that frequency range is quite critical because its tame all the other frequency ranges.

THD in Velodyne is as low as 0.5% where no other affordable true subs can get. I think that only Magico 40K each sub can even that Velodyne critical measurement.

I understand that in the past you used subwoofer. What made that you let it gone?

@erik_squires  : I re-read your link and is very clear why your sub gone:

" For my own listening levels and choice of music there is almost no reason to add a subwoofer,..."

We MUSIC lovers/audiophiles that are mere " mortals " have not your high technical knowledge levels, tools and certainly not your very specific and unique targets. 

What you did it is not easy to duplicate but been our targets different means your " information " is exclusive for you inside the overall limitations solution.

Your link is a learning one ( at least for me ) and tell us a different way to make " things ". Certainly not for me.

Btw, you said something like: " the subs are a rtone control " and what you did it too.

Dear @erik_squires  : Again re-reading your link we really can think what you stated there:  that your 2-way speakers ( system. ), that cut out at 40hz, and after all what you did it are performing at 20hz.

My take on all those:

the source recorded signal information certainly and normally goes lower than 30hz-40hz and even at 20hz or lower but your speaker can't reproduce what's in the recording that's different of what you achived in your room: two different things.

In the low bass range what you measured in your room is not what is in the recording: your room/system is reproducing something different down there that additional tame the other frequency ranges.

In my view you need subwoofers and not as a " tone control " but as a necessity for any 2-way speakers or even any passive speakers that crossover 150hz taking in count that every time we make that the speakers IMD goes lower we have a true quality performance levels no matters what.

In my case I like to listen what is in the recording, it's my main room/system target and for me can't be in other way.

With all respect I think you are not listening what is in the recording, you can't do it through the link wide explanation.

Maybe I'm wrong. What do you think?

Btw, in the same way that an amplifier or a preamp or a TT is not really a " tone control "  subwoofers certainly are not. Subwoofers are part of a speaker as are the tweeters or mid-range drivers.

In the old times Infinity top of the line speakers came with subwoofers ( non powered stand alone ones. ) and you can't buy it with out those subs towers. Today things changed a little and there are several speaker manufacturers where their top of the line models comes with powered subs integrated in the same whole speaker boxes and other separated as with the vintage Infinity. Certainly not a " tone control " audio item but a true/real necessity to reproduce MUSIC.

@erik_squires  : Yes, I know that no one can be truer to the recording that's a desired room/system target but I think that what you did it had a different target.

Am I wrong?
