Do you think you need a subwoofer?

With a Mini DSP 2x4 you can control up to 4 subs on line level. Food for thought . I am going to try it soon

I use Vandersteen 5A speakers.  They have built-in subs that are driven from their own amps...my main stereo amp drives the mids/highs.  This frees up the amp from the power hungry subs and permits it to just loaf with smile.  Two subs are better than one - they better fill in the lower reflections of the room

Dear @noble100 :  """  You achieved accuracy, neutrality and a low noise floor via component selection and your regulators.  I achieved this mainly through a change from a class A/B amp to a pair of class D mono-blocks.  I believe my mono-blocks have built in regulators that conditions the electricity prior to introduction into the amp's input stage. """

well, my ML monoblocks are fully regulated input to output and I can hear the improvement of my today regulated electrical lines. So, you could try/test it.


"""  You have achieved good low bass in your system by fine tuning the positioning of your 2 Velodyne subs over a period of years and I achieved it through the use of the 4 sub Audio Kinesis distributed bass array system following their progressive setup procedure.  

     The important thing is that, through slightly different means, we've both achieved good  bass response in our rooms. """


When I bougth my Velodynesmy target was to have a thigt er and more precise low bass end with lower overhang than my main speakers but over the time and even that I have it my personal finding in those times was that existed not an additional benefit in the system subs integration but a main benefits even more important than the low bass stand alone subject and that main benefit/target was and is explained in that link that I post here again. This is for me my real discovery because in those times I was unaware of the JBL or Geedes multiple subs white papers/options and certainly not what you posted here and are using at your place:

https://forum.audiogon.com/discussions/do-you-think-you-need-a-subwoofer/post?postid=310058#310058 


Years latter I have a dialogue/discussion with Mr. Geedes in other forum from where I was banned ( people are not prepared for me. ).
Well, I shared that link experiences but he did not cares about, he only talks on for what him was the main target: low bass.

I think that to have a reall good  system bass managemnt through subs is an " additional " benefit to what I'm talking about.

Obviously that today things changed for the better till not only that noise floor or accuracy but the must important issue for me is that when BASS System MANAGEMENT is rigth then there is no need of almost any room treatment because ROOM DISAPPEARS ! ! !  and this is the AMAZING and new experience for every one ( like you. ) that experiment/try with.

As you can see almost no one of the regulars in this forum posted in the last weeks in this thread and this fact speaks for it self.

I can remember audiophiles excuses to not try the subs experiences, everyt kind of excuses and I remember very clear this one with Avalon speakers ( I remember this same kind of excuse with other audiophiles and diferent speakers. ):

" I don't want to use the high pass crossover my Avalons in a frequency range where its shines. """, but something like this was the same with a Magico owner that has problems with these speakers. people just don't want to grow up and prefers stay in his " confort chair ". Even my cvlose friend Guillermo who owns top Soundlabs gave me similar answer years ago but here today are using a pair of subs with that great Soundlabs he owns!.

Dear @noble100 :  I was trying to find out information of what tipycal level of THD has a bass/subwoofers configuration as the one you have but it does not exist something about.

Do you have that information or a link with?

regards and enjoy the music,
R.

Dear @noble100 : I think that that information does not exist for a specific room/system.

In the old JBL papers the main subject is a room evn bass: no problems by standing waves, almost flat bass frequency range and the like but never gave any THD information and this for me is a critical issue.

Room does not disappears only because bass management is rigth but only is the bass and overall syatem distortion in the room is really low.

That's why I ask about.

It's really " curious " that when we talk about manufacturers of subwoofers for home stereo systems no one gives the THD of their models and I know this because I call/email almost all of them and no one return with that information.

Velodyne 15/18 has only 0.5% THD at 20hz at 120db. This sole figure is just IMPRESSIVE by any standard.

By comparison the touted JL Audio subs that never gaves that THD figure were reviewed by ST and Atkinson gaves it at 6%. Yes, it's a very good looking unit but nothing that can not even the Velodyne but is far away from it. Sorry for the owners that have that very high distortion levels in the main home system audio bass range.
Now, what happens with JLA is not only them almost all subs in the market but Velodyne has problems there.

THD, between other things, is one spec critical when we are buying subs.
