Searching for matching(?) Subwoofer solution

Maybe problem is that each one of us usually can think that what we own is the " best of the best ". That does not exist quality levels where belongs each room/system

There are low/poor quality, lower quality, medium or so so quality, top quality and the like. Quality is a ladder that where we need to learn how to go up step by step.

I already left clear with his own facts/statement why noble100  system  is a poor quality level  and he needs to learn about that ladder quality steps/treads because many of us just do not want that low qualityn levls.

Knowledge levels through first hand experiences helps a lot to learn about..

Hello rauliruegas,

       Did you read the responding post I directed to you yesterday 8/15/19?  If not, here is a direct quote addressed to you from my earlier post:
"I agree with you that using better quality subs will only improve the quality of bass reproduced. I think this is true whether one uses a single sub or multiple subs."

     I appreciate, respect and understand the importance of good quality in almost everything, especially in things I decide to purchase or am considering purchasing.  What I don't appreciate, respect or understand is why you believe you made it clear to me, with my own facts and statements, that my system is of poor quality.  I must have missed that deftly executed revelation you so kindly presented to me, using my own words no less.  Well played, mi amigo, well played.

Later,
Tim

Btw, first step/tread on that music quality learning ladders is to attend as many live music events we can, second can be to listen as many other home systems as we can and other truly revelatory thread/step is to listen live music seated at near source position that’s where normaly " seated " the recording microphones ( 1m to 3m. ) and we have to do it not one time but several times.

All those steps are a learning lessons to understand the true meaning of quality in the MUSIC/sound reproduction on each one of us room/systems and at the same time we will use those lessons to through the time be up-dating/grading our system., fine tunning the system.
Again, I’m talking of systems dedicated to listen only MUSIC not along HT option.

In general I agree with what you wrote, so let me just toss out a few comments.
" We all are unable to localize deep bass frequency soundwaves..."  

My understanding is that’s generally true in a room. The figure I use is 80 Hz, rather than 100 Hz. I think Floyd Toole uses 80 Hz. This doesn’t necessarily mean that one cannot detect the location of a sub which is crossed over significantly lower, say at 40 Hz, because crossovers are not brick walls, so upper bass/lower midrange energy can give away a sub’s location if it comes through loud enough. Therefore in my opinion a steep lowpass filter on the sub helps to hide its location.  

"the bass is summed to mono on frequencies below 100 Hz on all vinyl and cd recordings."  

I wouldn’t say "all", but I would say "almost all". (If we’re talking about a Swarm/DEBRA system, a second amp can be added to give you true stereo bass).

"Our brains are able to associate the fundamental deep bass frequencies reproduced by the subs, that are not able to be localized, with the deep bass’s higher harmonic frequencies, that extend well beyond 100 Hz, which are reproduced by the main speakers that are able to be localized. This psychoacoustic association allows us to localize the deep bass in the soundstage, for example the kick drum is located in the rear center and the upright bass is located in the front to the left, which would not be otherwise possible without this psychoacoustic association our brain’s are capable of."

I agree.

Hleeid,

Before you do anything I would suggest reading http://www.soundoctor.com/whitepapers/subs.htm I think you will find them very informative.

A question for the DBA folks; How do you get the mids and highs to spread out evenly through the room to match up with the bass at all locations in the room? Also does a DBA affect impact?

Thanks
