Entreq Tellus grounding
Take k-ohms measurement between the grounding terminal you want to add to your speaker terminal and every other terminal on the box you want to use for grounding. If it has no DC connection (open circuit) it may be safe to connect it to your speaker terminal. Take similar measurement at your...- CherylJosie

Entreq Tellus grounding
Likely true in most cases but as I have repeatedly indicated, it may still help address problems in some circumstances. I just am not seeing any such circumstances in the average audio amplifier that exists within larger audio system. So basically I am in agreement with you and that is why I...- CherylJosie

Entreq Tellus grounding
Well if we want to take the plunge into philosophy all I can say is that for me the divine begins where my understanding ends because everything beyond that boundary is mystery. Science seems to be the one 'religion' that best explains the mind of God to me, if such even exists. Try violating...- CherylJosie

Entreq Tellus grounding
Section entitled 'Loaded Words That Cause Misunderstandings' discusses the concept of shield, earth, signal grounds and the ground plane under an antenna etc. This is all very basic stuff but unfortunately for the non-engineer type the concepts are probably foreign and only marginally...- CherylJosie

Entreq Tellus grounding
I cannot justify the purchase of grounding solution for a system that cost less than the grounding. Ordering them solely so I can convince myself one way or the other would be taking advantage of the return policy for a free education as well as likely a complete waste of everyone's time...- CherylJosie

Entreq Tellus grounding
The paper linked to below does have something to say about speaker wires and RFI/EMI, but it takes an entirely different approach with twisted pair instead of grounding. It goes so far as to claim that twisted pair is the ideal speaker wire. Very informative but unfortunately somewhat heavy...- CherylJosie

Entreq Tellus grounding
Balanced cabling is probably one of the easiest ways to improve system CMRR while meticulous system grounding of pieced together components is probably one of the most difficult. How to improve grounding related s/n with components that are physically large and maybe physically distant also...- CherylJosie

Entreq Tellus grounding
Just checking in again after a couple days to see what sort of hornet's nest my comments stirred up. Hey people, something to keep in mind about me is that I am blunt and sometimes annoying. In my heart there is no malice toward anyone but if I am 'puzzled and amuzed' by something that seems...- CherylJosie

Redefine your budget room EQ 'flat' target curve to Harman's pro curve
We appear to be stuck in a cycle. I hope I can end it with this last post. Harman study concluded that smoothed and extended frequency response is preferable and that the preferred target EQ is not flat. That is direct paraphrase from Dr. Olive's slides. I am in complete agreement with these...- CherylJosie

Redefine your budget room EQ 'flat' target curve to Harman's pro curve
How flattering. Are you sure you want to elevate a novice like me to sticky status? Only been at this for two years as solitary practitioner.;) However the spirit moves you. Your forum. I am just glad to have a place to try out my wacky ideas.:) Thanks for fixing my account. I have been...- CherylJosie

Redefine your budget room EQ 'flat' target curve to Harman's pro curve
Not exactly. Audyssey curve also sloped down and it did the worst. It may have been flat in the bass but it attenuated the treble. It did worse than the curve that was flat all the way across. At least the other flat curve was deemed as good as no EQ. There could have been other reasons...- CherylJosie

Redefine your budget room EQ 'flat' target curve to Harman's pro curve
That is one of the most interesting simulation I have seen. Great graphics. I am unable to upload any more images for some reason so I basically cannot respond to the rest of your comments. I would like you to know that I support the Harman study and its stated conclusions. What I do...- CherylJosie

Tuning a low budget-ish apartment home theater
First, the system: Up top we have an acoustically transparent screen and behind that a Samsung LCD. The height channel speakers are Sapphire model SB 5.25" aluminum woofer and 1" polycell/hicell plastic dome tweeter. I have never opened one but I assume they are unbraced.

Redefine your budget room EQ 'flat' target curve to Harman's pro curve
Do you have a link to the user manual? I would like to see what it says about manual entry of room parameters, curve fit to the given room, etc. I am not seeing evidence of that. Harman defined 'most positive results' as being what pleases their trained listeners from among the choices they...- CherylJosie

Redefine your budget room EQ 'flat' target curve to Harman's pro curve
Oh yes, sorry I forgot to include one last point. The 3dB limits of correction need to be determined by how well the actual in-room response fits to the target. A bowl-shaped target not only allows for less power requirement to achieve the end result, but also allows for more extension in the...- CherylJosie
