Hello,
I'm Olli from Germany and I'm into pure Stereo Music 100% but no AV stuff. So why I'm ending up here in this forum? (because of this Meridian Thread about Trifield:
Trifield AlternativesI'm very much convinced Tri-Stereo is a good concept also for music lovers! - Why?
Because it works for me VERY WELL! Maybe because of my room weaknesses basically? Maybe I like the (artificial) stage imaging, the more stable center when it comes to installing the real 3rd speaker at the middle of the "stage", maybe because of a wider sweet spot. After several room treatments, speaker and other hardware upgrades I am still remaining with this TRI thing! And I will stay with it for sure.
My first experiences I made and playing around with that Tri thing was with a NAJDA DSP where I first time heard of creating a real center out of stereo signal instead of relying on phantom center stereo image. Later I heard of the James Bongiorno Trinaural SP - purely analogue gear to subtract the center information out of the stereo.
I've used that analogue device for 3 or 4 years now. I like the stereo stage image enhancements very much and was happy with the result. But it offers only few (rather NO) options to play around with. Only levelling the center channel. Because the analogue maths and matrix is very simple. ;-)
L = L - 0.5 R
C = 0.5(L + R)
R = R - 0.5 L
Now couple of weeks ago I have read of Trifield for the first time (shame on me!!!) - and Meridian dealt with it SINCE DECADES! Whow - these equipment is available and it seems to be a bargain! To be honest Meridian isn't very present in high-end Stereo scene. But now it's time to open up mind for other TRI concepts - and I've read the paper of the origin of Trifield.
So, I've purchased a 568.2 for a little money. And my next experiments will exchange the Bongiorno analogue Trinaural with a Trifield setup with Meridian.
But I would like to share my whole Hi-Fi System concept to give a better understanding, what it looks like - how to integrate this Meridian Trifield DSP. And I'm really looking forward what you think of it!
Beforehand I need to state that I'm a little obsessed to the idea of having a neutral frequency response at the sweet spot listening position. I stick to the idea that the music producers is having the real idea of how his music should be coloured - nobody else - no Speaker and no other hardware supplier does have the right to change ANYTHGING - neither I don't have that right!
So, if this is the case - why not using some equipment producers uses in their studio!!! ;-) Mainly Speakers should have the ability to be as linear as possible.
Now ending up with main Speakers Genelec: Center 8351 and Left/Right 8340. (SAM Management room measurement System doing the BASIC room correction, phase correction & freq. response) Also very helpful is the Genelec GRADE Report that will be created with any SAM Measurement
GRADE Report GenelecSubs are not Studio equipment: 2 x Dynaudio 9S
Streaming/Pre-Amp NAD M66 with Dirac Live and newest Bass Management option. DIRAC Live now doing the lower end correction which is not controlled by Genelec SAM.

Sorry for that very long post...
