I use active analogue speakers (ATC System C6) all round with G68/98 driving via balanced lines.

To my ears, Trifield sounds like I imagined stereo should have done all along.
- The centre output locks the image and allows a larger sweetspot so that more than one person can listen optimally.
- The rear ambience lifts the image into the room.

The parameters need tweaking carefully and Meridian don't help themselves here by refusing to publish a "Dummies Guide to Setting-up DSP modes". It's essential to have 3 timbre matched speakers across the front and to set up the system middle depth and level to get the right bass phasing and reinforcement. There have been other threads on here about just this topic. Of the DSP parameters, the width makes the biggest difference to the soundfield and it is important to get this right for your room. I found it just "comes right" as you change the setting. The EQ setting is much more subtle in effect (to the point where I can't hear much difference). The depth setting in the DSP can be used to fine tune the bass.

Regarding the bass, yes, Trifield bass can sound a little reticent compared to stereo and I have +3 bass set in the Trifield preset to offset this (all set up by ear).

Trifield is one of the USPs of Meridian. If you don't use it then changing to other gear becomes easier...
