Hi chez

I found the same issue with Trifield and my 561 with no sub. The same issue is there with my 568.1 and a sub, but varies in degree with programme material. Nonetheless, compared to "direct" there is always a noticeable lessening in bass, but what you gain is an increase in presence, focus and musicality IMO. I reckon it's a worthwhile trade off, and Meridian themselves do talk more of Trifield being ideal for female vocals and simply recorded material in their handbooks. I have to agree in that respect...it's better with simple vocals and folk music, and in that case there are no trade offs. They recommend "Music" for multi-miked studio rock, although I still prefer Trifield, sometimes with a few extra dB of bass via the tone controls. When all is said and done, it's still a DSP to produce something that's not there...the centre channel, so I accept the compromises.

Regards

George
