I believe Dan Roemer of XTZ was involved in the engineering of the DCM TP and TFE series
The TP160S woofer can take a lot of power -- While the tweeter lacks a little air, they really have some good imaging, the soundstage is really nice. And they have some nice tight and controlled bass. While not dead neutral flat or perfect; they are not really aggressive, harsh, or edgy (but some female voices can sound slightly hooty) .... They do a pretty good job on Take Five by Dave Bruebeck ... and I can listen and enjoy higher female voices, brass, piano, violins and not want to throw the speakers out .... these are not bottom entry level speakers ... and yes I will take them over the likes of Sony Core, Q Acoustics, Cambridge S30, HTD Level Three, Infinity Primus, Polk RTi4, Boston CS, CR series and some others.
