DTQWT, built by Sorin

Hi Troels
Finally my speakers got some real wood veneer (Zebrano) with 3 coats of mat lacquer. I'm very happy with the result. I've made also grille cloth protections for front and back. On back I used also a metal grille and felt material. Due to the fact that my brother is trying to build some of his own speakers: 3 way with Silver Flute midrange/bass an a Morel  tweeter, I've purchased a measurement microphone (Dayton Audio UMM-6 USB) and an external usb sound card (Behringer) to do measurements. Having this on my hand I've installed REW software on my laptop and made measurements to my DTQWT. Please find attached the results. Tweeter attenuation is 1 ohm, frequency response measured for three distances: 0.5m, 1.0m and listening position (aprox. 2m). These are my first measurements. Please fell free to comment. Thank you, Sorin.
