Do you own Dunlavy SC-IV's AND a yardstick ???

Pls1, Dunlavy V's and Sigtech sounds (reads) impressive. May I ask if the Sigtech maintains phase coherence while "correcting"?

Yes. The correction is in the time domain. "Flat" frequency response is actually the "side effect" so to speak of maintaining the time coherence. If you Sigtech correct a non phase coherent speaker more of the processing power goes to correcting the speaker and not the room.

With the Dunlavy all the Sigtech processing goes to minimizing the room effects. With Dunlavy providing the actual frequency and impulse traces for each speaker you can see how close you can come with your in room measurements.

My approach was to first do the best I could in buying a house with a suitable room. (We looked at 500 houses) Then got the best room placement(first approximation with room software). Then basic room treatment(not so basic subfloor reinforcing). Then use the Sigtech correction.

The final result is I've pretty effectively eliminated my room and maintained impulse/phase coherence with flat frequency response from the high 20's to 10K. I could get them flat to 20K but as I said above I prefer the room roll off

500 Houses! Wow! You are a true purist. I love it! Would love to hear your system. What else is in the system?

THANK YOU ALL for your responses. I GREATLY appreciate it !!! Sean
