Shadorne,
Phase was one of the most important points I had to address when building the speakers. The more drivers you use, the greater chance you'll have phase issues.
All the drivers in the three front towers are time aligned with respect to each other. By using only active crossovers throughout I greatly reduced the phase anomalies associated with passive xovers. It also made level adjustments much easier without wasting power.
Having the subs behind the front towers presented a phase issue that was addressed by the time delay settings for each speaker by the Krell processor.
While it enabled me to dial in the distance from my ears to each of the speakers, in feet, it offered no fine tuning. The Phaser should be the fine tuning device, when I finally get around to hooking it up.
The subs xover at 60 hz at 24 db per octave. An spl measurement for maximum level using a 60 hz signal at the listening position should do the trick. How it will sound at any other spot in the room will be interesting but inconsequential.
Using a self powered sub with the adjustments incorporated has got to be the cat's meow but being a DIY guy, that option didn't exist. I'm looking forward to hearing the difference the Phazer will make, I think I'll try it tonight.
