Can you adjust the phase between subs and mains?

After building my speakers, I realized I couldn't adjust the phase relationship between my subs and the three front speakers. Even the high end processors only adjust for distance but not phase.

I just bought a gadget called the "phazer." I saw it in Tape Op magazine. It's a pure class A, discrete , solid state device and does what I need. I bought it two months ago but haven't connected it yet, a personal flaw I can't seem to get rid of .

Radial Engineering, made in Canada. It cost only $300 bucks so I need to get my but in gear to see how it works, or , wait to hear from one of you as to how good it is.

It's my hope to finish one of the projects I've started, but then, what's next?

regards, Ken

Ken,

Well that explains EVERYTHING !!!!

When I looked at your system I simply couldn't figure out why the roof of your house was still there. I mean why doesn't it simply blow off?

Be warned! With the kind of high quality parts and superb build of your speakers if you do actually ever get the phase precisely right between the subwoofer and your front three channels then as they say "Houston, We have lift off"

Ken,

The phazer device appears to be just a variable delay. I don't think it does any more than the delay setting in your DSP amp. If you want to perform phase compensation across the bass between the mains and subwoofer then you'll need to examine the phase of each speaker design (F3) and build phase compensation into the active circuits going to each speaker so they match.

At the listening position (far back) you have a lot or room modal reflected energy affecting your test signal - you might be better off nearfield to make precise phase adjustments - just two cents.
