So far, I've just tried a bunch of different combinations as far as plugging the Logitech in.

I have only been able to try it out in my living room apartment, so I have to try to keep the neighbors happy.haha

So far my wife Jen thinks they sound pretty good as a unit by themselves. Me, so far, I am not that impressed with the satellite speakers. But then, I love the sound of my Eon's. Since I have never used the z2200's, I have nothing to compare it with.

I have tried the sub with my JBL's and I see a good possibility here.

I've noticed that the sub is rather easy to blend with the JBL's. I was pleased at what it did for the acoustic bass. You could almost see the bass player in person. So, it appears to me that a sub is not all boom-boom, thump-thump.

If all it does is to provide me with a very good sub sound, then for me, that was really what I was interested in, especially because of the size, weight, 10" speaker and the 188 watts RMS power.

If I can get some good hi's and/or mid's on the sattelites to suit my taste then fine, if not the sub alone could make it worthwhile.

I think we will both be able to try it out more tonight, and possibly do some reading in the owners manual. (heaven forbid)

Is it typically just the bass guitar, bass fiddle etc. that comes out of the sub, or drums or any other parts?

I've noticed where I can have certain parts come out of the sub 1 and/or 2 output. I tried adding the bass drum and others, but it takes it away from the JBL's which didn't really seem to help the sound, unless it was maybe just the bass guitar.

I will continue experimenting with this for the kind of set up that I wanted. If it works out, fine, if not fine. Then I'll let somebody else try it their way.

I am sure the best test is on the dance floor, in a large room with a bunch of people soaking up the sound. I guess that will be the true test. Again, so far, it looks like the sub could make it.

I found that the best place for the sub to come out of is the headphone jack. Then I still have control over volume with the master volume control. The Loop out has a very stong signal, but I lose the ability to use the master vol control.

The Roland KCW-1, I'm sure sounds good, but it's heavier than I want to play around with.

I may still consider getting an EV sb120a or sb121a as a trial.

Experimental practice is what I call it, whether practicing music or trying equipment.

Best
