The reciever in question, the kenwood vr-6070 (I know, kenwood isn't fantastic, but i've been very pleased with it) is rated at an 8 ohm impedance, would running a vp150 (6 ohm impedance) cause any sort of problems? Or should I just stick with the vp100. The fronts will be m22Ti's, with qs8 surrounds and a Hsu VTF-2 sub.

The 6070 is a fine receiver and was a bargain. It should handle the VP150s with ease, and part of the THX certification is driving 4 ohm speakers, despite the officially required 8 ohm rating.

I wonder everytime I watch a movie with my pioneer vsx-41 if getting the 6 ohm vp150 was a mistake. The center just doesnt have the impact of the rest of the speakers. I thought it would be louder if anything since it was a lower impedance.

Have you compaired it to an 8 ohm front? Has anyone else had this experience with the vp150 and tracked it down to impedance issues?

great question about the impedence on the center channel. I'd be interested if it's been a problem because I have the VSX43

The lower impedance of the VP150 should not affect the sound quality, as long as it is properly calibrated with respect to channel level and delay. As long as the receiver tolerates the 6-ohm load (meaning, exhibiting no thermal or over-current shutdowns), the speaker impedance itself cannot be the cause of the alleged sonic "problems" if any.

Incidentally, my VP150 never prominently "presents" itself -- the only way for me to tell that it is working is to move away from the "sweet spot." Without the VP150 engaged (and in the phantom-center mode instead), the dialogs will collapse to the side. With the VP150 active, the collapse does not happen and the center image remains anchored correctly even from off-center listening positions. And this is essentially the only thing that my VP150 provides.

I would be unhappy if I actually "hear" my VP150 working.

Marcus, sushi makes an excellent point about not wanting to actually "hear" his VP150 as a separate source. This assumes of course that you've calibrated it so that its individual volume when playing alone matches that of the other speakers.

A similar point applies to subs; although many set the level too high, the sub shouldn't be "heard", instead the impression should be that the other speakers are putting out more bass.

I totally agree that I dont want to be able to hear any one speaker...but I do want to hear dialogue =)

I like most people around here got the Radioshack SPL meter to set everything up, I just did not like how quiet the dialogue was so had to turn it up a couple notches. I can still say I dont "hear" the center though.
