Dunlavy SC-VI

I would second the comments of audioguy. I have Dunlavy SC-V's and use a Sigtech. I had a similiar dip around 40Hz. Since I listen to a lot of organ and late romantic music this was quite annoying. I used the RPG software ( Much simpler than the CARA) to explore various combinations of listening position and speaker positions that minimized the dip. I had three most promising combo's measured and used the SigTechto correct for those listening positions. In all three the speaker positions are the same but the angle of the speakers and the listening distances are different.

The first is 9' ft from the speakers where the Dunlavy's are time coherent. This is my listen alone postion. The second is further back and almost as good but alllows for my wife and I to liste together. The third is further back and allows several of our friends to listen with us.

I'm curious as to the sonic differences between the Vs and VIs? Dunlavy literature simply says the VIs go a touch lower, but both speakers are flat anyway. Do VIs have a different sonic signature? Do they seem more efficient? ... or what is it that makes them better than the Vs?

Because the design parameters are the same, they (V's and VI's) are very similar. The VI's don't really go any lower than the V's (at least in a normal room) but because of the radiating area of the bass drivers, they have more weight to the bottom end.

That does not mean that have increased bass amplitude. It means they move more air and so sound more like what bass does in a concert hall in terms of compressing the air in the room. In addition, because each of the drivers is larger than the counterpart in the V (except the tweeter), the VI's are more relaxed at greater volumes.

If you have the right room (and the money) I believe the VI's to be the better speaker. But given the V's are about half the price of VI's, (and 98% of the speaker)the V is the better buy. ....by a long shot !!!
