Can we fit Dunlavy SC-VI in a samller room?

I strongly recommend not doing this. First you need to be at least 10' away from the SC-IV for good driver integration. With a 20' lenth, you can achieve this with the listener about 4 feet off the back wall and the speakers about 6 feet into the room. The narrow room can be dealt with from absorption and diffusion. It's not easy, but not insurmountable. The real problem is the bass. You have a lot of driver moving a lot of air in a small volume. By the time you get reasonable inertia on the low frequency drivers you will likely be overloading the room and have some really significant bass peaks and in general just more bass relative to mids and highs. You can (and would need) a parametric EQ. Our company makes one, the Rives PARC, and it's extremely useful, but we would recommend more appropriate speakers for that room size rather than trying to fix the inherent problem with an eq.

I second Rives comments.

And I third it. Great speakers, but they need a larger room than you have. You might look for a IV-A instead.

Sadly, Rives is right. I have the SC-IVa's in a 17'x30'x10' room placed on the long wall. Even for the IVa's it is recommended to be a least 10' from the speaker before all the frequencies (of the direct sound) come together spatially. My experience would say you might do all right at even 8' with only a small compromise and I have heard of them (IV's) being used in a smallish room with satisfaction. I have had to dampen and diffuse the wall behind the listening position because it is so close and I have other features in my situation (like a large opening on one end)that make it quite satisfactory.

With IVa's you just might make it in your room although it will not be ideal and you probably would need to treat the room...They are superb speakers, though, and a tremendous bargain if you can find them.

I also would dearly love to get the V's or VI's but unless I win the lottery and add on to my house it just isn't going to happen.
