Dunlavy SC4 Speakers

Hi Drubin,

Remember that old saying?....."don't fix what's not broken".

If you have the magic right now, why mess with it? John Dunlavy was one of the greatest speaker builders of all times, in my humble opinion. He could take inexpensive drivers, match them, and design crossovers that were custom to those specific drivers, and create "magic".

I've owned my SCIV Signatures for a very long time and have no desire to change anything about them. Why? Because to my ears, they already have the majic that you referred to. I am not going to pretend that I know more about this "art" than a man like John Dunlavy!

Sure, I could change parts out and get a different sound....but will it be better? I doubt it. It really doesn't matter though to me as I love the sound I am getting right now.

Take the money you'd spend on all the parts/labor/time and buy more music and continue to enjoy them.

Just my three cents worth.

How do you tell the difference in the models of the SCIV's I hear there is the original then the signature series then the IVA . The set I picked up was said to be the original first run edition. However while setting up and moving the speakers around looking for the best position I noticed that they do say signature series on them. When I did some researching some say that all 3 models will say signature series?

This is all off the top of my head and time may have compromised my memory on all these particulars, but I seem to remember Dunlavy changing drivers (woofers?) and tweaking the cross-overs accordingly, on the SCIVs at one point. The SCIVAs are a different and better speaker altogether, and no the SCIVs can't be upgraded to SCIVAs. I'm not sure, but I don't think the "Signature" nomenclature really means anything.

Unsound. Is there any way to tell what woofers I have without taking one out? Are there any visual things to tell the two woofers apart?

Every model made by Dunlavy that carries the "SC" in it's name is "Signature". That's what the S stands for!
Dunlavy changed a few drivers on various models over the years but the only one significant enough, according to him, to warrant a different designation was the SC-IVa.
There was a change in the woofers of the IV before the SC-IVa came out, but it was hardly worth note. Of course, you will find many people who disagree with me regarding any performance changes but you'd be wise to take it with a pound of salt.
Bottom line..... All Dunlavy speakers are world class. Worrying about which "version" of a model you have is a waste of time.
