Dunlavy SC4 Speakers

It started with the original Dunlavy IV, then towards the end of that run John made improvements to this speaker. He did not make any designation changes, but simply referred to it as the Dunlavy IV improved version. Shortly after this, he made additional changes that could not revert back to the original SCIV and therefore named it the SCIVA.

It has been such a long time, my memory fades....I cannot remember if all three versions say Signature on them or not. Mine are the SCIV improved and does says Signature on them.

I'm sorry that I cannot remember more specifics on all of the three versions. What I can say is that any of the three are fantastic speakers. You seriously can not go wrong with any of them.

I'm not an authority on DAL models, but I did follow their progress because of owning Duntechs and my respect for John.

I thought all the DAL numbered (Roman style) models were preceded by SC. I don't remember that he produced a special line of Signature models.

The change from SC-IV to SC-IVa was the most significant upgrade. It was in response to a Stereophile review of the SC-IV which was favorable except for bass extension. That was likely the only time anyone criticized one of John's designs for lack of bass. The SC-IVa apparently did produce a more extended bass range.

I owned IVs and currently own IVAs. IMO the IVA is definitely a superior speaker. The IVA also cost twice what the IVs did.

I've been an SC-4(not 4A)owner for over 17 years. An almost exclusively classical music listener, I've never been less than satisfied with its bass performance. I've also heard some others refer to the SC-4s as being bright. With the right room setup and associated equipment, this is not an issue...Incidentally, list price for the SC-4s was $5000. List price for the 4A was $8500, not $10,000 as Rja asserts.

Sorry, correction: SC-4A in oak only was approx. $8000; in rosewood or cherry, approx. $8500.
