I have only had them slightly over one year, but I am loving them.
I hated them at first, but they have taught me, a veteran audiophile, of the importance of the room!
John Dunlavy wrote an excellent owners manual, and out of sheer desperation, I actually read it.
LOL, every time I improve the room, so do the speakers!
Go figure, huh ?
I bought 4 ASC 48 inch corner mounted bass traps I have to pick up, when it stops raining.
Can't wait to get these bass traps in my room.

I heard them many years ago, but remember they were wonderful. Enjoy
Thanks!
Long time owner of IV-A's and Aletha's. No speaker I've heard has ever given me as much day-in and day-out satisfaction as the IV-A's. The Aletha's go into action if the IV-A's ever crap out....which hasn't happened in probably 20 years now.
See ya. Dave
Especially for their time. However, I believe you may not realise what you're missing (perhaps a blessing in disguise).
I go to the shows. My boat doesn't get floated better by anything I hear.
No need for the show conditions argument, please.
See ya. Dave
That's understandable. The true purpose of "the shows" was for manufacturers and dealers to meet to discuss business. This has all changed in recent history. It's not easy to achieve good sound in all venues, but it can be done. One of the best demos I've heard came from a room using a DEQX system. There are a few other examples that come to mind that didn't involve DSP.
They measure well even by todays standard , better than many touted today , the D' Appolito configuration is still correct for doing a monkey coffin and physically aligning is still the best way IMO.
Doubt if in good shape they would sound anyless today ...
Nice !
I love my SC IV's
You may have read some of my previous posts regarding Dunlavy's speakers. I owned a pair of Duntech Princesses for 19 years. They were the older sibling to your SC-IVs, designed by John and built in Oz before his return to the US when he started up Dunlavy Audio Labs, DAL.
That was all some time ago but I continue to believe he was one of the premier speaker designers. For anyone with an appropriate room and supporting components his designs can produce very rewarding sonic results.
During that time I heard several systems with either Duntech or DAL speakers, both in homes and at audio shows. About the only area where I disagreed with John was his recommendation favoring long wall placement. I suspect that was influenced by the need to have reasonable distance from the speakers to the sidewalls. However long wall placement in most rooms results in the listener being very close to the back wall. For me that overloads too much bass information and detracts from the very good bass quality the speakers are otherwise able to produce. But I happen to know John loved bass! ;^)
One aspect which I do agree with is the need for adequate seating distance from the speakers to allow convergence of the multiple drivers in each cabinet. In fact the Owner Manual for my Princesses stated the response plot was recorded at 3 meters, rather than the customary one meter for speaker measurements. That seemed to be a critical clue. So I found the ideal set up was an equilateral triangle with 10-12 foot distances.
Lastly, proper utilization of ASC tubes can help almost any room in my experience. Good luck with your continuing refinements and enjoyment.

have had dunleavy SC IV s for about 20 years also.
primarily fed by audion 845 tube (24 watts) monoblocks. mckintosh 5100 integrated
when the audions needed service.
while the mckintosh did have punchier bass, it did not quite match
the tube fullness or subtlety of timbre. especially in voices. since we like opera, the audions
have never moved. but not to say that jazz or symphonic orchestras
are lacking.
in a fairly large room about 25 by 30, partially open on one side and
stuffed with furniture and things. so no large relective wall space.
i can sit close ( ~9 feet ) or far (~ 25 feet) , still, the speakers disappear.
When John opened DAL and redesigned a full speaker line up he utilized different drivers than those in the similar Duntech models. I experimented with various amps and my Princesses responded to power. I liked the sonics from VTL 300 monoblocs but I ended up with Halo JC-1 monoblocs rated at 800 wpc into 4 ohms. From the furnished load plot they dipped below 3 ohms at two frequencies and lesser powered tube amps didn't like that.
While I never owned any DAL model, from all I've read they can preform nicely with much less power. So I'm not surprised that your 845 monoblocs could work.

I had the SC IVAs for many years pushed with a MAD A400 (200 wpc , best solid state I've ever heard) and loved them. My room was shaped and large enough to follow John's recommendations to great effect. Now I insist on phase correct and time aligned speakers. I got such a good offer on the SC IVs that I sold them and got Reference 3A Grand Veenas also phase correct and time aligned.
Doubt those are Phase correct and time aligned....
I dont.
"Phase correct" (like "phase coherent") is a nebulous term for marketing purposes.
It has little meaning without further explanation regarding the context.
Dave.
The Dunlavy SC IV's really surprised me, as far as imaging goes.
Most very large speakers seem unable to "get out of their own way".
Not these!
They can get 3 dimensional, if the material permits it.
Got to know John when he was here in Canberra for a few years.

I am a Ham Radio Operator, and John Dunlavy is the father of a type of directional antenna we Hams use called a Log Periodic Antenna.
Nice guy if a bit precise, like me!?
Liked the Audiosphere model 3's I've had for years, and knew why.
