Dunlavy Audio Labs SC-IV


Greetings,

I've always been very interested in owning DAL SC-IV's, but given their current age, I'm a little concerned with making the investment in a pair.

I would assume the way Dunlavy matched/tuned drivers to achieve his results, would mean that just replacing a failed driver (if they're even available) with an off-the-shelf version would have a serious impact on sound quality.

Are the drivers in these speakers prone to failing and/or deteriorating over time? Are replacements available, and can you maintain the accuracy of the system with a standard replacement driver? Anything else I should know about investing in a system of this age?

Thanks for any and all input...I just don't want to invest in something that may be on the backside of the curve of its useful life.

Thanks everyone...What is a fair price in today's market, for a pair advertised in mint condition?
Seadweller, taking facts that they're not in business anymore, you'll still get stellar deal and save much more even after possible neccessity to replace drivers which are not pricey at all.
Already almost decade ago, once Dunlavy line decommissioned, they drop down the price drastically and your model could've been purchased for $4000. Now it's at or near half-way down i.e. @~$2k and worth worth worth every penny.
Yes, changing out a driver with a new replacement is a task most should be up to. Just pay attention to the wiring (taking a photo of the original may help) so you don't reverse phase.

As mentioned earlier, I'm not as familiar with DAL as Duntech models but I believe John not only tested individual drivers, he then tailored crossovers to match desired response for each speaker. I'm told Duntech keeps records of manufacturer so that a similar driver (spec-wise) can be supplied for replacement. I don't know if that practice was continued with DAL or not.

A few comments regarding set up if you do buy a pair. I believe use of spikes is room dependent and that relates to suspension VS solid floor, construction material, and floor coverings. Next, my Princess manual specified a 3 meter distance for listening to allow the five drivers to converge properly. A 10' equilateral triangle set up can work nicely. However, distance from sidewalls in important and should be a minimum of 3', more is better. Lastly I understand the DAL models may have been a bit easier to drive than similar Duntechs. My Princesses were rated at 90 dB but John suggested a minimum of 200 wpc "for musical enjoyment". ;^)

Good luck. I too believe all of Dunlavy's designs (Duntech and DAL) hold up very well and can offer great bargains in today's market.
I picked up a pair of the SC-IVs a couple of years ago for $2,500.00 which were not only functionally perfect but also without any visual flaws. I passed on a couple of lower priced sets that were around $2K. I've always felt that if gear looks like it's been cared for there's a better chance that it's in good shape sonically as well.

As a side note, I use the SC-IVs as the main channels in our high-end Home Theater room and use the SC-Vs as the choice for our reference 2 channel set-up. With the SC-Vs I have also incorporated the larger Dunlavy Sub (very rare) that incorporates four 10" drivers into an SC-IV size enclosure. Needless to say, the system is capable of moving some serious air in that room.
Here's the place Madisound recommends for Dunlavy repair, Meniscus Audio in Grand Rapids MI. They replaced rubber surrounds on two 10" woofers for me, fast turn around time and reasonably priced.

As far as I can tell the rubber surrounds don't deteriorate noticeably over time. My surrounds were damaged by "die Katzen". Both speakers are now covered when I'm not listening. 8^)

PS: I've mentioned this on several Dunlavy threads, the IVA is superior to the IV. I've owned both. So, if you're serious, definitely look for the IVA.
