achjimmy Posted April 25, 2016 Posted April 25, 2016 I heard a pair of these 20 plus years ago being driven by an ME amp. I thought they were glorious and got me hooked on quality gear.
lusk Posted April 25, 2016 Posted April 25, 2016 Nice dome midrange. Wouldn't see a speaker manufacturer these days reveal this kind of detail. 1
Sub Sonic Posted April 26, 2016 Posted April 26, 2016 Nice dome midrange. Wouldn't see a speaker manufacturer these days reveal this kind of detail. It looks like it is a speaker designed by ETI or Scan Audio. Scan used to be the importers of Dynaudio drivers, but it doesn't look like the project is from Dynaudio themselves. I do love Dynaudio drivers though, I have played with a few over the years and they are fairly easy to work with and sound nice.

Al.M Posted April 26, 2016 Posted April 26, 2016 (edited) Very decent kit build. The D52 midrange dome is a well built very popular driver used in many speakers like Duntech and Edgar horns. It's a shame Dynaudio stopped selling drivers to the public about 10-15 years ago, except maybe car audio. Maybe they got paranoid about people realizing that customers would start DIYing speakers instead of buying commercially made whole speakers at 10x the price and commercial speaker companies applying pressure on them to stop selling to the public. The D52 midrange is generally easy to find used. Would be good to turn that kit into a floorstander by keeping the same volume, making taller around 1m and shallower. Note the kit brochure claims about $2000 kit cost equaling a $10K speaker, which is also the common DIY speaker builder forum talk about the same retail vs parts cost ratio of 1:10 Edited April 26, 2016 by Al.M

davewantsmoore Posted April 27, 2016 Posted April 27, 2016 This speaker will have a really wide coverage pattern through the couple of octaves above 1khz. It will also have an enormous mismatch at the mid-tweeter crossover .... (ie. the 0 degree responses of the mid and tweeter are equal .... but at 60 degrees, the midrange is down 16dB relative to the tweeter). One thing to be sure though .... considered individually, each driver had marvellous performance for the era.
Resonance-2-Rythm Posted January 28 Posted January 28 (edited) Hi All, Not sure if this thread is still good after 8 years but I thought I share my experience here anyway for other members to use as reference in the future. These speakers came out when I just got to high school so I was not aware of their existence until I was in University. But they were never available to purchase as second hand in my state or maybe they came up once but there was no way I could afford them with my Star buck’s renumeration back in the late 90s. Fortuitously, I found a pair about 5 months ago with rotten foam surrounds (bass drivers). Their history is interesting; the original owner sent the set to a guy in the Goldcoast after 8 years or so of owning them and the original cross over was changed and converted to bi-wiring. However, the owner did not like it and so he got Speakers hospital (VIC) to rebuild the cross overs to the original specs but with SCR caps, Ortofon cables, air core inductors (?) and convert it back to single wiring configuration in 2014 (date of the cross over board). I got 4 bass drivers re-foamed recently (2 with blue labels and seem new) and hooked them up yesterday with my Accuphase and they sounded wonderful. I could not believe how good they sounded compare to the newer speakers. I was surprised how deep the sound stage was, smooth sounding and those tweeters, even though they were ever so slightly prominent but still sound sweet and extended. Whoever designed the cross over on these was a talented person as they kept up with the time. I couldn't help but wondered if they sounded this good back then. If they were then really we have not moved that much in speaker development in terms of sounding of course. I also, acquired a spare set of each driver so perhaps I could get someone to build a big mirrored floor design like Duntech princess one day. Btw, they need to be lifted off the ground to be most effective. Edited January 28 by Resonance-2-Rythm add photos 2
