Hej Troels,
Så, då är jag färdig! Känner mig mycket nöjd både med bygget och
ljudåtergivningen! Framför allt, enorm respons från basen vid höga
ljudtryck! Upplösningen kanske inte riktigt i klass med mina tidigare
Quad ESL-2805, men i gengäld går Accu att spela betydligt starkare med
och tycks aldrig ge upp. Driver med Bryston 4B-SST2 (2x300w) vilket är
en utmärkt kombination!
Har försökt skriva en text på engelska, du får gärna justera den om du
vill. Skickar också med bilder från bygget. Stort tack!
Mvh
Björn Jägerstedt
Hi Troels!
Here is finally my version of your Jenzen
Accu mkII.
Some small(?) differences in the baffle
design, just to fit into my curved cabinet. The cavities for midrange
and bass is vented (netto 17 and 66 liters), crossover filter placed
behind tweeter with an opening on rear side. Curved sides made of 3
pieces 9mm bendable plywood. Cabinet tilted 2 degrees (tweeter and
midrange baffle vertical) Veneer “Decoflex” flexible with paper
backside.
Some years ago I
built your “Ekta”, see my comments here:
http://www.troelsgravesen.dk/ekta_bjoern.htm
very good speakers for medium sized rooms!
Got then an offer of a second hand Quad
ESL-2805 pair, which I couldn’t resist. Great speakers for acoustic
music! Unfortunately my living room were to big for the 2805, couldn’t
play as loud as wanted. Also had a lot of trouble with broken panels
(China produced with bad quality), sold the Quads and searched for a
larger speaker, liked the sound of ceramic speakers like Marten.
Decided to make a try to build the Jenzen Accu
with similar look as my Ekta, since they were really appreciated by my
wife (and not least by myself!).
Result you can see below.
And I must say, we are very impressed of the
sound.
Take as an example, Mussorgsky Pictures at an
exhibition No IX (“The hut on chicken´s leg”) and No X” (Deutsche
grammophon 437 531-2) You can play really loud with enormous dynamic and
without significant distortion (of course you need an amp..).
Peder af Ugglas “Beyond” (Opus3 SACD)
Andreas Vollenweider
EST “Seven days of falling”
This is just to give you some examples of
music I like together with Accu.
Troels, thank you very much for a superb
design!
