Hello Troels,
After looking into my project folder, I realised my Quattro build turns
4 (quattro) and I haven’t send you any feedback to the builders response
page. So here it comes finally.
I started making the Quattro loudspeakers when I was a student. The
conditions were anything but good. My room in the dorm had 14 square
meters. Kindly I could do the grinding work on the terrace of the
student bar. The gluing of the boards and the final painting was done in
my room. As you can see on the photos I made a few simplifications in
the wood construction method. Maybe I will paint them, but at the moment
I still like the multiplex look very much. I was able to solder the
internal crossover in my university.
Occasionally I used a horn subwoofer as an extension into the deep areas
(still in the 14 square meter room). After 4 years of use I could hear
the loudspeakers in different rooms and currently operate them single
with a DSP (miniDSP).
But now to the sound: I am happy with the sound. The loudspeakers have
become my reference loudspeakers. Acoustic music generally sounds very
good. Actually, any music sounds great on them, even very loud.
Among other things, I listen to electronic genres and they do not have
enough depth for that. That's why I also use the DSP to rise the
gain until 30Hz.
I measured them in the student room for fun, but you can't use the
measurement. I use a 100W amplifier to fire them. The final pricetag
were 560€ per speaker.
I’m in love with the OBL-15 since a long time, because I expect a lot
from the open baffle design. Unfortunately I don't have room for the
construction at the moment. Will you introduce more speakers in this
direction? Judging by your review you liked them very much.
Many greetings from Munich
Phil
