I think 8-8-1 will be very good configuration all together.
Make sure it stays sufficiently far from back wall. Point the axis toward to your shoulder and I think it would
be fine setting. Turn off tweeters and Fundamentals channel and set right
balance between MF output and upper bass output. You might use RTA but it will
not be very useful for you in beginning and you need calibrate RTA for your speakers
and it will take for a while. It will be
approximately 1 dB freedom for MF channel where it still be “flat” and you will
need to find right configuration. Playing with axis targeting and MF attenuation
you will need to find right balance all together and right amount of “strings bite”.
You will initially most likely will go for a bit harder “strings bite” as it defines
“quality” in most of audio. As time goes by you might want to get more lush and
soft sound from you and to get harshness only when musicians and music is called
to it. The subject of right “strings bite” is very complicated and I can write
a whole book about it. In most of the systems it is also is contingent upon
many factors. Macondo has some own factors as well. The acoustic treatment of
the room, electricity quality, the axis direction and many other factors are
common. In Macondo, specifically will be the selection and operation mode of
the output tube for MF, the type of OPT, the inductance of the MF attenuator,
the type of the MF tube loading, the type of the diaphragms is use with S2
driver, the listening distance and many other factors.
Regarding the dual 15"
midbass boxes. They are $45 each,
from eBay by the companies that do chip boxed for car audio. I ordered them when
kid where small, did not sleep at night and I had no time to deal with it. The
point of the experiment was to see if a pair of Vitavox 15 drivers per channel
will be able to have a reference output to match the rest of Macondo. The experiment
showed that it is truly perfect in dB sense. In term of overall sound, it is a
bit more complicated. I very much like upper and lower region of my new midbass
channels but I do not like the lower end. It is not bad lower bass but make the
lower octave to sound the same in all music. It is not as bad as a typical subwoofer
but it is not as different as I am accustomed. Also, it is very much not integrateable
with my ULF channels. The ULF does add a lot to the sound but at the same time
makes lover bass even worse.
Now, it is easy to blame undersized
midbass boxed for the “tightness” that I experience and it is not dificalt to
get larger boxes and better made. The reality is different and it might be many
other factors screw with my lower bass, not only the boxes. To name a few: the Vitavox
15 drivers might not be a right choice foe sealed topology, the damping of the
boxed was wrong type for the drivers I use, the Milq LF channel is not properly
loaded by dual Vitavox etc etc etc…
To test everything and to
find right solution need time and I just do not have it. For now, I use the car
audio boozes for $45 and am glad that they give me right dB output. As time
goes by I will experiment with it more and will find a better solution. I am
not completely abandon the idea to have a midbass how made in there…Rerurn to Romy the Cat's Site
