Nice link on the live performances and sound reproduction
article.
Too bad my music and HT is all studio edited sonics
If I do find some live recorded music that I like, chances are
the capturing of the fine music was not it's best due
to the endless variables of trying to record it as
heard live.
Think outside the box
This is your signature, which happens to be my
views on sonics.
/random babble
/proceed with caution
/ personal views only, results vary with different listeners
My driver matching methods is 99% listening
and 1% specifications.
Many people talk about the "famous" designs, but
how many heard them? Or do some people just
repeat what other people say because of name
branding of the speaker ???
Before committing to building somethings, it would
be nice to know what the individual drivers sound like
*or* it would be nice to hear the beast before hand
to make sure the sonics are pleasant.
My methods are crude and expensive and of course
limited. In order for me to match up drivers, I create
a list of suspects and buy one of each. That is 1%
of the work. Next comes the 99% of the work,
listening to these individual drivers to hear what
their performance is and then trying to find a mate
The only thing I can share is my personal template.
I like;
Tweeter (no matter which one) operating ~2.0khz - 2.5khz.
Midranges high pass operating from 300hz (plus or minus
200hz)
Midrange low pass operating from whatever tweeter crossover
is setup from above.
I don't like tweeters crossed over too high, they start
sounding watered down. If I can't find a tweeter that
can't operate at least down to 2.5khz, I don't bother using it.
I prefer to find a midrange that sounds pleasant up to 2.5khz,
but doing so usually results in a loss of bottom end,
so I end up crossing it over high pass 300hz give or take.
The midbass energy from this type of driver is not enough
for me at a low crossover point. On the other side of the
fence, some people want a midrange/midbass combo driver
that has capability to go low, let say, 80hz, but they lose
the top end and need to resort to tweeters than can
handle 1.5khz - 2.0khz. Essentially, you have pick from
both evils, trying to find the lesser evil.
Woofers -> Typically, it's hard to find a nice sounding
woofer that can low pass 300hz to mate with the
midrange, especially if it's a large woofer in a high powered
application. I draw the line at 80hz - 100hz for the
common woofer unless I find the special woofer that goes
higher.
This leaves the nasty midbass gap between 80hz - 300hz,
this area is very active in music also and is the region
that gives people headaches trying to find the elegant
solution.
Since my lastest concept design is high SPL, the solution
for me was to use Lambda TD woofers to operate up to
300hz. Insert another subwoofer if needed for uber
low end, perhaps low pass 60hz to complement the Lambda.
3 way design + sub.
Pass Labs has an elegant 4 way design, the Rushmore.
100% fully active. Rumor has it, that is uses the Raven 1,
PHL midrange, and 10" PHL midbass and the 4th speaker
(woofer) is unknown. This design methodology almost agrees
with my tastes, except I think they operate the tweeter
much higher, personally, I wouldn't use Raven 1 for my
tastes, the rest is very sound. The last thing I don't like
is low powered amplifiers. The low powered class A amplifiers
would not agree with me except maybe the tweeter amplifier.
If I had that speaker system minus the amps, I would
insert some amplifiers with 200-400w class ab, on each driver.
For an exotic great sounding system, I think;
Tweeters:
Raven, Esg, Stage Accompany
Midrnage:
PHL, Focal Kevlar
Midbass: only if 4 way design (like Rushmore).
Woofer:
Lambda TD12 or TD15 (4 way design not really needed if Lambda
TD is used)
The Lambda solved my midbass problem.
I'm using the SA planar, very exotic.
PHL 8" midrange.
This is sonic ear candy for me

Found this information on the range for human voice
These are the ranges demanded in classical opera, hence the decimal point accuracy...
Type of voice, Frequency range Hz
Bass, 87.31 - 349.23
Baritone, 98.00 - 392.00
Tenor, 130 - 493.88
Contralto, 130.81 - 698.46
Soprano, 246.94 - 1,174.70
I guess these are the primary frequencies and you probably need to take into account 2nd and 3rd harmonics as well.
Therefore from 80 hz to 3524 hz

As I saidearlier, I used a pair of Tang Band 3" drivers and I am EXTREMELY pleased with the sound. Of course they probably could go lower on the male vocals, but I honestly havn't once noticed anything other than near perfect vocal reproduction on every movie I've watched so far, and they aren't remotely broken in yet.
