Four Samples to Test your new Subwoofer
Make sure to
start with low volume settings and work your way up!!! The
recording is the weakest of the 4 clips, the others (Telarc recordings)
have infrasonic bass at or near maximum CD recording levels!!!
Telarc makes some excellent organ recordings. As many people
already know, Telarc does not pass the signal through any processors -
compression or equalization on their recordings. I have
Murray on the Ruffatti Organ in Davies Symphony Hall in San
Francisco. Telarc has recorded him numerous other times,
too. I also have an RCA Red Seal sampler disk with
Symphony No. 3 in C Minor by Ormandy and the Philadelphia
Orchestra. For those who may not know, this was the theme
throughout the movie, "Babe." Remember that talking pig
movie? Following is the opening chord from that disk (it's
chord in a lossy format as I don't want to be sued by the Gestapo, I
Forth Reich, I mean the RIAA for trading songs. This is not a
whole song, it is one chord to test
your subwoofer. Do NOT contact me trying to obtain
the whole thing!!! I WILL NOT DO IT!!! Definitely buy the
CD's of these samples if you like them.
Saint-Sean's No. 3
great piece. Besides, my website will start saying bandwidth
exceeded again :-o
add any more length to them.
Sean's Symphony No. 3 clip - opening chord
The stronger notes are 32 Hz, 49 Hz and lower level 16 Hz!
actually ends even stronger, get it.
Here's an extra special treat for your subwoofer - A couple of Dinosaur
footsteps from Jurassic Lunch:
Lunch clip - Dinosaur steps
Wimpy subs need not apply!!! Start with your volume
If the sub does okay, you can crank it more and try it again.
Warning, those footsteps are strongest at 10 Hz and 21 Hz depending on
which footsteps you hear or rather feel. All high level
except for the forest sounds (birds, etc...) are below 28 Hz.
Only the last footstep starts bringing up the 30 to 200 Hz band a
little. The first footstep is at 2 seconds. The
(or steps - it's a bit drawn out) occurs at 5.5 secs (with 25 to 30 Hz
frequencies joining in at 7 to 8.5 secs). The last footstep
starts in at about 10 secs, with 12 Hz and 23 Hz tones joined by low
level 30 to 200 Hz sounds a half second later.
Most subs will play the last footsteps in this clip (at 10.5 seconds)
okay. It's the first two (2 sec. and 5.5 sec.) that most subs
miss. They may be flapping wildly, yet not giving any tactile
sensations. Trust me, if your sub reproduces it you will feel
infrasonic shudder. I almost hear a "Waaah" sound when it
almost like an infrasonic burp. I know you can't hear that
it's more of a sensation - I don't know how to describe it.
second footstep(s) make a sort of "Waaah-Waaah" sound
(sensation). Again, it's hard to describe, but you'll know it
it's there. This clip comes from Telarc "Surround Sounds"
disk. It originally comes from "The Great Fantasy Adventure
Album." There is more to this track if you buy it.
only given you the initial 3 footsteps. They're at a
distance. The footsteps get louder
and trees start snapping. Finally, the dinosaur roars then
chomping down on someone, er, something. (This is suppose to
simulating the dinosaur in Jurassic Park eating the man on the
toilet. Ewwww, Yuckkkk!!! You hear the bones
kindling. Then finally, he swallows, and burps an infrasonic
burp. Note that the location of the footsteps is different on
actual full length track, starting at about 14 secs, 18 secs, then 22
Chiller Clip - Rolling Thunder
Another good Telarc sample is Chiller which includes their
loudest recording to date - lightning strikes and the reverberating
thunder! The initial crack is recorded at the maximum level
(not included on this clip). This is the sound of the thunder
"booms" as they echoe, and roll through the
hills. The first boom has strong 15-18 Hz and slightly lower
Hz content and general rumble down to 10 Hz at the 28 Hz
The second boom has strong 13 - 26 Hz content.
wimpy subs need not apply.
Terminator Theme clip
This is a third clip from Telarc. It is from the Terminator
track. I have included the ending which ends with a loud
"boom." However, the boom isn't the big finale.
There is an
infrasonic "kick" right after the initial "boom" at about 3 1/2 seconds
into the clip that has strong 16 Hz content which gives away to strong
11 Hz and 22 Hz content at 4.0 seconds. The 11 Hz kick is
strongest with the 22 Hz "kick" about 8 dB down in level. Do
need to say it again??? (Wimpy subs need not
Basically, this clip gives you an infrasonic "kick" that wants to knock
the air out of your chest. Well, maybe a slight exaggeration,
you know what I mean - you can feel it in your chest. You
feel it at loud volumes, but again, start at low levels and increase if
you feel comfortable that your sub can handle it.
Some other low bass disks are the soundtrack from Titanic (it has much
mid-20 Hz content), Sarah McLachlan - Surfacing, and of course,
Telarc's recording of the 1812 Overture with it's Digital Canons
reaching down to 6 Hz! Much Jazz is recorded with good
bass. There are also a number of Demo disks with well
Jazz available from some audio manufacturers such as Boston
Acoustics. Some movies with good bass are The Matrix, The
the Rings movies, and Star Wars - Attack of the Clones, especially the
opening scenes of the flying wing spaceship and it's explosion on the
landing pad (high level bass from 10 Hz up to 70 Hz ).
also an Imax DVD called "Destiny in Space" narrated by Leonard Nimoy
(Mr. Spock) which has a ground zero recording of a space shuttle
launch! Well, maybe they're a few hundred (or thousand) feet
away, I can't
imagine any microphone surviving 185 dB!!!
If I get some more time, I may put the StarWars explosion on here or
maybe the space shuttle launch.
Oh, BTW, I can play those dinosaur steps with my volume at my normal
maximum point (which is about the 12:00 position) or even a bit louder
than my normal maximum listening level. It has much more
than the mains. As I stated on my Subwoofer
page, I can ignore those Telarc warnings. 8-)
