Hey guys,

I was looking at some deep bass movies at svssubwoofers.com site specifically the Star Wars 1 - Phantom Menace, http://www.svsubwoofers.com/faq_tpm.htm

It mentions there that some scene on the movie that does an extreme 10hz. I have a 20-39 PCi. Before, I downloaded the NCH Tone Generator and tried 20hz, 19hz, 18hz, and 17hz tones. Only on the 17hz that I didn't hear anything nor felt anything.

So my question is: Is it normal for my 20-39 PCi to not be able to produce that deep bass on the scene properly? If I recall correctly, in the tunnel explosion in the same movie, I heard like my sub was claking(sounds like clocking). Damn, I couldn't remember the term but I guess you know what I mean.

Thanks,

Neil

Ronneil, relax, how long have you had your SVS?

learn to accept and enjoy.

the clacking was your sub bottoming out. meaning that the FR it was trying to produce was most likeley below the port tuning point. meaning your sub cannot go that low.

"Only on the 17hz that I didn't hear anything nor felt anything."
meaning thats about as low as your sub can go and thats with a sine wave. true sounds do not follow the sine wave curve but have their own signature to it [just as a middle C on a piano sounds different than a middle C on a trumpet].
So were you will start to bottom out somewhat depends on the power required, the sound itself, and the design of your sub, not to mention room acoustics and whatnot.
I remember a few months ago, you were exctatic that your new SVS was LOUD and LOW, but now you are feeling it is lacking? relax. If you want to make sure you can get 10 HZ at ref, buy 8 B4+'s, and im not even sure that will do it. if upgraditis has bit you this soon after all your purchases, I want to be your HT equipment dealer .

Ronneil,

I agree with Charlie. It takes a fairly substantial sub to get even to 20Hz, especially if you have a large room. 10Hz, and at reference levels? Can you say “refrigerator?” That’s about the size your sub would have to be. (Come to think of it, isn't that about how big eight B4's would be? )

I've got a 16-46PCi, and I have a hard time hearing a 15Hz tone, but it definetely registers on the SPL meter. I think when things get down that low, they become pretty hard to hear (for most of us), although you may feel them.

so how do you tell the difference between sounds under 15hz?

The more nauseous you get, the lower the frequency. Seriously, ultra-low bass (under 16 or so Hz) is something you feel, not hear.

[Allen Marshall]

so if your subwoofer can pull off like 110db at 16hz or more, then nobody would or should care how it is lower cause you cant hear a difference anyway?

[PeterK]

I was just going to say that can't you not hear frequencies below 20. But i guess you can feel them?

[john michiels]

Did you try listening from different positions in your room?
You might be listening from a null position for that specific frequency.

Anyhow: Sounds like your system is pretty darn good....enjoy it and don't get too caught up trying to demo the unrealistic condition of a pure 17hz tone.

Please don't take this as obnoxious as it sounds but....Does the fact that you are incapable of seeing ultraviolet light upset you too? Hypothetically, would you upgrade an amp to improve performance from .0005 to.0001 THD if you could not hear the difference? Upgrading equipment (spending $) is fun but I think that you might be able to find room for improvement in another area of your system.

Enjoy

Aight guys, I'll just spend my money then on the Swan 2.1s and C3

Thanks for all your input. It really helps!

"so if your subwoofer can pull off like 110db at 16hz or more, then nobody would or should care how it is lower cause you cant hear a difference anyway? "

110 db's at 16 HZ, your house should be shaking so much that what you actually hear is either 1) your wife/gf screaming at you to turn it down 2) all the dishes/windows/things on shelves are rattling till they fall off 3) sirens cause your neighbors thought there is a lowrider out front 4) sirens cause your neighbors think there has been an earthquake

It upsets me. Hell, I also want Steve Austins bionic eye.

Bat ears would also be cool.
