SVS PC ultra has SERIOUS bass

[ay221]

I just got to try this out a few days ago. Now I configured it for 10 hz and played Nelly Furtado's "Childhood Dreams". It's late at night and I don't want to disturb the neighbors even though I live in a house.

I cranked up the sub, and played that song, and I could feel the waves of bass, the sub was shaking, and a poster tube holder that was on a table upstairs fell down. I will listen to the rest of the song tomorrow.

a lot of bass is one thing, but there 'can' be TOO MUCH...... but whatever floats your boat.

TOO MUCH is just right!

and you are the one who does not appreciate "real" bass. to hear or feel a 10hz note is nothing less than stellar. it is not volum but quality.

Although I haven't listened to the sub you have, I'm fairly confident my subwoofer is capable of going lower/louder without distorting..... but if you enjoy it... fine.

what is your sub again? that gives you "real" bass?

SVS, some of the sickest subs around!

I believe every bit of it! I watched Hitman the other day and it has some pretty intense and DEEP sound output in the 0.1 channel. I don't have the Ultra, but I have the 20-39 PC+ and there is a picture on the wall about 3ft. from it. It was actually bouncing off the wall(not just rattling) for a while and then it completely hopped off of the nail in the wall! It fell into a blanket so it didnt break so it really made my day!

I don't even have the gain turned up very loud, it is just so deep. It doesn't overpower the rest of my system but it does move alot of air and produce some very deep bass. I am completely satisfied with the PC+, I can only immagine what the Ultra can do.

By the way, if you want another house-shaking demo besides Hitman, try the beginning of Sweeny Todd. There is some very evil and EXTREMELY deep organ music there. Enjoy

just for fun (because I don't typically have the house to myself with a 5-6 month-old and wife, and also because I think it sounds terrible.....) I decided to see how low my sub could go, and not distort.....

WELL.... I didn't find a "Bottom" to which it would begin to break up..... I really pushed it, and turned off the center/surrounds, and was at the point where I didn't want to push my fronts any-more than I was too..... (B&W 703s)

My sub (14" Def Tech reference series) wouldn't distort at all.... but of course everything in my house was shaking, and I continuously had to turn it down.... take glass figurines/plates from the china cabinet, pictures, etc... and move them so they wouldn't fall/break etc!

My CD of choice was Les Claypool's Fearless Flying Frog Brigade's live performance of Pink Floyd's "Animals" but I listened to many other "Bass-Heavy" albums on CD/SACD as well.

My wife wanted to know why lamps etc were in the other room when she got home!!!!!

The only sub I use is a Rythmik DS12 based kit that I built myself, so I'm definitely into quality rather than quantity, but I don't even get to use THAT very much . I think I would wake up the little darlings if I did. Very frustrating.

I was strongly considering the Ultra when I was shopping since I had seen several people on various forums using dual Ultras. Now that I have the PC+, two Ultras is just ridiculous. I can understand needing one for a large room or whatever, but two is just insane. That is the guy that is waking you up at night!

To hear a 10hz note would be stellar - impossible, but stellar! I would actually be surprised if you could feel it that low - unless there is a whole lot of SPL behind that 10hz.

And outside of test tones, how much media actually contains frequencies that low?

not sure about "THAT" low, but I find most "bass-demo" SACDs to be Classical Music..... a LOT of low tones in Cello, etc.

While I am certainly not a expert in classical music, I would imagine the Cellos would be playing notes that could actually be heard - which would put it in at least the 20hz range.

Pipe organs can go down to 12Hz. And you must not have ever heard an SVS! I'm not sure about 10Hz, but I know they can hit 12 in the proper configuration. While you won't hear it that low, you will certainly feel it.

There aren't too many dvd's or BD's with frequencies that low. And classical music is what has the most data recorded in frequencies that low. However, there are plenty of BD's with strong activity at or below 20 Hz so it is definitely not a waste to get a good subwoofer.

I realize the need for a good sub, I am just questioning the 10hz claim. A just because a sub can go down to 10 or 12 hz does not mean it can't be felt, especially heard.

I know, what I'm telling you is that an SVS ultra will hit it(12Hz) with enough authority that you will certainly feel it. You probably won't hear it though.

that def tech supercube reference is.....AMAZING!

I had the chance to demo it a few months backs, and wow. that thing pounds. It was, however, in a showroom, so we couldnt really push it so far as to get the walls shaking because there were quite a few other people in the store, but still. haha. it was amazing.

The only time you're able to hear anything in the 20hz range and 20khz range is when you're a new born baby. the high and low end spectrum of your hearing has since been VERY degraded. so i'd be really impressed if any of you could still hear below 30hz.

Everything below that, you're gonna be feeling it. The length of a 20hz, or even 10hz sound wave is long, you're really only gonna be able to feel it, right in your chest. If you guys found a home theatre sub that you can actually feel.....then, well, job well done. Becuase the only time I've really been able to feel wave after wave hit me was from a pair of dual 18" subs running at 1200watts rms each at a small local all ages music venue that i owned.

Yeah, despite all the wall shaking etc.... I couldn't feel "wave after wave" but if I lightly clenched (clench isn't a good word) my teeth, they'd rattle!!! pretty fun!!! but like I said, If most people here heard my system, they'd think I have the sub way too low, but I try to make my system SOUND GOOD, not shake/vibrate stuff..... if you're just trying to feel the bass, get a butt-kicker installed, I myself prefer to use bass to fill the room at appropriate times, and not sound like a car-wreck when someone sets down a glass, or shuts a door.

I'm gonna watch U-571 when I go home...... it's deep, low bass sustained for a long time..... It's great!


EDIT.... also, funny you mention that, I see you have a ML sub.... I'm thinking about getting one, and getting rid of the Def-Tech. I am having a hard time setting it up, and I really think it's a little over-kill for my system. The Abyss in the downward firing configuration (or even the Dynamo) suits my needs better (and would free up cash for an amp upgrade) I've auditioned both, and the Dynamo I got to audition in my home.
