Frequency response on amps?

[jay21112]

5hz is not audible. You have to consider what 15, 10, 5hz feel like.

...like a gust of wind going over your entire body. It's not "rumble". "rumble" is closer to 30hz - 50hz.

So, no, you won't "feel" it correctly. In fact with those devices, it'll be the same as 50hz. Just your *** being vibrated. I ain't into that sorta thing.

Interesting yet again.
I never thought about the fact that different hz are felt differently.

True that with these devices it will just be rumble though.

We'll see. My understanding is that once hooked up and calibrated to the system the mind and body work together to "hear" one signal instead of hearing and feeling different signals.

The transducer works in synch with the sub to fool the mind into hearing a more forceful (and louder) sound. The physics and biomechanics sound intriguing and amazing. There is no way I couldn't try this out and see for myself.

It's one hell of a long project though, so it'll be a while before I get results. I still have another month of production on my couch, and then I have to buy all the connects for the amps and mixer, install the transducers in the couch, run and hide all the wires, and calibrate it.
...it's a good thing I like doing all this or I'd mistake it for a lot of work.

The buttkicker will be an inaccurate reproduction of low-frequency sound, but if that doesn't mean you shouldn't use it and enjoy what it does.

A lot of gear is about -3dB or so a 5Hz. Receiver/pre-amp plus an amp means you'll be doubling that. And despite what people are saying, there is content that goes that low and if you want to feel it then you should try for that. My subs are flat to 5Hz in-room at reference level because I designed them for that. (And yes, the low stuff is either like a gust of wind or earthquake-ish rumble due to your house moving.) But you can also easily purchase subs that are relatively flat, at lower SPL which you can then double-up on, into the teens. But it won't be the same as the buttkicker.

I say first give the Crown amps a try and stop worrying about the specification to see if it gives you what you want. If you really want to find out, just give Crown a call and ask them about the frequency response below 20Hz. I'm sure someone will try to get you the right answer.

If you have a good system, I can't imagine why you need a device like this.

My wife and I watched War Horse last night and I can tell you our butts got more than a therapeutic massage and I don't even use subs!

I thought the audio engineering on this movie was absolutely superb. There was not one thing I would fault.

It put you right on the battle scenes, with the guns seeming to come from a long way off, bullets screaming over head and going way into the distance. It really felt exactly like being out on the open. We both lost track of the fact we were actually inside.

The dialog and sounds of the horses and everything recorded was spot on. The sound track was open and spacious with a huge sound stage. Instrumental sound was right up there with the very best orchestral recordings.

This movie now goes right to the top of the list for finest sound track. Totally blew us way and a wonderful movie as well.

I just can't imagine a butt kicker adding anything but distraction, any more rumbling on the backside would be a negative.

Another thing I noted about the technical excellence of this movie, was absolutely zero boom or bass bloom. A fantastic audio achievement, the excellent cinematography was added bonus. However it was the audio that placed you as actually being there I think.

This is yet another movie were all speakers need to be very good and powerful.

So I would not waste money on but kickers, but improving speakers.

With an all cement floor and cement 1/2 way up the walls (basement foundation), my entire house shakes long before my bum does.

That is resonance which concrete is prone to. The question is does you system produce shock waves that physically hit you hard in the chest.

I have absolutely no need for a butt kicker. If I handled my system carelessly I could easily push out the walls and windows.
