I'm going to take my time deciding which model to get next, but it'll be something bass/mid centric.

I've been trying some online tone sweeps and the YH-TF10 seems to make sounds audible right down to 20 Hz, maybe even 18 depending on which generator I use.
The you-tube generators seem pretty useless though, some seem to suggest that sound is audible down to 4-5 Hz!, which can't be right at all.

 

There are frequency charts that suggest the TF10's are able to produce tones down to 10Hz. They may well be able to, but what they can't do is produce low bass with any impact, I don't think this is a particular limitation of the TF10's, pretty much most BA drivers struggle with low bass extension.

 

I, like you, have eclectic musical tastes and I was looking for the TF10 with the added dynamic to be able to produce the bass extension AND impact that some modern forms of music require. Hopefully, what you have got with your added dynamic now, is both the bass extension and the actual impact that goes with that extension. Certainly the dynamic should be able to do that far better than the BA could.

I guess at this point I will just take a bit more time and see more impressions on the BA4 since I can't seem to get a reply from Phil. Guess I will just spend my money on tuning my car first!

That is indeed rich, since humans cannot hear below 20 hz :D

No, you're wrong. There are also humans who can hear the difference in HD audio recordings compared to CD, despite blind tests proving they can't. biggrin.gif

Yeah, you're right :D

 

Had a big discussion with my to be father in law, he said flac was way way better than mp3s, also 320kbps. I asked him if he ever compared the same song, on the same system on mp3 vs flac. He didn't. 

I then downloaded an album for him that he wanted in flac, but also put in some mp3 songs in that playlist. He loved them all :p

He said you can easily hear the difference in soundstage in flac and mp3 files, his evidence: he had a song in mp3 with little stereo effects. Producing quality is way more important than the actual bitrate imo. 

 

That's a thing I genuinely hate amongst amateur audiophiles, bragging about things, without even knowing basic concepts such as a frequency response. Stuff like: "my subwoofer goes down to 2 hz" - maybe, but at like minus 40db - "What?".

There is a theory that even though we can't actually "hear" frequencies below 20hz and above 20khz (i.e. perceive them as actual sound) we can still "feel" them, and since they are produced in a live setting, having those frequencies produced by headphones/speakers will make you feel more like you're listening to a live instrument. I've never owned supersonic gear so I have no idea what they're talking about, but hey, they might have a point.

All I end up hearing around and below 20hz is harmonic distortion on the majority of setups I've heard. I honestly don't need it to go THAT low in order to enjoy music.

True, however, no 'normal' stereo setup will actually go that low. Just like I said, it might reach 5hz, but it certainly will not be a linear response. If anything is felt below 20hz, it's probably just harmonic distortion.

I have headphones that go below 20hz and there's not really much of a sound, but there is a lot of driver movement, and the bass massage is awesome.

Planar?

No, they were the M-Audio Q40s with an amp. I thought I might have been imagining it, or something, but MalVeauX reported audible and strong sound under 15hz (http://www.head-fi.org/products/m-audio-studiophile-q40-closed-back-dynamic-headphones/reviews/6430)

Heres the quote

"In Audiacity, I tested 10hz and I could hear it, it was dim, but I could hear it. 15hz was definitely audible, but had a wobble to it. 20hz hit with authority, a slight wobble to it, but very prominent. So this headphone drops to 20hz before it really falls off. It can do serious sub-bass. Naturally, most music is not this low. 30hz was serious. Very satisfying and rich. Put to the test on real music, it was very authoritative and impactful with some dance music, trance, dub and the like. The slam was great, the drops were serious, they were gut busting. This is defintiely a basshead worth headphone. The bass is not muddy and cruddy though. It's not perfectly tight, but it's not a loose cannon either. The mid-bass is a touch more than the sub-bass, but not in a way that kills the mids (which is why the mids are preserved probably). Without amplification, it drops this low, but I feel it is a little better and decay is better and recovery is better with a little amplification behind it, but this is my subjective opinion on that."

 

I imagine that in ears probably, especially customs will seal better than full size headphones. So I think it is possible that the TF-10 hybrids reach 10hz, but I'm not sure how loud or audible it would be.

Maybe he has super ears. I'm betting it was harmonic distortion he heard and not an actual tone. But you never know.

Has anyone heard anything abaut the new BA5?

When wil they go out for sale, have anyone been allowed to try a set?

post #2385 of 4267

For guys that have ordered BA4s, do you guys know about when you'll be getting yours? I got a response from Phil and he says that if I send in my impressions soon, he can get started on the BA4s at the end of August and take about 2-3 weeks.
