[REVIEW] Aurisonics ASG-2 & 2.5 (with many comparisons)
Aug 28, 2013 at 2:41 PM Post #3,271 of 7,021
Just too clear up any possible confusion on my impressions-

I found them both to be pretty equally loud at 20hz but the ASG-2 was louder at 150hz. This is why I speculated that perhaps the bass dial had been torqued too far on the measured pair. 20hz was loud in my test tone app. Over torquing the bass vents would cause it to lose deep bass and become mismatched. Any louder at 20hz and you are entering MG6pro territory. The rest of my testing and impressions pretty much agree with the measurements over 150hz.

FYI- The overwhelming majority of the music I listen to has its content between 40hz and 13k, containing 40hz quite often.

(y) I'll chime in with a few $ for shipping if you dedicate your ASG-2's time for that.

Cheers, but no need. It's only a few dollars CONUS via USPS. I'm broke, but not that broke.

Just like everyone has been saying, the emphasis goes on the mid-bass but the sub-bass is very much there.

Carlsan, i will be curious to read your comparisons between two :)

Right now i am listening to Joe Dassin in flac 24/192, lovely good old times and music.

Eke, rather contrary to my ear, mid bass is very well defined on ASG but sub bass is missing a bit, there is big impact but lack of fine detail. i can easily tell this if put Yello's song Out of Dawn on my front end system, which does bass nicely down to 27hz at peaks.

Yup.

I was just running the F111 through a sine tone generator and it's pretty darn linear down to pretty much 40hz, then starts to roll off and to my ears is entirely inaudible nor can it be felt by 20hz. The problem is that there's just no weight to hold up the subbass with the graphically minimal roll off on the F111. The G-2 on the other hand has significant weight behind the entire lower frequency range and even with the visual roll off is clearly felt at the very least, even below 20hz.

Clearly, I only speak for my G-2. And I bring up the F111 as its been related to the ER4 which was brought up earlier. My music often goes down to 40hz also fwiw.

Seems to me that iem measurements would be somewhat like speaker measurements, where the ear canal would be the analog of 'the room'.  That said, if tips insertion angle, insertion depth (room effects, in other words) along with the specifics a a particular person's ear canal, all effect the sound - not to mention the driving amp, and the measuring device - how much stock should we place in any of these measurements?  Additionally, why the emphasis on amplitude without any attention to time-domain performance?  
 
 
This would be like buying speakers based on measurements made in someone else's room -- how much can this really help us 'know' what the speaker (iem) really sounds like?
 
not trolling - i am curious to know how people view these measurements....

Vwinter, when sub bass drops below 30hz you still must be able to pick details and bass sensations, i rarely heard IEMs being capable of this.

in my book ASG does pretty good job down to 40hz, an Ok job down to 35hz but then sharp fallout, i hear rather voluminous noise than bass.

For grasping what low bass is about i always listen to pipe organ at church and it really shows me what bass means.

No doubt there's lot of music with content at 40Hz. Looking at the interactive frequency chart it seems the instruments that go that low are the tuba, bassoon, the lowest notes on a bass guitar, the harp, pipe organ, and about the bottom octave of the piano. Would you guys agree with that? Electronic music I'd say can have some audible bass at 40Hz. I'll do more listening though with rock music and see what adjusting 40Hz eq does for it. In my experience so far though it doesn't do much unless it starts to affect 50Hz and 60Hz. I'm expecting though that anything acoustic or without the lowest bass or piano notes won't really be affected by 40Hz. EQ for 60Hz is much much more audible in most cases to me.

Most of my electronic music goes down to having "fundamentals" at 40hz. Even if fundamental generated bass notes center around say 50hz, they often are rounded out by surrounding frequency "harmonics," above and below as much as 20-30hz in both directions. Take a look at some tracks in a decent spectrum visualizer.

@Gintaras
Better some than none lol. The oscillations are so wide and slow at 20hz that there's little detail to be had IMO, so it's more about the feeling. You can't compare to a church organ lol. the 1p2 does better in this regard though, just in case you were going there lol.

Purchased mine from Musicaacoustics.  They were sold out in from Ortofon USA.  Medium Ortofons have worked out well for me.  I have the Radioshack Auvio as well but haven't tried them yet.  Stock tips weren't that bad either.  Best isolation came from the Comply TS-500 but not the most comfortable for my ears.

I like the Auvio tips for comfort and sound. They're also a lot cheaper than the ortofons. You can get them at radio shack.

Question about the upcoming mods, especially the one for increasing subbass. Will these be upgradable for owners of asg-2, or is it a complete overhaul and be a seperate purchase

AFAIK, it should be similar to the ASG-1.0/1 to ASG-1.2 upgrade process. It's still too early though.
