asgb is a bass monitor single dynamic driver afaik
The 2.0 v.s. the 2.5 is a shift in the bass slope more towards the sub-bass. Not sure if one is more. The bass tests we did with over ear showed most of the head vibe coming from 30-55Hz and the punch around 55-70Hz. Beyond that is more heard than felt. Skullcandy...god bless their
neat idea soul....calls the driver in the crushers or that vibe generating set the 55____...not because it's 55mm, it's 40 but because they determined the 55Hz freq to be the the sweet point that loosens the ear wax. We came to the same conclusion or a tad lower with over ear.
IEM cannot be compared like that but my 15inch subs were crossed over at 53,55,58 Hz 90% of the time and in over ear it was the sweet spot and IEM seem to be no different. I did a demo vid with the IEM on the mic while I switched from genre to genre and the took everything like a champ but youtube put like 5 copyright claims on it because of the music in the background so it's unviewable in 5+ countries.
The 2.5 need zero help via eq or hardware boost. I leave my cayin C5 bass switch on by default and switch gain sometimes and eq on the X5 but the issue i thought existed at 300Hz was solved by going high gain on the C5 and switching the bass boost off
That made no sense. IEM can eat a Cayin high gain? Yup. The bass boost would distort some 40mm over ear but it just bloated the IEM. Turn that off and stay high gain and flat eq and it slams. No more 300Hz issue.
The quotes below are from around 30 seconds in and their is a bass heartbeat dominating the track at this point. The first spoken word sentence is mixed in a couple dB lower than the second but it should be clear and it is about 300Hz. It's a frequency rally point. You make adjusts off it.
The album was mixed at Abbey Road studios by Alan Parsons.
“I've been mad for ******* years, absolutely years. I've been over the edge for yonks. Been working with bands so long, I think. Crikey...”
“I've always been mad, I know I've been mad, like the most of us are. It's very hard to explain why you're mad, even if you're not mad.”
That first spoken word was dull..... I was livid. My Sony A2 3 way sound better and they cost 300...What? Turns out it was too low a gain and the bass boost was not needed. Very counter intuitive for a basshead and IEM noob. I could not imagine they want more power and need no assistance aside from it's own tuning dial.
The 2.5 were said to be harder to drive and they must be because the Sony cannot take the high gain without getting shouty and sounding not healthy. The ASG want your power.
A very impressive piece of work by the folks at Aursonics.
The soundstage is epic and crushes the Sony...I mean it's like going from surround sound to an alarm clock radio when "A" "B" ing.
