130 dB needs about 2 minutes to damage one's hearing, so yes, it's insanity.

Yeah...they're nuts. I wonder if the anechoic chamber will ignite as sound waves get converted to heat.

What most don't understand is 110 dB will drive you from the room, and 120 dB will cause hearing damage fairly quickly.

Then add into the mix the room gain, and a pair of speakers, and I cannot imagine a scenario in a home in which a pair of M100's would not be able to generate 115 dB at the listening position from 80 Hz and up.

Back to "driving you from the room" ... in our blind tests here, I have run a 90 dB sine wave (measured from the listening position) and asked people to guess the SPL. It was so loud the lowest guess was 100 dB. The average guess was 107-108 dB.

Does this help answer the question?


What I don't understand then Craig, is why there are talks of developing the T-Rex speaker that, anecdotally, is being conceived to deliver 130 dB anechoicaly. This sounds like insanity!


Whoa! Can someone shed more light on this rumour?

I enjoy overly loud and one of the reasons I'm planning on upgrading my m80s

When I bought my m80's....the m100 were officially released only a few weeks later.

I was GENEROUSLY offered a full refund from axiom to upgrade to the m100 (and thats when they were at a introductory price and much cheaper lol), but was going through a divorce and couldn't even fathom coming up with the 500 dollars or so. That, and I felt guilty. New products are always and will always be coming out. I missed out fair and square.

Well, I'm so in love with my m80s and almost regret not making it happen lol

They are much more money now, but they are definitely worth the money. A lot of great time, energy, money and engineering went into those and the performance is top notch.

So I'm saving. This Xmas I bought the qs10's. Next Xmas it's the m100's and an ep800 wink

With the trade in or sale of my m80 v3, my loyalty discount and waiting for a sale like the black Friday discount, I am going to have to come up with 4000 (on top of the trade in)

But....if there is a new badboy rolling into town by then..I NEED to knows!!!! Haha

I know what you are looking for; loud, clean, and dynamic. I am a big fan myself of this. I would suggest the addition of an ADA1500-3 http://www.axiomaudio.com/1500-amplifier amplifier to your system before changing the speakers.

Noted.

I was running a Rotel RMB-1095 power amplifier.

I lent it to a family member who lent it to a family member...came back to me with the left channels not working. It's not a fuse

I've been eying up your amplifiers since they were shown. And it's definitely on my menu

I'm very happy with my m80s. Best speaker I've ever owned.

Mad Chesser. I would look to toss the Pioneer if you want to up your sound. I have have been through quite a few of the Pioneer amps from the lower VSX-1126 to the SC-1227, SC-1528 and all of them no matter what I did, didn't produce the clean dynamic sound that I was expecting.

If I went back to old school Nakamichi AV1 the speakers came alive with dynamics, an incredible sound stage, pin accurate placement, and none of the wishy washy malaze that I seemed to get from the Pioneer.
Not to say it was just limited to Pioneer, but I found about the same level from Integra, Marantz as well. I put in countless hours trying to get the sound that I knew I could get. Moving speakers, adjusting the room finishes that I could. Then I gave in and threw my money good over bad into an Anthem and it was like lifting a veil back off the sound.

Amps like the ADA1500 can only produce a good sound if the source that they are getting is good and clean. I found that the Pioneer that I had didn't give that. I went from the M80 directly to the LFR1100 that isn't a forgiving speaker. it gives you back exactly what you feed it in amplitude. so if your system isn't up to snuff, then you miss out on great sound and hear all the flaws in your face.

I know the Pioneer isn't a cheap receiver. But I would hate for you to go down the same path that I was on trying to get better sound only to be hobbling yourself from getting it by replacing the wrong parts.

Axiom: ADA1500, LFR1100 Actiive, QS8, EP500, M3, M3comp, M5
