Axiom Home Page Forums General Discussion Stereo Axiom M100 vs. Bryston Model T

They put the speaker on a pedestal with a mic 2 meters away inside the chamber. They measure the amplitude response. They spin the speaker 7.5 degrees and again measure the response. They keep doing this until they've spun the speaker 360 degrees. Then they lay it down flat and repeat all over again. They end up with two sets of measurements. These sets are called The Family of Curves.

The set of curves +/- 30 degrees with the speaker standing up is called the Listening Window. It's called that because listeners are typically seated within that 30 degree arc. The averaged response of all measurements is called the Sound Power. This represents the acoustic intensity (flux) that intersects the surface of an imaginary sphere around the speaker. Both curves are plotted as SPL vs. Frequency.

When the Listening Window and Sound Power curves ride on top of each other, and decline at roughly 3dB per decade of frequency, magic happens. Speakers and room disappear and all you're left with is the performance. That's active LFR magic.

For sure Axiom has target curves of their own recipe. I know this because I've heard most of the v4 in my own home...and their tone, imaging and soundstage sound similar no matter what their price. This is quite an amazing thing! You don't get poor acoustic quality with smaller, cheaper models.

Hey McBlue, what tipped the balance toward getting the Brystons over the Axioms? Zero judgemnt here at all, as i haven't heard either the Model T Passive or the M100 speakers. Were you able to demo either of them somehow before commiting? That can be areal challenge most times to demo them.

I really like the appearance of the Model T. Super stout and classy looking.

I just read a great review on the Bryston Middle T Active. It was from awhile ago....2018.

I got to thinking it would my awesome to see an Axiom LFR 660 and 880 Active system with HP for smaller spaces and slightly lower buy in price. That would be cool.....

For that matter, I wonder if an M5HP could be DSP'd and seperated amplification and sound even more amazing?! Or all the M series offered up with external DSP and 3 channel apmplification?

Random ideas from me in daydream mode.......im sure im not the first to have these ideas!

Hey Kodiak
His book is titled “Sound Reproduction” The Acoustics and Psychoacoustics of Loudspeakers and Rooms. Third Edition. It is, in my opinion technical. But readable. But, rather than spend $50+ for a copy maybe watching Floyd Tooles video on this could be a reasonable alternative?
Floyd Toole Sound Reproduction -Art-Science/Opinions and Facts. Just a forewarning, it is long.
Cheers,

Axiom is planning an active M5HP which means the M5 will be made more linear than its passive sister. The M2 however is so linear it doesn't practically benefit from a DSP except perhaps to be made more sensitive (louder).

Nope. Every piece of electronics in the current line was designed and built in house. By me...at least the design part.

Andrew, that's quite impressive. Did you lay out the PCBs for all the electronics?

Yessir!

My man! Good for you!!

Hi Andrew!

I sure enjoy your LFR1100s with the ADA1500 amps. Curious about the D amp module. Is it based on an ICE, Hypex, Ncore ... ?
