Axiom Home Page Forums General Discussion Technical Questions Understanding Graphs, roll off and M100 querys

Maybe should split these upinto different posts but i'll see how this goes...

First thing, looking into the m100 specs, the standard tower specs vs the wireless version with built in amps, shows not identical specs. Im wondering why this is?

IE: the weights are different...ok fine, one has amps on board the other doesnt. No problem, makes sense.

But the sensitivity are one db difference. Not a big deal, could be affected by cabinet internal volume perhaps with amps versus no maps inside.

But the crossovers show a 40 hz difference in the mid to low range exchange, and the mid to high frequencies show a 0.3hz differnece at hat handoff. Just a typo in the spec sheet? Or is there actually a slightly tweeked crossover between the 2? Or is it the wireless version v4 specs and the m100 tower spec sheet is an older version and juist not updated? I'm kinda doubting the crossovers are sold different as I know Axiom is stalwart in their quality control within there " reference " modeling they use to keep continuity within the brand, IE not using " matched pairs" to ship out or worriying about sequential serial numbers etc.

I'll ask my roll off question in a bit as I continue my m100 research.

Very good. Look at you go! It's quite possible the cross-overs are different to account for the different volume due to the amp. The frequency response curve can't be correct either.

Ok good. I’m not crazy then. But a 40hz crossover step seems like a lot.

The only reason I noticed is I was exploring maybe the wireless m100. No wires seems nice but I’m not convinced. Plus those are way less likely to come up on b stock etc.

As for the the graphs the bass roll off doesn’t look like what I’ve heard described by owners of m100. It seems to start a soft roll off quite high versus the deep bass that this tower is touted as having. But I will admit I don’t exactly correlate well with understanding roll off and db loss versus octave in the real world. Looks like 30 hz is achieved but but 10 db or so from roll off starting point.

As for the cross-overs, it's quite possible they reflect a new production version of the family of curves. For all we know, that new version may be in the wired M100s too and the specs are wrong for that model.

The bass blooms in room so bass down to 30Hz or lower is possible.

Yeah. I bet that’s the case. The wired version probably just needs an updated spec page. My hope is that the m100 can produce the bass and emotion I want in room with out subs.

My room is very large but where does one stop measuring cubic volume? If I include EVERYTHING that is attached in terms of open space than it’s very big. But if I include just the “ immediate “volume it’s just plain big but not insane.

Everything that is coupled to the airspace.

Define coupled…?

Does a closed door “ decouple “ ( to use the term loosely )

What about the standard stairwell to the upstairs? It’s a contained stairway but rises 18-19 feet to upper ceiling.

Thankyou!

Define "door".

Standard interior door that connects main living space to a 600-700 cubed mud room.

So basically a hole.
