Axiom Home Page Forums General Discussion Stereo Crossover setting for new M80s

I guess I'll have to play around with it. I am also getting the new Yamaha RX-V2600 so I'll have to dial that in too. It does have an adjustable crossover as opposed to my Onkyo which is fixed. I am not sure where it is fixed at though. I prefer the sound in pure direct sending full range to the M80's. It just seems something is missing when using the sub on this receiver. The EP500 may change things though as may being able to set the crossover lower. Experimenting is all part of the fun though.

Let us know how things turn out!

Don't know if you would be interested in the THX settings, but my Onkyo specifieds the THX as 80 Hz. That is were I set my speakers.

Could you make a speaker with all the drivers of an M60 or M80, put it in a smaller box and sacrifice some bass extension, and still get as good a sound in an HT system ? Probably, but nobody would buy it

Sounds like a great new center channel!!!

When watching THX movies I set the crossover at 80Hz. But when I am listening to music, I set the crossover at 40Hz. The M80s can go down to 34Hz. I have tried out 40, 60 and 80Hz settings. The overall audio experience is somewhat different depending on the source. I think you can just leave it at 80hz for both movies and music. But it seems a shame to do it for almost full range speakers like the M80s! These days I am using the 40Hz setting.

The other issue with my Denon AVR is whether to set the speakers to Large or Small. I am using the Large setting for all my speakers now. But again, depending on your sound preferences, you may like a different setting! Experiment and enjoy!

I have been an Axiom owner for only a few months. I have been trying out the speakers with different settings and various types of audio and video material. The 4ohm M80s do like a powerful amplifier!

I'd say a cross over of 80Hz would work well with the M80v2.

As to the graph posted for the M80s, it does appear the 80s start to fall off at around 80Hz. As Ian has stated a few times, as well as others, the NCR chamber is accurate to only 85Hz. The graph does not take into account in room response.

From Soundstage

"One should recognize that since these measurements are performed in anechoic chamber, they will generally show less bass than what you can expect in a real room."

From the Soundstage review. "I’d estimate bass to a solid 30 or 35Hz in my room"

So it would be OK to set the crossover at 40Hz and enjoy the full range of sound from the M80s.

I think an 80Hz cross over point with a 6 db slope would be perfect.
