Axiom Home Page Forums General Discussion Technical Questions question for the pro's on M80's or M22's

Ok
my current setup is all small in my reciever with LFE+Mains. It is cut off at 80 hz
Now, if I set it to large as I have the M80's and the rest small as they are VP150 and qs8's, I still get base below 80hz actually all of it to the mains still because LFE+MAins.
But, the M80's are good to 35hz, so they will play 35hz and try to do the rest say 25 hz if it is load then they will distort....basically. So, therefore I don't want that so I go back and set all speakers to small ( which I have read numerous articles on ) and then that gives me LFE and all LF below 80 hz goes to the sub. Correct ?

Why then did I buy the Mt80's if I will not use the full speaker ,why should we not settle for Mt22 at a 1/3rd of the cost ?
not that I will change I love my 80's, but just curious

They don't distort, they just roll off. Simple physics--6 1/2" drivers can't go that low and produce much output.

When set to 80hz, it does not "cut off", as Ken mentioned there is a slope or pass-off to the sub. 80 hz is very low, most music never touches 80hz. Below 80hz, the sound starts to become non-directional and the sub is best suited to move more air.

The 80's actually do very well down into the lower frequencies if your receiver allows you to set a seperate crossover for them, try 60hz for music.

What works great for me is setting the cut-off to 80 for movies and 40 for music. I have mine set to LFE.

You bought the M80s because they are more sensitive, can play more than 4 times as loud, look more impressive and have better imaging .

Hi axiom_man,

As others have explained in this thread, when you set the M80s to "Small" and use a crossover frequency of 80 Hz or 60 Hz, it's a very gradual transition from the lower bass octaves to the subwoofer.

If you go up to the M80s when they are set to Small and play music with bass content, lightly touch the M80s woofers and you'll find that they are still producing bass output. But they don't have to "work" nearly as hard--the back-and-forth excursion of the woofer cones is much less--as the subwoofer takes up the slack and does all the bass heavy lifting, so to speak.

Set to Small, I find that the M80s used with a sub still have more lower bass "authority" than do the M22s used with a sub. I have both on a comparator in my living room and use 80 Hz as the crossover frequency when I make the comparisons.

Regards,

Just want to be clear--the M80s don't distort below 35Hz. That's the rolloff I was talking about. The output just drops (gradually). The rolloff other people are talking about, from the crossover, also occurs.

So, which is the perferred settings ... MT80's set to small or large and what is the recievers crossover set at ?
maybe I should have a poll

Set the M80s to small and use a cross-over of 80 Hz for movies and 40 Hz for music. Start with that and fiddle from there if you have to.

I just have mine set to 40 Hz for video, large for music, with a 40 Hz cross there as well for the sub. Of course, I have an H/K, so I get to set different crosses for different channels.

Mine are set to 60Hz on my ICBM, no setting for large or small.
