Axiom Home Page Forums General Discussion Advice from Axiom Owners New M2is, Using 2 as center channel.

Hello NeverHappy,

Hope you are well (or happy?). Yes, the VP100 is +/-3db 95Hz-22kHz and the VP150 is +/-3db 85Hz-22kHz. The M2i is +/-3db 70Hz-20kHz, so an easy 80Hz crossover.

Also think of using 2 M2i together as the top half of one M80ti, you have two 5.25" and two 1" titanium tweeters at 4Ohms load. Power handling in parallel is additive so each M2i is 150 watts max powerhandling, times two is 300 watts max for the set.

I am still amazed at how smooth they are in the transition to the sub, and the clarity of sound in general. These are good speakers.

I have moved them again to try out as mains, and noticed that different CDs can be much louder at a given volume level than others. My first measurements were only with an old Simon and Garfunkel CD, had to crank the volume, but the newer CDs are better at between -25 and -30 volume I was registering C weighted SPLs of 62 to 74 at -30, and 65 to 81 at -25. These were taken with some Handel and Bach Baroque orchestral music, lots of dynamic range there.

This really makes me want a pair of M22Ti badly, hehe.

So then I guess my nest question is with my crossover set at 80, I'm actually losing audio from my VP100? I have a set of M3TI's in the back. Maybe I should use one as a center?????

Hello NeverHappy,

Hope you are well. Your frequency range below 95Hz is not in your +/-3db range of the VP100. I would switch to a 100Hz crossover with your setup. Frequencies below 95Hz will drop in db depending on how quickly the VP100 trails off in the low end. You will still get sound down to about 65Hz, but it will not be as loud as what you get from 95Hz on up. Would be nice to see a graph of the frequency response of the VP100 and VP150, but I have not been able to find one.

Here is the frequency response chart for the M2i from the Soundstage review.

and here is the one for the M3Ti that you own.

both cross over at 80Hz perfectly.

As to using one M3Ti, I tried one M2i and found it limited by itself, adding the second M2i disperses the center channel much better than one. I am quite happy with what I am hearing.

You could try doing a frequency sweep on the center channel and see where the dropoff is.

This is interesting, esp since I have yet pushed the *buy now* button. And M2's would be ~100 bux cheaper than the VP150.

hmmmmmmmmmmmmmmmmmm

Hello INANE,

Hope you are well. If you are thinking on trying this setup out, make sure your amp or receiver can handle a 4 oHm load.

Tony you win the award for being the most polite on the forums, hope you are well yourself.

As far as the AVR, I happen to have a HK 630 myself!

Hello INANE,

Thank you for the complement. I love my AVR 630, how do you like yours? HK really underrates it when they say it is 75 watts per channel, those high current watts are quite impressive. I listen to a lot of classical, and it handles insane dynamic range with ease.

TonyM, thank you for the information. I'm fairly sure my 3805 can handle the 4ohm load. If not I have other amps that will do the job. I'm going to give this a try and run a set of M3's and see what happens. I have 50's up front and I think the M3's will work better with them verus the M2's.

I'll be interested in the results.. You don't have a pair of M2s as well, do you? It would be interesting to see a comparison of the two in regards to the M50s.
