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

Hello Ray3,

Hope you are well. You got me thinking. So, I have just looked through my CD collection and I have one CD with music played on the Sydney Town Hall Organ. This organ is one of only 2 in the world with a 64 foot tall C-1 note reed, that translates to 8.18Hz. Obviously with my current equipment I have never felt that note before, and probably never will with the full impact without visiting Sydney for a concert...hehe. Another instrument that goes pretty deep is an Imperial Grand Piano, lowest note is C0, or 16.35Hz, this is also the lowest note for a Tuba. Moving up from there the lowest bass guitar strings are C#0, at 17.32Hz. That last one probably plays fine on the 20-39Pci.

I will probably try that 12Hz tuning point and see what 8Hz feels like, at least I will never feel like I am missing the low end.

Thank You for getting me thinking, and truely evaluating my decision.

Sounds like my simple suggestion was a bit short of the thought process you already went through . I love it when choices are supported by research and thinking. Makes the end result that much sweeter. I am sure you will love the 16-46. You also phrased it correctly - at those levels you tend to stop hearing and start feeling the LFE. If this is your first quality sub, you are in for a treat.

Hello Ray3,

Hope you are well. There was nothing simple about your suggestion, it made me re-evaluate my decision, which is a good thing. I went back and really looked at the frequency charts to see if I really needed the 16-46PC Plus vs the 20-39PC Plus version. Even though there is only a $50 difference in cost between the two versions.

I also looked at the PCi variant that you have, but it does not have the variable tuning capability and the variable subsonic filters that the newer PC Plus ones have. The frequency response of the newer aluminum driver in the PC Plus versions was much more linear also.

As most of you know my TV blew on me so I have been bored today. I have been playing with the the 2 M3's as a center. Currently my Denon was doing it at 4ohms. I took my Acurus A125X5 and ran a cable from my the pre-out for the center from my Denon and stuck a Y in there and hooked up each M3 to it's own channel on the Acurus. I LIKE IT!!!!!! Little more punch then what I had before. Takes a load off the Denon to.

Hello NeverHappy,

Hope you are well. Yeah, running a 4oHm load like we are is very demanding. I have been looking at the Outlaw 755 200wpc X 5, it has 5 discrete amplifiers and puts out 200wpc at 8oHms and 300wpc into 4oHms. Gonna have to wait a bit though it is $1,299, I may be able to talk my Wife into the M200 mono block for the center it is the same 300watts into a 4oHm load and only $299 plus shipping.

Glad to see your M3 experiment is still producing good results, I have seen no downside yet to using my two M2s as my center channel.

How about a pic, Tony? I'd love to see how they look on top of a TV.

Helle BigWill,

Hope you are well. I am sorry, I don't own a digital camera, I am kind of a dinosaur..hehe. My Wife says they are 'cute', so they must not look that bad up there, eh? That is like a 10+ on the WAF scale, no?

This thread has got me thinking seriously about using 2 M2's in my system. I'm currently using 1 vertical M2. I need a little technical advice. I'm running a HK AVR 130 (55 watts/channel @ 8 ohms in stereo, 45 watt/channel in 5.1. What are the implications for this receiver when running 2 M2's at 4 ohms. Is it feasible? A bigger receiver is in my future plans, but not immediately. Thanks.

Hello Jorge016,

Hope you are well. Harman/Kardon receivers have a lot of current, but yours seems a little small to try 2 M2s on one channel. Does the AVR 130 have pre amp outputs to add on a beefier center channel amplifier? Your smaller receiver may overheat, or worse clip the signal causing damage to your speakers.

The AVR 630 that I have is rated at 75 watt/channel into 7 channels 20Hz to 20kHz, and 90 watt/channel in stereo 20Hz to 20kHz. So, that is 30 more available watts in surround mode.

Personally I don't think it is worth the risk of damage to your system.

You confirmed my suspicions, Tony. No preamps on the 130. I'll wait until upgraditis overtakes me. I appreciate the help.
