First, I would like to mention I don't know very much about AV's and speakers.

I recieved the speakers a few days ago M80 and VP150. Wondering
if my receive is adequate for the M80 and also is there a burn in period for the M80. Just not 100% convinced with them as of yet.
I have a Nad T765HD

regards,

Gerry

Hi Gerry, there is no "burn in" period for your(or any) speaker, more of a burn in period for your ears so to speak. Your T765 NAD should easily power the M80s according to NAD's specs.

Hello groy67 and welcome.

There is no burn in period for the M80's. Nad makes some nice gear, as long as the amp is not shutting down/going into protect mode it should be just fine.

What you might be experiencing is that the M80's sound different than any other speaker you have owned before. Spend some days doing extensive listening, and see if you get accustomed to their sound.

Hmmm.. I was instantly happy with my m80's.

What speakers did you primarily listen to before you purchased the m80's?

What type of music do you typically listen to?

Are you using any EQ or room correction software such as Audyssey?

How far are your speakers apart from each other, how far are they from the back wall, and how far are you from them?

How do you have them wired up?

Hi guys, Great forum!

I guess I'll answer a few question that you have asked.
a)My mains are approx 8' apart.
b)The music I like varies; Enigma, Eric Clapton, Sarah Brightman.
Mostly, I love watching movies.(Braveheart, Patriot, Troy etc...
c)I have Canton 507 Chrono series that I was using for the fronts but now I'm using them for the rears. They are only 3 weeks old.
d) I only used the auddesey funtion to calabrite my speakers.
e) the set up I used for the speakers are as follows;front main (large) centre (small) rears small and I have 2 subwoofers.
f) and my Av did clip once but I was little too anxious to try it at a high volume. My Nad has a soft clip funtion; what ever that means.
g)I'm using 12awg wire and BIAmped
Thanks for all your help. It's much appreciated!

If audyssey turned on any Room EQ features try turning them off (so that no EQ is Applied) and see how that sounds. I found that the audyssey EQ made my speakers sound worse. Many people have good results but I tried 3 times with mixed results at best.

You will want to change your fronts to small and use a crossover of about 60 or 80 hz more than likely.

Since the M80's are rear ported you can really change how they sound by moving them closer or farther from the back wall. Generally speaking, moving them closer to the wall will add a little emphasis on the bass. Is your music collection in lossy (mp3) or lossless (flac, wav or CD) format?

What subwoofers do you have?

I am not sure what "soft clipping means"... I have never had my receiver shut down once with the m80's (using denon 3808) And I have played it PLENTY loud. Did your receiver shut down on you when you say it clipped or what happened?

How do the Cantons differ from the Axioms sound wise? Make sure you do as noted above by David. That will ease up on the receiver. I would also forget the bi-amping too. Less of a load for the amp to drive.

I'm using Mp3 & Mp4 mostly with a C-200 Popcorn Hour media player HDMI output.
And yes when it clipped the Av did shut down.
The Canton's sounded brighter and cleaner and never clipped my AV before. lol but I am some how convinced the Axiom are better.
I'm using 2 PSB 10" subs.

So you're saying for the fronts to have the cross over at 60 to 80 hz?
hmm I'm surprised about biamping; because the "guy" from the audio place said; "it's always the best way of doing it".

Don't believe what the "audio guy" tells you. He's there to make money, we are not. Yes set to small and cross the M80s at 60 or 80HZ. Same with the Cantons if you have not done so.
