I should be getting my M60 v2 from the factory outlet soon and was wondering what crossover setting should I set it at? I really appreciate it, thanks.

It's really up to you. Many people set it at 80 Hz; other at 60; still others at 40. I used my M50s at 60 Hz, and I use my M80s full range. Your call!

Okay I gotta try out those settings. Oh yea, do I set the speaker to large or small? I guess small right, because I already have a subwoofer?

Ax, set "small", so that the sub will be mostly responsible for the lowest frequencies, e.g., under 80Hz. If you set "large", the M60s will be run full-range.

I see, it will be set at small.

My current system is m60's, vp150, ep500, and 4 Qs8's matched with a Denon 2805 which only allows for ONE crossover setting. I keep all speakers on "small" with 80hz crossover in the Denon. Be sure to turn your subs crossover adjustment to "bypass" or to its "max" setting to get it out of the way.

Some receivers allow for setting different crossover points for each speakers. In this case, you might be able to have your mains on 60 (I would not go any lower), and the others on 80hz or whatever.

Gotcha! I will set it at 80hz small w/ the sub bypass.

Don't forget to calibrate all your speakers to the same SPL.

Yea about that, I'm going to pick up Radioshack's SPL meter tomorrow. Also I'm waiting for my Avia dvd to come on Thursday. By the way, I have question. Should I wait for the Avia dvd to come before I calibrate the speakers, or should I just calibrate with my favorite song?

Its always better to use a reference disc like Avia. Besides level adjustment it has some good phase tests so you can also make sure the phase switch and level on the sub is optimized with the speakers.

In setting the crossover its important to remember you are trying to find the frequency which yields the smoothest response between the speakers and the sub. The room and position of the sub and speakers will be an significant factor in where that will be. A good place to start would be a half octave above the +/-3db low extension which in the case of the 60s is around 1.5 x 37hz or 55-60hz.

I like to use single sine wave tones 10hz on either side of the crossover or alternatively the LF sweeps available on the Avia disc in the verification section. You're aiming for the crossover point with the least volatility on the metre. Also check at 50hz, 70hz and 80hz, It will vary depending on where you have your sub positioned and your unique room acoustics. When you finally settle on crossover frequency, adjust the phase so you get the highest SPL then go back and recheck the measurements for the crossover to make sure.

Here is one of the better articles on using the RS metre and Avia to calibrate speakers and sub. http://www.bigpicturebigsound.com/article_560.shtml
