Pros/Cons of biamping the MMC6500s..

Next question! What are the pros and cons of biamping the MMC6500s either with or without the crossover? I want the cleanest power I can get out of my amp (A PG Octane R 8:0:4), but I also want to protect the drivers. It looks like I have three choices:

1) Bridge the amp and drive the speakers "normally"

2) Biamp using the crossover network

3) Biamp it using the amps crossover

So what is the best bet?

    does that amp have a crossover frequency high enough to bi-amp them?

    How would you biamp using the crossover? The only thing I can think of is having a seperate crossover for the woofer and the tweeter and hooking each up to an output of the amp.

    The MMC6500's X-over has dual inputs. One for the tweets and one for the mid. Perfect for bi-amping!

    The pros of bi-amping are it offers you oodles more flexibility in tuning the tweeter output. How accurate do you think 0,-3,-6db is going to be as opposed to being able to adjust a gain control to find that sweet spot. I will dare to say that you can ALWAYS get better SQ out of a set of speaker by bi-amping as opposed to straight wiring.

    The cons are you have to fork over extra scratch for a second set of RCA's and speaker wire. Not to mention more wire to run.

    4 channels are usually more expensive than 2 channels but a 50x4 is usually the same price as a 100x2.

    I dont like bridging a 4 channel because it makes the amp operate at 100% power which means more heat and distortion. Bi-amping will have the amp operating at a much normal output level which will be less distortion, less wear and tear on the amp and less heat.

    I only wish they would setup the MM6 x-over like that. I believe the MM6 is a much better speaker, why not make it as flexible?

    The MM6 was designed years ago and no one thought of it then.

    Have you used the new MMC6500 or MMC5250 yet? I lke them better then the MM6.

    This is something Ive been wondering for a while now. Is the MMC6500 a better speaker than the MM6? I was under the assumption that the MMC6500 was just an alternative to the coaxial and that the MM6 was the "serious" speaker.

    I would think the MM6 is the daddy what with its higher power handling and all silk tweeter.

    Ive heard the MMC at my local Tweeter and think they sounded better than the $570 set of MB Quart Premium! (However they dont carry the MM6 so I couldnt compare the two) My only concern is with the tweeter. From the specs I would think the MM6 tweeter is a better, smoother sounding performer.

    I guess my question is, I thought the MMC was just the coaxials MMC650 pulled apart and being sold with a better x-over but using the same tweeter and midrange as the coax. Is this the case or is the MMC6500 built with upgraded materials over the coax and thereforean equal if not better speaker than the mighty MM6?

    The MM6500 has the same mid as the MMC650, different tweeter, different crossover. The MMC6500 tweeter is very similar to the MM6.

    Beautiful!!

    That was my only reservation really to the MMC6500. I love the way my MMC690 mid sounds, I just always thought the tweeter was a little puny. But if the 6500 uses the same mid but an upgraded tweeter then Im all set! :D

    The MMC690 is different than the other coax's, since it's the only 3- way. The 570 (non- swivel), 525, and 650 all have the same tweeter.

    Well then youve talked me into it. Ill be looking at the MMC6500 rather than the MM6. Which is ok since Tweeter doenst carry the MM6 for some odd reason?

    I dont know but both Crutchfield and Sound Domain are still selling them and its way passed the point where they should have all of last years models cleared out.

    It's not officially done yet but with the new components now available the MM6 is as good as dead.

    LOL! Yeah, I admit Im not reall happy about it either.

    Regardless which is the "better" speaker, the MM6 just seems cooler. Plus it has less letters so its easier to type!

    On a good note, that means they will be going on SoundDomain for dirt cheap pretty soon, just like they do with all their discontinued stuff.

    Now if only Xtant would discontinue their 4.4. and 6.1!
