Full range break in

Let us say for the sake of the argument that there is a difference. The usual range would still be broken in. The only way you would hear a difference is to change and try and see. So break them in the way they will be used. 

You do not by the way want to cross over the way you said. The most beneficial thing with subs is to have the low bass coming from more source locations. Removing the low bass from the main pair removes two source locations. The opposite of what you want. Its better to run the main pair full range.

mc - I am running the same Dayton SA 1000 as you but only using one.  Also running 4 separate subs vs your 5.

Is turning down just the Frequency knob (the one between Phase and Gain) all that's needed to allow full range?

Congrats again on the Moabs!

The Dayton runs off your pre-amp (or sub) out. The knobs you're talking about affect only the subs connected to the Dayton. Your main pair is unaffected. They are running full range. Which is what you want.

As far as break-in goes, the Dayton amps being SS can be left on all the time. I leave mine on all the time. Except when they will be off for a long time, like waiting for Moabs! 

Speaker break-in is just like everything else break-in. When you hear the sound getting better night after night its breaking in. When it sounds the same night after night its done breaking in. Yes it really is that simple. 

Thanks mc!
Any updates on delivery?
Interested to know if the Moabs (with different woofer configuration vs your Talons) might dictate moving around one or more of your subwoofers.

Also, I have had great results elevating 3 of my subs and facing them toward the ceiling with 4", 10" and 15" clearances.

Wondering if you have tried or considering trying this as your listening room is much larger.

Everybody keeps asking the same question. There’ve been four speakers in there so far. One of them I labored many hours trying every combination of speaker/listening only to have them wind up right back where the first set sounded best. When I got the Talons they went right in the same spot. When I get the Moabs, guess what? Right.

If it ain’t broke....  

There simply is no reason to think they would be any better anywhere else. The bass I am sure will be a lot better, if for no other reason than the additional woofer up high. At that wavelength the two are effectively one. (This same principle applies to the tweeter array, which is why it does not have the comb filtering some mistakenly think it should.) But to the extent it is higher it can only help, in the same way having more bass sources always helps.

I would probably be eager to try some of those elevating tricks. If things weren’t already so good. I’m a low-hanging fruit kind of guy. The Moabs will go where the Talons were. They will be tweaked for toe and symmetry. They will be painstakingly level to within a gnats, uh, hair. The sub levels will all be tweaked to match. Might not need to do much though. It would seem they would need to be turned down. Then again the Moabs are a good 6 to 8dB more efficient than the Talons. Whatever. I have set up enough speakers in that room to be surprised if these are any different.

I mean, other than being a whole lot better!

I think it's really just a matter of time.

The issue from measurements of woofers I've seen is the suspension is a little too stiff at the beginning, and the resonant frequency of drivers drops afterwards.

Since the problem happens at the low-end of the speaker response, it's kind of self-healing.  I mean, if you use a sub, you'll never notice the speaker breaking in, but it will, only it will take longer. 
Just play your speakers as you would normally.  At worst, you'll take a little longer if you high pass them. 

Thanks!
Happily breaking in!
