Whoa Nelly! That's a lot of amp for a pair of 4 ohm 1x12s. Take care and keep it between the ditches.

they are 500 wats a piece and at 2 ohms the db751 is 975 watts... thats less than the 2 cabs rating...
Yeah, but they're single 12's. That 500 watts won't apply to the low bass end. 150 watts of clean bass is very good performance for a single 12.
Your DB751 could send a pair of 8ohm 12's into distortion in the bass end, and possibly kill them if not used responsibly. 4-ohmers....watch out.
That's 500w each THERMAL rating - NOT real world bass frequencies.
i hear what you are saying, but who really uses all the power their amp is capable of putting out? i don't, i just like the fact that i can use the 2 ohm output! if there are no reasons for a 2 ohm drop why is it made? i never understood why 2 ohms is used on amps? i have a schroeder 212pl 800 watt cab, hifi as hell, sounds incredible, but i think the DB would sound good through a gorilla amp..
Just because an amp can do 2 ohms doesn't mean it has to run that way. That's so you can keep adding more cabs if you need louder, and so it's not running to it's max abilities on more common 8 or 4ohm loads. That helps with reliability. And no, it's not doing its 1000 watts if it's not cranked up to full power. Can put out more than that if run into distortion.
Just saying be careful and don't come back with a thread titled, "how did I blow my speakers when they're rated more than my amp?".
That amp will make a pair of 8-ohm 12's give you all they can give, and allow you to add two more if you want more loud.
The bottom line is that you can use your two 4-ohm cabs if you want to. If you want to avoid blowing 'em out, you'll need to be very careful with your EQ and volume settings, and your right-hand attack on the instrument. And you'll need to keep a sharp ear at the ready to pick up any signs of speaker distress.
But practically speaking, you're realizing no more amp output by using your 4-ohm cabs than you would by using 8-ohm cabs. The limit is the limit. And once your cab has hit its performance limit, it doesn't matter how much more power the amp has in reserve.

i dont plan on ever really using the 2ohm capabilities! i like the idea of being able to if i ever needed to... its kind of like the mustangs in the 90's they were 225 horse motors on a crap frame? all the frames of a used mustang gt were bent! but, but, the horse was there incase you needed it, was it good for the car? so as i see it, the 2 ohm load i probably will never use, worse come to worse ill just drop in an 8 ohm 12lfc...
If you've connected two (2) 4-ohm cabs, then your amp is already running @ 2 ohms. That's the way impedance works. It doesn't matter whether you "plan" to use it. It's already there. The only question then is, how well will you be able to manage all that power @ 2 ohms?
MM
Volume knobs aren't that hard to operate. I've used very high powered amps into single 1x12 cabs in the past, and the magic smoke has never escaped.
I personally have never had a problem with it either. Yet cases of inadvertently overpowering small cabs are as perennial as spring flowers. Apparently it must be a problem for some people, else it wouldn't keep happening.

This threads goin off the techinical deep-end a bit... I'll be looking for some in-depth reviews from people who are using the cab in gig situations, hopefully with a good variety of heads. I like my SB112 NEO (tweeter) but I probably would have bought this one if it was available at the time. Mine's in Blue Tolex so it's looks GREAT. Since it's fairly large and ported, it sounds a bit rounder than my DB1260, more like a classic 15" cab.
A matching 12/6 with say, a 500w micro head would make for a sweet rig.

people, i am not currently running 2 ohms!!!! if i choose to i can! thats the premise of 2 -4ohm cabs!
In cabs with a real crossover (which includes a filter to roll the treble out of the woofer), it involves more than just "dropping in" a different impedance woofer. The crossover needs to see a particular impedance to work right, so the crossover must be changed too.
Much better to buy the right cab to begin with.
I'd just get a fleet of SB126's. Pile up however many you need to make enough rig for the gig.
A DB750/751 and 3 or 4 of these things would be a huge sounding rig.
2 of them, turned up a healthy bit, would carry the room at a typical rock small bar gig. 3 or 4 for really big stuff.
I could run four 8 ohmers with my Carvin BX1200, two on each amp, at 200 watts each cab. That would be pretty cool.

And I've got an Eden Nemesis RS700 rated at 700 watts output @ 2 ohms. So it would ostensibly deliver up to 175 watts per 8-ohm cab.

I saw they are doing the 2x12 with the mid-driver too.
So, have they worked out all the questions about the cross-over point?
What is the frequency range of the mid-driver?
I see there are options:
1.6k hz or 2.5k hz cross-over.
Eminence Delta LF 12 ceramic speaker.
Eminence Kappalite 3012LF neo.
Faital 12PR300 neo.
What driver and cross-over point are you all thinking works best, without putting a strain on anything?
Is it worth it to spend a little more for the Faital or Kappalite? Is their performance justify the small upcharge?
