Modify my mono cabs to stereo?

Well, impedance can be a tricky thing since it varies with frequency. Fortunately, most manufacturers take that into consideration and underrate their speakers. It also isn't rocket science. One is typically safe if one is in the ballpark/wheelhouse. ;)

I have been known to run 2 16 ohm cabs on an 8 ohm transformer tap, or 4 16 ohm cabs on a 4 ohm transformer tap.

Well, yeah if you're running them in parallel. A hundred watt head with a 4 ohm minimum can push 4 16 ohm 4x12 cabs. Or 2 8 ohm etc. That's why many bass heads are rated at 2 ohm minimum.
It's my understanding that as ohmage increases, speaker response tightens up. 4 ohm cabs work great for classic bass or blues. Not so much for modern death metal.

It has been my experience that a crap ton of 16 ohm cabinets is the way to go. YMMV.

Nominal impedances are a good general guide, especially since our guitar cabinets usually do not have crossovers in them. Elaborate crossovers in hi-fi speakers can make the impedance do crazy things in some frequency ranges. And remember: Its not just amplitude. Its phase angle, too.

Isn't that part of the principle behind the Sonic Maximizer? Some think that's all bunk.

Yeah, but guitars don't necessarily have the frequency range to benefit from a crossover. Right?

It has been my experience that more speakers, moving more air, always sound better. Hence the full stack over the half stack.

I think the strings, pickups, pedals, and preamp sections generate some appreciable energy at those higher frequencies, but it tends to sound unpleasant when it is reproduced accurately. The work that a guitar cabinet (or emulation, FIR, etc.) does is important: It gracefully attenuates those frequencies by virtue of not being very efficient at reproducing them. It is a giant paper midrange, not something you would send to do the work of a tweeter.

I will still disperectiffuly disagree that it won't take us out of the midrange where no crossover should be required.
 
Little Pigbacon said:
I am still not getting it. My pedals wont take us out of any frequency and no crossovers would be required. Can you state it in another way?

What frequency range do your pedals cover? My suspicion is above what a low crossover or high crossover would be required. Of course to quote the legendary Hank Weldon, I've been wrong before, could be wrong again.
 
A crossover is only going to help if your signal is below a certain frequency or above a certain frequency, I don't think guitars will reach either of those. Again, bless you Nancy, I've been wrong before and I could be wrong again.
 
Before you ask, the best sound engineer I ever had. And yes, I would have paid to l.ck her. Well, you know. Didn't need her to feel whorish. She was definitely not that. Totally top shelf, and if I was on the road again I would get down on my knees and beg her to be my sound engineer today. I'm sorry Nancy, I'm much weaker than you girl.

All my pedals have been specially modified to work only at 60 Hz. If I turn it up loud enough, I can run my refrigerator off of it.

Crossovers only pass your signal above or below certain frequencies. If your signal is not there - who the f cares? A crossover will take the same approach.

Edit is not a good choice. They will pass your lows on to your woofer and your highs on to your tweeter. Again, assuming all of these are available.

Edit: my first choice of wording attenuute sucked

Some bass amps are brutally powerful and stable into 2 ohms, like car subwoofer amps or some shit. Freakin six 6550 power tubes, etc.

Peavey Firebass 700 into two 8 ohm cabs along with a 4 ohm. The 2x15 is running with the guitar.

Definitely a world needing help girl. Maybe come out of retirement and save part of the world, and I love you girl as you'll also be trying to raise a family. All my best JP
