So the answer is pretty much NO.
Time to start a-deciding: Get a head with more umph or a 4 ohm cab. Me, I'd go for the bigger head since I never run 4 ohm cabs, ever.

My name is Rod Johnson and I endorse this message and this thread.
Nope--- capacitors are open circuit to the low frequency signals.
Maybe a flux inductor--- but that movie hasn't been made yet.
I agree the OP's quest is in vain. The second cab nets close to a +6 dB in volume and is the way to go.
But this now prevalent idea on TB that +3 dB is "barely noticeable" is an absolute canard. Especially at high volumes, it is a quite noticeable difference in volume, but even at a low practice volume if you can't notice it it's time to get your hearing checked.
Yes I agree. However, these discussions, in my opinion are really for that new person who just joined. Or who is running into a situation for the first time and is trying to learn more about how his gear works.
If I see a new, ages old discussion, and I don't want to be a part of it, I just pass it by
Well if I see someone saying +3 dB is "barely noticeable" I am going to correct that, because it is well beyond barely noticeable. Is it an earth-shaking volume difference? No. But it is a completely noticeable, sensible, and often useful difference. That's my point, and I am sticking to it.
With the two you could achieve Flux Resonance!
Then you wouldn't need anywhere near the amount power required for a time traveling DeLorean.
You could probably heat your hot tub more efficiently as well.
And that's fine. It just seemed that you were doing more complaining and less explaining.
Why is 3 db more than just noticeable?
Because the smart engineers who devised the decibel scale sensibly made 1 dB just above the JND. So it is by design.
Here is a page that explains it all, with great sound samples illustrating 3 dB differences, 1 dB, and less than 1 dB, where you really cannot hear the change in volume between any two adjacent samples of less than 1 dB difference.

It's a Traynor SB200H and unfortunately Traynor doesn't make any output claim at 8 ohms, only 200 watts @ 4 ohms. I'd guess it's somewhere around 125+ watts @ 8 ohms. I have several 1X10 8 ohm cabinets, so adding a cab is not a problem to get to 4 ohms put I'd prefer to use only one and somehow get maximum output out of the amp. I was only wondering if there was something new on the market that I wasn't aware of to trick the amp into "seeing" 4 ohms.
Number 1 - I never said +3db is barely noticeable. Go back and re-read.
Almost no amps double their output going from 8 to 4 ohms, so we are already less then 3db. Now take into consideration that putting the extra wattage into the same speaker will also result in some of that extra wattage getting wasted due to power compression in the speaker, then you really have WAY less then +3db.

Yeah, using a dummy load isn't really going to help you. If you are getting 200w @ 4ohms, you can guess that the wattage @ 8ohms is probably something like 100w~140w. Using a power soak or dummy load to bring you up to 4ohms means your amp could potentially provide that 200w, but it's splitting between your speaker and the dummy load, meaning you're getting half of the power to your speaker the other half to the space heater you've attached to the output. You're more likely to get more power to your cab without a load that provides no volume benefit.
Oh that's right, you said "almost inaudible". Sorry to misquote that, that *does* make a huge difference. <Eye roll>
Power compression only happens at extremely high volumes, which is exactly where even just 2 dB of difference will be extremely clearly audible. I utterly stand by my correction of this terrible TB meme.
