is there a 4 ohm cab that's rated 500 watts?

This is true. OTOH one kickass single 4 ohm cab that can take better advantage of your amplification that is 4 ohm capable might be preferable. I use a single 4 ohm cab everywhere because it works and I'd rather not have to carry two cabs around to get the same job done. And my one cab is overkill for the majority of my gigs.
On the other hand, there can be advantages to a pair of smaller cabs rather than one bigger/heavier one. (1) Some of us would prefer to carry two 1x12s or two 2x10s than a 2x12 or 4x10. (2) Sometimes two smaller cabs are easier to fit into a car or trunk than one larger one. (3) You can bring one cab and leave one at home when you don't need both. (4) And if four 10s is what you what, there are advantages to vertically stacking a pair of 2x10s rather than using a 4x10 box. (Personally, I like this arrangement so much I have two such rigs, which I keep in different places -- one a pair of Avatars, the other SWRs.)

It doesn't ?

Clearly marked 4 ohm minimum, outputs parallel....................

Which is why I don't use a bigger/heavier single cab.

well now..that just all depends on what kind of amp you have..I am running two ampeg SVT HLF 4 x10 cabs (4 ohms each) with my SVT Pro 4 amp..you can also run two 8 x 10 cabs ( 4 ohms each)..I am running dual parallel mode not bridge mode..A and B channels for speakers use independent amps in dual parallel..this amp will also let you run 2 ohms at each speaker channel in dual parallel...but you can only run 4 ohms at bridge mode..

I own four 4Ω Acme B2 2x10s. I chose 4Ω because all of my amplifiers have dual output channels and each are stable at 2Ω. The vast majority of bass amplifiers are only safe down to 4Ω, including the OP's unit, which is why I wrote what I wrote. :)

Thinking that a 4Ω box will be significantly louder than an 8Ω one is a fallacy!

Thinking it can't sound substantially nicer is a fallacy too, especially with certain modern Class D amps. As always, just IMO and IME.

:roflmao: says the guy wit a 1000000000000000 Watt rig!

Sorry Paul :) I could not resist! :D

A big part of "nice" and "nicer" is loud ;)

Definitely can be, or we might just perceive it as headroom. Plenty of people buy 800 watt amps instead of 500 watt ones, but they only get a couple of dB louder, right? As usual, just depends is my final answer.
 
I AM talking about nominal impedance rating, not dynamic.

If you have a cab with one 8 Ohm speaker that 8 Ohms IS the nominal impedance.
If you have two of those speakers in a cab the nominal will either be 4 or 16.
If you have three of them the nominal must be 24 or 2.67. (Assuming they are wired to all get the same amount of power.)
Double that to six speakers and you have more series parallel options but you never can get to 4 ohms nominal, not with speakers of standard nominal ratings.

You might come up with 3.2 nominal or 5.6 nominal as a couple of examples, but 4 Ohms nominal where all speakers are receiving equal amounts of power won't happen unless the speakers are all of a non-standard NOMINAL rating.

The nominal rating is what you should be using when deciding how to pair up cabs with amps.

Are the manufacturers just fudging this number to sound like something most folks understand?
Just like they round up power ratings? Who wants a cab rated for 392 watts when one "rated" for 400 will sell much better?
How many people who don't understand nominal vs dynamic impedance would shy away from a cab rated as 3.2 or 5.6?
How many more TB questions from noobs would there be when we deviate from the standard of 4 and 8 Ohms.

Given the number of people who don't understand impedance or power ratings, it's no wonder the cab manufacturers would rather just jiggle the numbers a bit rather than cause even more confusion than there already is. And if that's what's going on then that's all I need to know.

As an electronics tech, it is important for me to know as precisely as possible what is really happening with my gear.
Fudged numbers are the bane of our existence. If we know the numbers are a bit off, we can deal with that as long as we know how far off and in what direction. But a 4 Ohm cab with 6 speakers, and nothing else going on to explain it. :rollno:

It doesn't hurt my feelings too much.

But I know what you mean.

Technical yes it's a 6 ohm cabinet.
But they are saving alot of hassle with the general public.

Cause people flip out and still have enough problems wrapping their heads around common 8 and 4 ohm cabs.

You throw a 6 ohm cab in the mix. People just freak out. What about this ...what about that. Will the earth stop spinning and will my grass turn less green lol.

Easier just to say it's 4 ohms.

If I was selling a 6 ohm cab. I'd would like to say it's a 6 ohm cab. Simple enough.

Then just expect a slurry of confusion and hesitant buyers. From probably 60% or more.
So it's easier to say it's 4 ohms

I have no opinion about this, but can't resisting noting that "Slurry of Confusion" would be a great band name....

Lol yeah. Not to bad of a name.

Your screen name reminds of a huge neon lobster sign , a restaurant had in my old stomping grounds.

Our friends spoke so much of the neon lobster. Eventually they used it as a band name.

And to stay on topic. I'll throw in a typical answer. I know a 4 ohm Ampeg 810e handles 600 real watts. So the 300 real watts from a 500 watt head would be fine lol
