Fender Rumble Club

As far as I know all amps distribute their power evenly between the cabs plugged into them. The only exception to this rule is when they're driving 1 cab. In that scenario an amp will have access to it's designed power rating at those ohms. Well do an example with a Rumble 800HD.

1 Cab = 400 watts @ 8ohms/ 800 watts @ 4ohms = 400/800watts per cab depending on ohm rating
2 Cabs = 800 watts @ 4ohms / 800 watts @ 2ohms = 400 watts per cab
3 Cabs = 800 watts @ 2.67 ohms = 266.67 watts per cab
4 Cabs = 800 watts @ 2 ohms = 200 watts per cab

Now each cab will divide that power evenly as well. So we'll look at your specific cab pairing and I'm going to assume the WT400 has 400 watts of power @ 4 ohms because I'm lazy and the math is easier. (That and it's ability to run at 2 ohms is why I used the 800HD in my above example.)

400 watts / 2 cabs = 200 watts per cab.
Cab 1 = 2 speakers = 100 watts per speaker
Cab 2 = 4 speakers = 50 watts per speaker

I'm sure there's some amp and cab out there that uses fancy tricks to get around this but in general this is just how electricity flows from amplifiers. Essentially that meant your Eden 210 was working twice as hard and those speakers with those settings clearly didn't like it. They could also have been mismatched cabs and the farting was more a result of phase cancelling or some bad coupling effects.

I had something similar happen with my old Peavey stack. The 210 was garbage and ruined everything and it was only after I sold the 210 that I realized the 115 didn't sound half bad. But that 115 also wouldn't fit in any car. SUV/wagon/truck transportation only, and it weighed more than an EBMM Stingray on top of a Rumble 800HD on top of a Rumble 410. Anyway I'd just chalk it up to that Eden 210 wasn't so good or didn't like your Eden 410. No wattage trickery there. The Line6 for whatever reason just was a better pair and/or had better speakers.

Thanks for all of that. Yes the WT400 is 400 watts at 4 ohms. The 410 and 210 were 8 ohms each. As it turns out the 210 speaker cabinet was an old design and not very good, even by itself. With the experience of the Line 6 210 combo I was wondering if there was some sort of circuitry or magic that would some how distribute watts to even out the 410/210 scenario. But better speakers sounds more likely.

So a Rumble 210 with a 115 or 210 extension should be fine. But I wonder how a 115 or 210 combo would work with a 410. What does Fender do to match these combos and extension speakers?

... ... I used an Eden WT400 with a Eden 410xlt cabinet ... .... I added an Eden 210 cabinet once and it sounded like crap because the 210 ended up with most of the wattage and farted [out] all night long.

However when I put my Line 6 210 combo on top of the 410, using the 410 as an extension speaker, it sounded great! So good in-fact that I did this for about a year.

Just wondering if the Rumble (or maybe all combos) work like that.

See the TB FAQs in the Amps & Cabs section for lotsa background info on this topic.​

"Something" about your Eden 210 was evidently the problem. How did you determine that the 210 got most of the wattage? Farting out is not necessarily a power imbalance. A lower impedance on the 210 than the 410 would normally pull more power from the amp. Otherwise, a malfunction, a mis-wiring, a low power rating could explain it. You must pay attention to the specs when connecting amos & cabs.​

No, not all amps & cabs work like your bad experience, as you found out with your Line 6. The Rumbles are specifically designed to play well together, as are most quality brands. But mixing brands can introduce imbalances.​

Gross oversimplification, there BBassy! It's all about the electrical balance of the speakers without any regard to the number of cabs they may be in. :eek:​

That appears to assume 8 ohm cabs all around, which is not always the case. There are reasons for 4 ohm cabs, as well, though they can be misused. And there are power ratings to help avoid mismatches, as well. A low power rated 210 could explain juan's situation.​

The Rumble cabs are designed to be electrically compatible and tuned to sound good together.

Good point! I only know electrical design from the standpoint of gross oversimplification so it's good you chimed in as well!

As G-Dog says all the Rumble cabs have been designed to work together. How they do it involves a level of maths I am not capable of. (Literally, math is the reason I'm not an engineer.) But whatever you do pair will work. We've seen every combination in this club too. From a 200c + 410 to 2x Ampeg PF20ts running 4 Rumble 112s. No one's complained about their pairings.:cool:
