MIxing cabs is bad. Including these two?

How about coupling an RS210 and an RS410 each at 8 ohms?

Same company and same drivers. Just a different box. Right?

Not the "same" speakers..............

The 4X10 cab is *most likely* 8 ohm speakers configured in series/parallel.

The 2X10 cab is either 4 ohm speakers in series, or 16 ohm speakers in parallel.

Additionally, even if the speakers all perform the same - you are going to be sending twice the power to the speakers in the 2X10 then the speakers in the 4X10.

When mixing a 4X10 with a 2X10 it is better to use a 4 ohm 4X10 with an 8 ohm 2X10 (however, you need a head that handles 2 ohms)

OH. Bummer.

Even though the ohms rating of the speakers are different - they are going to be closely matched in the rest of their T/S parameters.

Also, there are many that do run a 4X10 and 2X10 of matching ohms without incident.

You just need to be aware that the 2X10 is going to be getting the brunt of the power, and will be your weakest link. As long as you know this, and pay attention when the cab is telling you it is straining, you should be OK

OK, but not perfect. An 8 ohm 4x10 and 16 ohm 2x10 would be loaded with identical 8 ohm drivers, and that would be perfect. You should be able to get a 16 ohm 210 special order, since they already have the drivers. That doesn't mean that you will, just that you should. If they offer a 4 ohm 210 it also has the same 8 ohm drivers, you'd just have to rewire them in series to get your 16 ohm 210.

No. I have a 210 cab that is 8 Ohms. I wanted to add a 410 cab that is 8 Ohms also. Running at 4 ohms. I just thought being everything was TC Rebel Series that it would work out together as opposed to trying to run a PS112 and an RS210 together.

Then you'd need a 4 ohm 410 for perfect matching. And of course a 2 ohm capable amp.

Youngspanion · #8 02-03-2011, 12:20 PM

Wait a minute. I don't think something is clear here.

I have a RS210 Cabinet. Its 8 Ohms.

I want to get an RS 410 cab. 8 Ohms.

Together its a 4 ohm load. LittleMark 2 head. 4Ohms. No problem.

OK. That much we all know.

My original post was this:
Mixing cabs is usually a bad idea. I wanted to know if, in this case, its different being the two cabs were from the same company. With each having 10 inch drivers.

In this case, as you say, you're not really mixing speakers -- you're essentially ending up with a 6 X 10, a seemingly increasingly popular configuration. The problems are with mixing cabinet impedances, such that the 210 cabinet speakers will each be seeing twice the power of the 410 cabinet, putting them at some risk if you push too hard.

The other issue is the same as with all cabinet configurations having side-by-side speakers -- limited horizontal dispersion of mids and highs, essentially. For my money, I'd get another identical 210, stack 'em as they're designed to be in the case of this cabinet, and you'll be away. You'll still be plenty loud enough to cause permanent hearing loss, if that's your aim.

Youngspanion · #10 02-03-2011, 12:56 PM

Yes. I want to be one loud ass bastard and clean and clear sounding too. No compression like I get now when I turn up too much. Thats the drug of choice now.

get a 4 ohm, 4x10 use it when you want to blow the paint off the walls. Keep the 2x10 for when that isn't appropriate... While I basically *hate* 4x10's - the one thing they do right, is to work as a 'violent' monitor when you are up close & personal with one ... properly driven and aimed, you really shouldn't need the 2x10. Equip the 4x10 with a tilt style handle on the bottom so it doesn't just blow past yer butt...

Another thought... For quite a while I ran a pair of Bag End 2x10's, stacked vertically to get better monitoring - think 1/2 of an Ampeg 'fridge'... I drove it with a GK 1001 RB II at 8 ohms (2 x 4 ohm cabs in series) - having that top 10 up by me head really helped a bunch on smaller stages. Apparent volume vs absolute...

If you could borrow another 8 ohm 2x10, you might find that an interesting experience.

this. ignore all others. those cabs were made to be stacked vertically, which decreases dispersion and such, and still gets you all the volume you'll ever need.

a vertical 4x10 will give you nearly as much volume, you will be getting 200 more watts out of your amp and the amount of air being moved will be doubled.

I think you meant to say increases dispersion.

What do you mean a vertical 410? Isn't it a square?

The total input will be limited by the capacity of the 210. Is it bad? No. Is it ideal? Also no. I agree that adding another identical 210, stacking the two vertical, will work just about as well as adding the 410, saving both pack space and bucks in the process.

2 x 210s stacked vertically.

Bill, can you explain what you mean about the total input being limited by the capacity of the 210?

I don't understand.

Both cabs are 8 ohm. That splits power equally between the two, half to the 210, half to the 410. When the 210 reaches its limit that's all she wrote, even though the 410 will be only at half its limit. Which begs the question: why pay for four more tens to only get the output of two? Actually it's bit more, but not enough more to make schlepping and paying for a 410 worthwhile IMO.

father of fires · #20 02-03-2011, 01:48 PM

It is not technically wrong to use these different cabinets. Each cab will get half the power. It's that simple. It will sound great and probably be as loud as you want it to be but, it will not be as efficient as it could be. Some of these guys opinions (especially BFM) will help you get the most out of your head and current cab. These are great ideas but, they are most certainly not rules. Outside of Talkbass this kind of talk falls on deaf ears.

Good luck with whatever you choose to do.
