Best way to use 3 cabs

LH1000 or a poweramp.

 

GAS list

 

You 8ohm 2x10 cannot be 4 ohms with those speakers. It would need different speakers.

Why are you trying to use 3 cabinets?

Your better off selling one or two and buying a cabinet is the appropriate size.

Do you like your cabinets so much is worth always taking multiple trips on load-in/load-out?

Do you hate your current amp that much?

 

Get a car in B1000 or similar out put stage and call it a day.

 

And cut wattage? I don't think so! That makes adding the third cab a lateral move.

Won't confuse the amp at all as long as it's 2 ohm capable, but would result in a volume imbalance between the two 112's and the single 210. Stuff like that I find very irritating.

Ohmage. And yes, TB ninnies, "ohmage" is a word. Unless your cab specifically says you can change it between 8 and 4 ohms (I believe Hartke makes one you can do this with), you can't change it to 4 ohms. However, it would be a little closer to ideal since there wouldn't be as much of a volume imbalance.

Yes, this is an option.

Personally, I'd use either the two 112's or the 210 by themselves. I don't like how mismatched rigs sound, and there seems to be a fair amount of hoop jumping needed for you to make a rig like that work as it stands now.

 

Nothing wrong with modularity. And I would totally agree that two separate amps are the way to go for what you want. You could do it with a 2-channel amp, but for best results, it's best that each side has its own preamp, and most 2-ch amps share the preamp.

 

GK 800RB amp

It has a low side for a minimum 300watts @ 4 ohms
It has a hi side for a minimum 100watts @ 8 ohms

It has three output quarter inch
Each cab will see at least 100watts

 

A 2 ohm capable amp works perfectly with 2.67 ohm loads. Your informant is confused/misinformed.

All 2 channel amps allow 4 or 8 ohm loads independently on each channel. Many will even handle 2 ohms independent of the other channel.

Are you stacking it all vertically? Accounting for the EQ differences between cabs could be done with a 2 channel power amp and a pair of preamps. Personally, I have found these kind of rigs rarely are worth the bother. Why not get a pair of 212's and call it a day?

Mixing Speakers!?.


In my multiple roles, as a clairvoyant I can forsee a great deal of criticism occurring in this thread in the near future but as I am also the "Ayatollah of Rock and Rolla" I can absolve you of all sin for a small consideration.
As long as you stack all cabs vertically and use a two channel amp with seperate Eq and volume for each cab type.

 

Could you split your signal and run the 2x112 from your current head, and add a micro head or something to run the 210? That would give you separate volume control.

 

I build a speaker series patch box just for this problem. It will allow you to use three or four 8 ohm speaker cabinets and it puts an 8 ohm load on the amp - that is an example- it could be 4 ohm cabs or a mixture. It uses the same method as wiring individual drivers/speakers within a speaker cabinet except it is wiring the Speaker CABINETS in series. its a very simple box and I am trying to sell them on local craigslist- but no one understands what they are I guess. I use them all the time for my bands PA system. Perfect for using (4) 8 ohm monitors on the single 4 ohm minimum monitor out on an powered mixer amp.
If you all think I can sell them here I will. its not really profitable- i sell them for $35. and parts cost me nearly 20 bucks
