Um...Ohms??

[JimmyM]

boy, you guys really suck at conveying information

ok, so here it is in layman's terms. you may use only the berg or only the schroeder in your lmii. if you ever get a second 8 ohm cab, you can use it with your schroeder in the lmii. you may NOT hook up both the berg and the schroeder together.

awesome, thanks for the feed back!

Easy formula: (multiplication / addition) >= amp rating

Say an amp rated at 4ohms. The combination of resistances (cabs) has to be greater or equal than the amp rating.

Two 4 ohms cabs: 4x4 / 4+4 = 16 / 8 =2 ohms (wont work)

Two 8 ohms cabs: 64 / 16 = 4 ohms (will work)

One 4 and one 8 ohms: 8x4 / 8+4 = 32/12 = 2.66 ohms (wont work)

You sure can connect a 500 watts amp to a 1-8ohm cabs, but that will only give you 250 watts of power.

2-8ohms cabs will give you full power.

Cannot be more digested than this.

That's incorrect. The Little Mark puts out a maximum of 300W into an 8 Ohm load.

C'mon, man. I thought mine was pretty danged clear and comprehensive.

 

[crow01]

250, 300 watts, like if there is such a difference.

and the original question was what? How much does the Little Mark holds?

 

[David Jayne]

would not the 4 ohm 6x10 be loud enough with the LMII??

Yes. It would be loud as he**.

 

[JimmyM]

C'mon, man. I thought mine was pretty danged clear and comprehensive.

comprehensive, yes. i have a feeling you guys were making his brain hurt over the possibilities, though

 

[alexgeddy]

not to throw a curve ball lol.... but 8 ohms measured on a speaker is about 5.397 or something. not 8 ohms dc....just a thought

 

[slyjoe]

Yes - you always need to measure DC resistance of a speaker to 3 decimal places.

See post 9.

 

[alexgeddy]

Ya know i wasn't even thinking of that when i wrote it. Maybe I should see what it is out to 6 places!!!

Maybe i shoulda just put 5 and a half ohms....but the intent was to make sure somebody didn't measure an 8 ohm speaker and think it was bad.

i played a 4 ohm and an 8 ohm mixed for the first decade of my playing life, and i used a GK 400RB head and three 15" speakers. sounded great, super hot and spongy. then one day my amp caught fire. after i replaced it, the speakers just sounded "worn out", like they were worked to death, which they actually were. i would heed the advice given here and NOT do it. those old GK's were some hard working muthas too, and withstood tons of abuse. get another head, sell and replace a cab, just run the impedance correctly if you want to avoid problems.

 

[babebambi]

mmmMMMmmm.... I think the rating you see for bass cab is (nominal) impedance rather than resistance ...

 

[alexgeddy]

You are right the 4 and 8 means impedance but if you measure the cab inet with a multimeter, you won't measure impedance but DC resistance, whicjh will be lower than the 4 or 8 ohms impedance. this is the only point I was trying to make ...possibly to save somebodey from thinking they had a bad speaker when they measured a lower value than 4 or 8 ohms.
