Okay, I've just gotta ask. HELP!

[FunkDeBump]

Okay so I know I'll probably get reemed for asking this because I'm sure there's a thread out there somewhere to explain this to me. But I've been combing TB for 2 hours now and I haven't read a thread that has made me 100% sure on the subject so I'm just going to explain-- and ask.

I have a Behringer BB410. Rated at 4 Ohms.
I have a Behringer BB115. Rated at 8 Ohms.

Together it makes a 2.67 load. Right?

So does that extra '.67' mean anything when I'm trying to power these cabs with a Peavey Firebass 700? Am I hurting my cabs or my amp?

I just need a 100% yes or no. I don't want to worry about my gear because I'm not rich and can't afford to replace anything. (obviously considering the gear I'm using, though I'm pretty happy with the firebass)

please help me out guys

I used that same load with GK heads for a decade, then one day my head went up in flames. After the 2nd one went up in fire, I decided to use two 8 ohm cabs. I definitely had an incredibly hot spongy tone that I never got again. Everyone always asked what my secret was.

My best answer is that based on my experiences, I would advise running the proper load. You may get away with it for a decade, or you may cause hell to erupt.

In the Firebass manual, does it say that it is safe to run a 2 ohm load? If so, then the extra .67 means nothing, and you are fine. If instead it says that the minimum load is 4 ohms, then 2.67 is nowhere near close enough to 4.

Yea your kewl.... the manual says ...
• 700 watts into 2 Ω, 475 watts into 4 Ω, 275 watts into 8 Ω
You'll have slightly less than 700 horsepower but you won't smoke it.... Read the bottom of page 6.
Here is the manual.....

If an amplifier is safe with a 2Ω load it will be safe with a 2.67Ω load. IIRC GK amps have a 4Ω minimum in which case any 2.67Ω load will cause the amp to fail, sometimes in very interesting ways.

You are correct Paul, the ONLY G-K amp heads that will handle a 2 ohm load are the 2000RB and 2001RB in dual mono mode (not in bridged mode).

For future reference (From Carvin)

SPEAKER COMBINATIONS and OHMS ( Ω ):

Four x 8Ω cabinets = 2Ω
Three x 8Ω = 2.66Ω
Two x 8Ω = 4Ω
Two x 4Ω = 2Ω
One 8Ω and One 4Ω cabinet = 2.66Ω
Two 8Ω and One 4Ω = 2Ω
One 2.66Ω and One 8Ω = 2Ω
Two x 2Ω = 1Ω
Three x 4Ω = 1.33Ω
Two x 4Ω and One 8Ω = 1.6Ω
One 2.66Ω and One 4Ω = 1.6Ω
