Is my Boogie putting out more bass than my speakers can handle?

[mrid]

When I set my graphic EQ on my Mark IV in a "V" shape and play on the clean channel, my speakers "woof" and "fart" on the low strings. I have my amp set at ~30 watts class A into a 60 watt cab loaded with a Celestion V30 and G12H-30. The speakers are fairly new, so it could be a break-in issue...or am I just boosting the low frequencies too much...I just love that scooped clean sound! :laugh2:

I think every cab has an amount of bass it can handle. too much and it sounds bad. I made the experience some cabs can handle more bass than others...
i heard about modding a cab to make it "stronger"...

Are you tuning down??

Nope, standard tuning /w 6 strings.

Can we assume this only happens when boosting the bass frequencies with the graphic EQ?

Just turn the bass down until the woofiness goes away

You're running into the problem with 2-12's vs. 4-12's. They just can't disperse that much energy! Only the 4-12 will take that much low end. One thing that may help is to put a lining of Corning insulation on the inside of the back panel, if it doesn't have that already. I have two Bogner cabs, a 4-12 and 2-12 large. It's a fair A/B comparison to make, so I always use the 4-12 since it has a bigger dynamic range.
It just handles the lows much better.

Sorry to invade...but how much gear do you have MRID!??!?

Not that much! I go through a lot of amps to find the right one. :laugh2:

LOL...seems like your always selling something....why don't you just list us your gear eh?

That also could explain the farts.....how is it in normal mode??

Exactly.

You're using to much bass.

1. Are the speakers of the same impedance? Does the final cab load equal the output of the amp head?

2. My money is on the G12H30... Your amp may be over powering it slightly, causing it to over extand. It may not have the excursion to recreate lower frequencies at higher volumes.

Yeah and the overdone bass may also need a reset.

I think the problem is that 2-12 cabs were originally designed for 40W amps, and are only capable of a certain amount of bass. The same thing happens when you run a 600W bass amp into a 4-10 cab. Those 100W Mesa's are powerhouses! They almost need a 4-12, if you're planning on using those heads to their fullest potential.
When I put my Ecstasy on my Bogner 2-12, I've got to dramatically back it down, or that head will turn the 2-12 into a small pile of sawdust! LOL

1. Are the speakers of the same impedance? Does the final cab load equal the output of the amp head?

Yes, the speakers are the same impedance. The final load is about 2x the output of the head.

I know I could just turn the bass down, but I'm wondering why a guitar amp would have this issue? I've just never run into it before...

It's a Mesa, and Mesas have a huge bottom end.

I find if I put my bass up too high (Dual Rectifier) it distorts in a bad way, and it sounds similar to what you're describing. The higher my gain goes up, the lower the bass has to go. I figure it's because when the bass is up that high, it starts to clip the tubes too hard and turns your nice distorted sine wave into a square wave or something. It's the price of retardedly high gain heads I guess.

I also find that if the gain and the channel master are both up high, it tends to "fart" more, so I either turn down the bass, or the channel master, but usually it's the bass, because I like to push my power amp hard.
