    Hello! I am considering to buy a second hand mark bass little mark 250 blakline which delivers 150 w into 8 ohms. The problem is that I own a GK 410 rbh cabinet and it is rated at 800 W. Will I be underpowering the cabinet?

    There's no such thing as underpowering.

    I once used my H&K head in its 5W setting with a cab that is rated 600W.
    I'm glad i escaped alive!

    On the road home, i drove my car, which is rated at a topspeed of 190kph, at only 70kph.

    Yep, another one saved.
    PS. Once I used my electric toothbrush on the low setting...I'm okay. :)

    I once went to an "all you can eat" restaurant, I didn't eat all I could.

    I ate all I could. But every time I was about to finish everything they served even more to eat. So at least I gave up.

  10. This is my 130w Peavey head into my 800w Ampeg cab. Works a treat and sounds awesome!

  14. Underpowering is not, I repeat, not, a thing.
    What you will have is speaker headroom up the wazoo.
    It's all good.

    Yes - but it won't hurt it. It just won't get really loud, and therefor will likely not sound great.
    Get something that matches your cab better - a 500 watt head like a Aguilar TH500 would work nicely.

  18. 150 watts and a 4x10 might get kind of loud.
    That's more than Sir Paul had at Shea Stadium.
    And yes they were into the house system, but it had the frequency response of a dial up phone line.
    That's OK though. No one ever went to a Beatles concert to hear the music.

  19. Forget turning it down, what would happen when you turned the amp off and power went to zero! Doom!!

    Ok we're all being a bit snarky OP but you get the point. Underpowering as some sort of speaker destroying monster is a nonsense myth.

    150W into a 4x10 can get plenty loud - UNLESS the cab is rated for 800w which means it's designed to be driven by many more watts that 150.
