    I was wondering if anybody can help me by seeing if im safe running my acoustic b300h head (300 watts solid state) into my sunn beta bass 100 watt 2x15. I also run a fuzz pedal (hoof reaper), belle epoch deluxe, and a pigtronix resotron envelope filter. I also hope to run an mxr vintage octave pedal if possible. Please help me before i blow everything up in my rig lol thank you.

    Is your cabinet 4 ohms or 8 ohms?

    Its a 4 ohm beta bass 2x15 cab with 2 tweeters. It was meant to be paired with the beta bass head

    I have a 1970s B25B 2x15 cabinet that was meant to be matched with a 55-watt B25B Amplifier. I thought I read somewhere that the speakers were rated at 65 watts.

    I used mine powered by my 100 watt V4B for years playing communiy halls and clubs and other places. There is a bit of speaker rattle in there now.

    some past info: Difference between Ampeg B25 and B25B cabinets?

    300 watt amp with a 100 watt cab? Better use a ton of common sense and your ears there bud.

    That's one of the cabinets that used "guitar oriented" speakers. I would be very careful.

    It is? I thought it being a 2x15, that it would be oriented for bass

    I understand i have to be careful but i just wanna know if keeping it at a lower master volume but while using overdrive fuzz filters and octaves would be safe. I plan on using this live but i dont need to crank the master because im not competing with a 4x12 (my guitar player uses a 2x12 musicman)

    Not even close. 15s have been common guitar speakers for 60+ years.

    Read and understand what @agedhorse tells you. He designs amps and cabs.

    Personally, I would use a lower powered head with that cab if I liked its sound.

    Yes, based on the guitar amp series. It was common to use 15" guitar speakers at that time, which is why they are so power limited. Fine for a 100 watt bass amp, but not so fine for a larger amp... which is what you are asking.

    Ok can you explain to me the eccentricities and technical aspects of why it wont work besides just blanket statements. An expert’s explanation if you will.
     
  19. lol, if you want to run a mismatch, that is what makes it safe...
    What other answer were you expecting? When the manufacturer said it was a 100w cab they really meant it was a 300w one?
