    Is it safe to use a Alnico Blue with an 18 watt amp?

    I am thinking of trying one for my Bad Cat Lil'15 and Budda Superdrive 18.

    A Celestion Blue is rated 15 watts.

    It can handle 18 watts to a certain degree, but

    I'd take a look at the Weber, Tone Tubby or Scumnico Alnico's
    rated 30 watts rather than risk damage to a rather pricey Celestion.

    I've heard of more than one person over on the Top Hat forum using a Blue in a 1x12 Club Royale without issue.

    I've used a Blue in my '66 Deluxe Reverb and a '60 Gibson GA-40. I've gigged with the Blue in both amps several times with no problems and we're a fairly loud group.

    I have one in my Budda SD 18 and it works great but I don't run it full out either.

    I never get the mast on the Superdrive above 10 o'clock but I have heard that the volume isn't what kills the speaker.

    The trouble is, that one blissful Pete Townshend power chord and the next sound you may hear is a resounding painful fwap!

    Then again speakers always seem to sound the best right before they fry.

    This is interesting I have heard that not enough wattage with the volume too loud is a sure fire way too kill a speaker, even more so than too much wattage. Does anyone know of any good web info on this subject?

    I have heard the same thing but I have also heard that turning down the volume may not protect the speaker.

    I bought a Bruno UG30, rated at 36 watts, but was recommended to run it through a 2x12 with Blues, which I have. Should I not crank the UG30 for risk of of blowing the lower wattage Blues?

    I would not risk it on a blue.. Sometimes they take it and sometimes not.. Also look at the Red Fang Fang from Emi.. 30 watt Alnico.

    The 18-watt designation is generally the power output during the loudest CLEAN signal. 18-watt amps usually push 22 or more watts when dimed. The amplitude of the power is putting the speaker at a lot of risk.

    That said, it depends on how hot you run the amp. I'd personally go for a 30W AlNiCo Weber or Tone Tubby or a Celestion Gold (50W) if you really need a Celestion.

    If it's that close, how come putting 2 Blues in an AC30 is always OK?

    I believe the Red Fang is now 50 watts.

    I've never understood Vox's willingness to put speakers that are "under-rated" for the application. At least when you've got two 15W speakers (summed up for a 30W power handling rating) for a 30W amp. I guess because amps were not originally designed to max out.

    Like amplifiers, the 15W rating is RMS not peak. It can handle higher peaks, but prolonged operation at sustained power levels beyond its capability will cause it to fail.

    Blues can handle and take more than most think...

    But,

    If there is any doubt, how about a Gold if you want to stay in the Celestion camp?
