    How will a Marshall tube amp (or others) react to a passive crossover being installed at speaker level?

    Thinking I could build a couple different ones to recreate the EQ curve of different speakers


    say I have V30s and want to mimic the EQ of a Greenback or 75

    Ive built many for audio use and have all the parts...just curious how a guitar amp would respond

    Anyone know the EQ differences between a V30 and a Greenback

    I know breakup and other factors cant be mimiced...but the overall eq is what Im after

    thanks

    I guess I should rephrase the question

    How would a tube amp respond to a speaker load that had a cap or choke in its path?

    Would it be fine or cause damage?

    Tube amps are used in audio apps all the time, with crossover networks to seperate freqs

    I would basically be creating a notch filter or two to change the response of the output

    "They" say that a V30 has a mid spike that is annoying, or the 75 has a dipped midrange

    Well what if you had a switchable speaker level box that changed the eq curve to mimic these different speakers

    would it work or fail

    I have no answer to your question, but it sounds like an interesting idea!

    Maybe if you started with a G12K100 or something more neutral?

    first off- passive crossovers/filters suck up alot of power, therefore, changing your over all tone-
    I would think putting a 8/10 band graphic eq somewhere in line or in your loop would be a more workable solution.
