    I bought a Peavey 112 Extention cab
    for my Classic 30 combo.

    The description says it has a Blue Marvel speaker,
    but to my ears it sounds totaly different than the Blue Marvel in the combo.
    Less heighs. Also it's not as loud as the combo speaker when both are connected to the combo.

    No i've read on some guitar forums, that it's not a Blue Marvel but a Valveking Speaker.

    What's the truth?

    So i mailed to the Peavey Service, this is the answer:

    Hello,

    The 112 Extension speaker wasn't actually intended to be used as a match with a Classic amplifier.
    There are other Classic extension cabinets ( old & new ) .
    The original 112 Extension speaker was called a Vypyr 112 Extension speaker with " Blue marvel " speaker in it.
    But this wasn't the same Blue Marvel that was in the Classic 30.
    They did change the name of this to a Peavey 112 Extension Cab and after a while
    the speaker in it was changed to a Valveking speaker.

    Thanks,
    Peavey Customer Service





    So they sell a cab which says "Blue Marvel" but it's a "Valveking".
    I'm not amused.

    I thought "Blue Marvel" was a generic term Peavey used, just to signify the speaker was designed for the amp? I think the Classic 30 has a specific voice, and needs a complimentary speaker by selection - you'll not only need to find a Blue Marvel, but the *right* Blue Marvel, or other speaker with the right response, efficiency, etc. I'm sure there are some threads here that offer some recommendations for Classic 30 speakers.

    Your volume drop with the extension, is probably due to a series extension circuit. In series, your 8 ohm speaker and 8 ohm extension cab combine for only 16 ohm load, which can drop the overall volume, if the extension speaker is equal or lower efficiency. I use an extension to get my combo closer to chest level, and have to run it hotter to offset the volume loss.

    So i need the same Blue Marvel like in my Combo or something different.

    The internal speaker and the cab speaker are both 16 Ohm, so i thought they have to be equal in loudness - but i also thought it's a Blue Marvel :)

    The volume drop is only on the extension cab, so i think it's a speaker efficiency thing.

    Now is a good time to look for a matching pair of Jensen, Weber, Celestion, N.E.Other speakers rather than playing mix'n'match. It will, of course, open a whole new can of worms.

    They're not bad, but to mash Star Wars, it isn't the speaker you're looking for. They're almost a Hi-Fi speaker. Their fairly characterless nature lends itself very well to solid state and modellers and players of pedal boards. They take a heck of a long time to smooth out, and when they do, they're innocuous enough. Their nature may not sit well with what you have currently. They're also installed in a fair few combos as 'Celestion V-Type'
    A lot of owners trade them out for speakers with character, speakers with a softer treble or less well controlled low end. The Internet has many folk acting as detractors of them, which does push the price down. Most detractors are echo chambers and have never cranked the Seventy-80 after it's been bedded in.

    I own a couple of them, and can't be bothered changing them out. Nor would I actively seek additional ones.

    As Douglas Adams would put it, 'Mostly Harmless', which damns with faint praise.

    I wouldn't, unless it was for a pair.

    A guy gave me the tip to swap the speakers:
    - the Valveking in the combo (less harsh)
    - the Blue Marvel in the cab not so much bass in the closed back

    I just pulled the original Blue Marvel from my 90's C30 a few weeks ago and put a C-Rex in it. I couldn't be happier! Physically, nothing wrong with the Blue Marvel, just too high-end spiky for my liking. So, the Blue Marvel sits in a box, ready to go back in the amp should I ever decide to sell it someday.

    I don't want to buy another cab, too expensive at the moment.
    Used speaker is cheaper.

    But Thanks

    I'm not a fan of the 70/80 they sound farty and lifeless to me for the most part. They come installed in a lot of amps because they are cheap. It is a neutral sounding speaker. I have heard it in a few modeling amps where it was ok.
    Speakers are such a mixed bag and really as personal to your sound as the guitar you play .... therefore it is hard to recommend one. I really wasn't all that fond of the Blue Marvel either but over the years my opinion of it has changed to liking it. I kind of like the C. Rex for the C30 myself. YMMV.

    I'm pretty sure my tweed 112 extension cab came with a 16Ω Sheffield speaker in it. that was in the mid-90s.

    I have a couple, they come stock in a few Blackstar amps

    They are fine at low volumes but once I start feeding them some power they seem a bit harsh after a few minutes. They wear my ears out. Ive heard from a few people as well.They will be switched out over time

    Strange phenomenon:

    After a Gig last Week (where i had to crank the Combo and teh extension cab),
    the extension cab sounds totaly different. Louder and brighter.

    Is it possible that the speaker needed the high volume to break in?
