    Do new lightweight speaker cabinets with carbon fiber construction and lightweight speaker magnets sound as good as the older, heavy models?

    Cabinet design is an art and science of balancing compromises.
    But I haven't seen anyone ask: This cabinet is of minimum size and weight, so what was sacrificed to achieve that?

    Better design and better components allow good tone at lighter weights. I went from a 150+ Trace Elliot rig to something well under 50 pounds, with almost all the volume and tone.

    No, they don't.
    They sound better.

  6. Do not know about the carbon fiber ones but most newer cabs sound better than older ones.*

    *Depending on your tonal goals and preferences.

    But then, every cab sounds different from others regardless of make, model or year produced...

    Newer cabinets have much better speakers and many of them have much better construction than old school cabs. The speakers are more efficient, are built better, can handle more power, and produce lower frequencies. And they do all that in smaller, lighter enclosures.

    I’ve never played through carbon fiber cabinets, but my cabs are designed to be lightweight, handle ridiculous amounts of power, and sound great. What was sacrificed to achieve that? Budget was about the only thing. They’re not cheap.

    The claim isn’t that lightweight cabinets defy physics. On the contrary, the properly designed ones take advantage of physics far better than the old heavy cabinets ever did.

    I will put my little MarkBass CMD121P 12" up against my monster cab with 2 x 15" Altec 421s any day. Louder and cleaner - overall better sound. And I can carry the MB in one hand, my gig bag in the other.

    Not aware of cf options. Please share. Sound pricy.

    The main issue with super light cabs that i see is when the enclosure goes so light that they sacrifice stuff like internal bracing, and use a housing that is far too thin. However weight savings from neo magnets are win win as far as i know.

    an example of a cab that went too light is the orange 1x12’s. Mega light, no internal bracing, and lots of owners on forums asking how to stop amps from vibrating off the top. But results may vary… as the issue will be directly proportional to your volume.

    My rule of thumb is go for an in between weight. Generally best compromise. Too heavy is likely excessive, and mega light js likely giving something up (verify the internal bracing). And link together two smaller cabs that give you the end result you want. The total rig will weigh more, but each cab will be easier to move alone. So two 2x10 over a 4x10

    What does an amp vibrating off the top have to do with internal bracing and the cab being too light?

    The walls of the cab start resonating if it is not solid enough (strong walls and bracing help minimize this). Can vibrate your amp off the cab

    I don't know if it's a "sacrifice" but the materials that make the cabinet lighter require different skills than for typical cabinetry, and leads it to be more expensive. So time and cash are left on the altar.

    I was thinking that was just more of a side effect with lightweight cabs and amps. I mean, I have that with an Elf on top of an old Eden 4*10. Not a flaw, but a trade off. Doesn't mean the cab isn't solid, just means that it reacts differently, and physics.

    My Mesa Subway cabs sound better than any Trace Elliot, Ampeg, and Carvin cabs I’ve owned in the past.

    yes, it is all a tradeoff. Physics always wins. And you can have heavy cabs that vibrate amps everywhere and lighter well designed ones that do not. All comes down to design and material choices.

    All cabs will vibrate. But put a single brace in the middle of the longest length and it will take more to get that side vibrating at a high amplitude. Divide it’s length into thirds with two braces… even better. At a point it may be unneeded or unnecessary. All about volume/size.

    A fun test is to put some sand on an cab. Use a decibel metre on your phone to set a roughly constant volume. Compare! Never done it myself but i can guarantee you can do this to find where the bracing is in each cab without opening one.

    Knocking on them in different locations and listening is another way to find the bracing.

    image.jpg Even though I’m old and feeble, I like my heavy old “Joe’s” 15. It sounds as heavy as it is. It replaced a pair of SVT 15Es

    When it comes to bass cabinets I think the heavy ones pack a harder punch. I have a zero science but a bunch of pratlctical experience. It 'feels' to me like the heavier cabs 'hold their ground' better when moving air. Also, most players I like and see on tour still tote the big iron as do I.
