    I don't think you will! A particle back panel on the other hand...

    For now, I will stick to the particle one in my 4x12.

    Yesterday I brought it over to band rehearsal. Sounded great with my 20w JMP, although the single G12H30 is kinda overpowering the G12M25. Guess I'll be looking for a similar Blackback G12M25 75hz to replace it with...

    I can't be certain but I think the MX series cabs are all MDF.

    @What? is absolutely correct and right on the money about the random mixing up of the names, of some very different products!

    OSB

    FWIW, many 8x10 Ampeg SVT "refrigerator" cabs are actually made from OSB!

    I'll Offer No Opinion!

    I had no idea about that. Whatever, I guess. Those are my favorite sounding bass cabs ever. Moving one around regularly is a bitch though.

    Not likely. MDF is heavy (higher shipping costs), relatively expensive (compared to particle board), and hard on saw blades (higher tool costs). I don't see Marshall using it for cheap cabs.

    Chip board and MDF are two completely different. This is Chip board.

    No that's OSB.

    But you're right MDF and Chip board are two completely different materials.

    My drummer used to have a small 2x12 that was home made out of particle board (not MDF). It was the shittiest piece of shit. The fucking thing was coming apart.

    Yeah, that pic could go either way OSB or Chip, I've seen sheets like this called both.

    There are actually three types of so called "Particle" or "Chip" Boards which both these are really generic terms. One is OSB (looks like chips), one is MDF and one is Particle Board. They are all made from chopped up would. The differences are the size of the particles, glue, etc. I learned this a few years back when I called on a large MFG in my Sales Territory that mfg'd all three types.

    This article basically sums it up including plywood:

    MDF is very common in audiophile home speakers.. it is dense, has much less resonance than plywood or particle board and is easy to work with tools such as routers.

    all other things being equal, for guitar applications, with two identical cabs where one is made of MDF and one made of plywood/particle board, the MDF cab will sound more accurate (true to the source) while the plywood/particle board may well sound "better" to some or all... Note that in home audio applications, accurate IS better, but in guitar applications as we know just better is better.

    Then there is particle core ply which is wood veneer with partical board core. This is tough to tell unless you can see a cut edge

    @Sir Don is correct @What?, all the MX cabs are made of MDF. Also @Mystic38 nailed it regarding MDF, it is a neutral material sonically, and it’s widely used in the high-fi industry. Also my friend @pedecamp is correct with his comments on MDF.

    Although if I was a gigging musician, I would definitely want a plywood cabinet. It’s lighter, and more resistant to moisture than MDF. But with me being an at home player MDF is a solid choice, especially if you’re on a budget.

    Here’s a good example,…

    When I was looking for a 1-12 Marshall cab, I did some research and price checking. The Studio 1-12 cabinet is made of plywood and has a Celestion V-Type, It is $750.

    A 1-12 Marshall MX112R is made of MDF and it comes with a Celestion 70/80 speaker for $299. Now most people do not love the 70/80 speakers, and would replace it with something else.

    I bought the MX112R for $299, and I changed out the 70/80 with a G12M-65, that was $135 att, for a total cost of $434.

    Of course a made in the UK cabinet will be more expensive than a cab made in Vietnam, no doubt and I know it.

    The bottom line as far as cost is concerned is not even close. $750 compared to less than $450 for a 1-12 cabinet. Keeping in mind the $450 cab has a Creamback in it at that price.

    Just my :2c:

    The Shit Plastic JCM8 handles are a constant sources of rattle, and must be upgraded to the metal sealed type. Costly but worth it. The sound post must be secured. many have sold their cabinet, thinking a speaker was blown, due to sound post rattle against back baffle.

    ....but you guys know all of this....: )
