Am I crazy if I like MDF cab ????

Hey guys,

I'd like to share my recent discovery.

As far as cabs goes, I currently have a Marshall SL5 combo 1*12 (MDF, 50*50*25cm approx) and a Peavey 2*12 (poplar 18mm plywood, 71*45*29 cm).

The SL5 comes with a Vintage 30 and the Peavey features 1 Vintage 30 and 1 G12T-75.

Since the SL5 is made of MDF, I quickly decided in my mind that was crap and plugged for the most part into my Peavey cab made of poplar plywood.


The more I played on it and the more I was getting bugged by the Peavey cab because the bass were too boomy, not tight enough and the V30 (I can use each speaker individually in this cab) was lacking "punch" when playing heavy styles of music such as Metal.

Since I plugged again into my MDF combo Marshall speaker enclosure....and believe it or not, call me crazy, but the V30 sounds way better to me into this MDF cab, I mean it sounds "louder", "punchier" and way tighter in the bass, especially when I play palm muted thrash oriented stuffs.

I notice much of this difference for Hi Gain settings like I said. For classic rock, blues or hard rock, the Peavey cab is alright, plus I can convert it as an open back.

Long story short, I was surprised to hear the MDF 1*12 was "better" to my ears on heavy styles than the Poplar plywood 2*12 and I figured maybe a Birch cab would give me the stiffer, "deader" thing I like more about MDF with a little resonance as well that probably will give a better tone overall (yes I don't have any cabs made out of birch so far).

Maybe the Poplar, a lighter wood, is too resonant for me, and maybe that's the cause for some sound dispersation and lack of focus, I don't know.


As I don't want to put the Peavey cab in the trash just yet, and I need to add at least one other kind of speaker, a more vintage one, something from the Greenback family.


Do you think I'd be more pleased with the Peavey cab if I would use it for more vintage applications ? Like swapping the speakers for a Greenback and a G12H30 for exemple ?


That way I could put the G12T-75 in the MDF cab maybe, just for heavy stuffs and put the Vintage 30 into a proper Birch cab.

What do you guys think ?
 
Re: Am I crazy if I like MDF cab ????

The old 2x12 I used to have was solid birch (I think), & it was very midrange-oriented. The 4x10 cab I have now is MDF with solid pine bracing, and the sound is very balanced & powerful.
 
Re: Am I crazy if I like MDF cab ????

What happens when you wire the SL5 cab to the Peavey amp and wire the Peavey cab to the SL5 amp? Are you sure only the cabinet is what is making the difference?
 
Re: Am I crazy if I like MDF cab ????

Are we talking the same ohms load for each v30 when you play them?
 
Re: Am I crazy if I like MDF cab ????

Are we talking about the same size cabinets? No. Too many variables at play here.
That said, I have a large MDF 4x12 cabinet that sounds great (actually, it's got a ply baffle and back board now.) Also have a birch ply 4x12 that sounds great. Cant compare them because the dimensions are slightly different and they have different drivers. MDF biggest downsides may be durability and weight. If you like the MDF cab, all is good. You aren't "wrong" to do so. Just enjoy it.
 
Re: Am I crazy if I like MDF cab ????

The Peavey is just a cab.
When I compare both cabs, it's either with the SL5 or a 6505MH I have.

About the speaker load, they're differents. The V30 in the Peavey cab is 8 ohms and the V30 in the SL5 is 16 ohms (of course I adjust the right output on the amp).
 
Re: Am I crazy if I like MDF cab ????

You are comparing an open back MDF combo to a plywood 2X12, right? If so, it's apples to oranges, even with the same speaker. If the Peavey 2X12 is constructed decently, you may not want to throw it into the trash. I'm betting that if you had the same exact cabinet made of 18mm Birch ply, you'd be hard pressed to tell the difference between the two. There may be one, but all things equal except for the poplar versus birch ply, differences would be pretty subtle. Much larger difference would come from a different speaker. Or, open back versus closed.
 
Re: Am I crazy if I like MDF cab ????

I agree with the above statement that comparing the open back 1x12 combo to the 2x12 cab (I don't think you said if it was open or closed) isn't comparing apples to apples.

That said, I will say that, no, you aren't crazy for preferring a cab that happens to be MDF. Cabs and speakers and amps are all voiced differently, and entire industries exist to find the best combinations among them. Sometimes MDF just works. Case in point is my Marshall Haze 1x12 cheapo cab. It sounds great. Evidently the speaker in it was specially voiced to be warmer, and I totally hear it.

If it sounds good then you're good.

Most Hi-Fi cabs are laminated MDF. They are Great for sound, but they are lousy for living on the road.
If it is going to sit in your Studio/House.....MDF is fine, maybe even preferred by some....... If it is going to do much traveling, i think you will be happier with plywood.

About the speaker load, they're differents. The V30 in the Peavey cab is 8 ohms and the V30 in the SL5 is 16 ohms (of course I adjust the right output on the amp).

The same amp into a 16ohm x and into the same 8ohm x, properly adjusted for each speaker is still going to sound different from speaker to speaker. Ive done this myself a bunch in the same cab, with the same speaker and the difference is very noticable. So factor that in with the difference in cabs too.

True but the question was not about durability, just about his mental state.

Ahah !

Seriously, the Mdf cab in quesrion won't travel, it's really heavy for a 1*12, it actually weighs more than my 2*12.

The Marshall combo is not open back by the way.

Both are closed back, but convertible to open back (for the marshall it's the entire back board that you can remove, the Peavey 1/3 open).

I've found a used G12H30 for a nice price. I think I'll experiment first with putting the G12H30 with the V30 on the 2*12 and see how the G12T75 sounds in the MDF.
 
Re: Am I crazy if I like MDF cab ????

Quick calculation shows the Marshall is ~33% bigger "per speaker" so I'd say dimensions and speaker configuration are making a bigger difference than material at this point. But as others say, use what sounds best to you.
