Members guitarbilly74 Posted March 23, 2012 Members Share Posted March 23, 2012 So I was looking at this picture: And I noticed my MF cab does not have that center piece. I don't know if it was removed or the MF280 is different (the above pic is the MF400). Anyway, what's the purpose of having that piece in the middle? I guess it would be easy enough to add one, if it makes a difference. Link to comment Share on other sites More sharing options...
Members Yarbicus Posted March 23, 2012 Members Share Posted March 23, 2012 It looks kinda like a bar graph. Link to comment Share on other sites More sharing options...

Members Marc G Posted March 23, 2012 Members Share Posted March 23, 2012 it couples the front baffle to the back of the cab.. from what I understand it helps transfer the vibration from the speakers... more resonant.. I could be wrong though... Link to comment Share on other sites More sharing options...
Members isvoid Posted March 23, 2012 Members Share Posted March 23, 2012 what's the purpose of having that piece in the middle? the way my brain logic works suggests it's for stabilization / stiffness of the back panel, making the sound tighter / less "loose" Link to comment Share on other sites More sharing options...
Members LA-Ü-RA Posted March 23, 2012 Members Share Posted March 23, 2012 My understanding is that it mainly functions as a brace for the back. Sometimes they are removed because the back of the cab can vibrate against the brace when playing. I have 2 cabs that were built without them. The guy who built them said he always removed that brace from his old Marshall's because of the issue he had with vibration. Link to comment Share on other sites More sharing options...
Members redeye5 Posted March 23, 2012 Members Share Posted March 23, 2012 for ultimate stiffness you can even screw the back panel into the bracer.. I actually had to do that on my Mesa Recto cab because it would vibrate and I could hear it. and yeah ^^ I prefer screwing through the back panel instead of removing the bracer Link to comment Share on other sites More sharing options...

Well, I don't have a problem with the back not being stable enough, so I will just leave as is. Link to comment Share on other sites More sharing options...

Members redeye5 Posted March 23, 2012 Members Share Posted March 23, 2012 true but it is one of my problems, {censored}ing mesa recto cabs are not stiff, more like ED cabs:cop: Link to comment Share on other sites More sharing options...
Members LA-Ü-RA Posted March 23, 2012 Members Share Posted March 23, 2012 Here is a pic of one of mine when I first got it. I removed that crappy wiring and ran it with better copper wire. Link to comment Share on other sites More sharing options...

Members Warhorse Posted March 23, 2012 Members Share Posted March 23, 2012 My Mashall cab had the vibration problem, so i just glued a piece of stiff thin foam on the end of the block. Problem solved. Link to comment Share on other sites More sharing options...
Members 100 watt Posted March 23, 2012 Members Share Posted March 23, 2012 My MF280B has the brace. Im not sure if the angled MF cabs have them or not. Ive only been inside the B cabs. (cant see your pic. cant tell what it is) You can solve the vibration / rattle with a thin piece of foam or rubber stapled or glued to the rear baffle where the brace goes up against it. Mine has a piece of an inner tube stapled to it. Problem solved While your inside it, make sure the front baffle screws are actually tight. Ive found that alot of Marshall cabs from the past 20 years have loose baffle screws. Link to comment Share on other sites More sharing options...

And yeah I checked the front baffle screws the first time I opened it. Some of them were loose indeed. Link to comment Share on other sites More sharing options...
Members 100 watt Posted March 23, 2012 Members Share Posted March 23, 2012 yeah. I just mentioned the vibration thing in case you decided to replace it. Link to comment Share on other sites More sharing options...

Members 100 watt Posted March 23, 2012 Members Share Posted March 23, 2012 well I was thinking about it but from what I'm reading here, I guess I can just leave it alone My Orange 4x12 didnt have a center brace & sounded fine. I wouldnt worry about it. Hell..my MF cab only has 2 speakers (the top 2 holes are blocked off) and its sounds thicker & heavier than my other "tall" 4x12. Whatever works..

Funny you mentioned, because I was thinking of doing the exact same thing but in a "" pattern. Have you tried to do that? Link to comment Share on other sites More sharing options...
Members sleewell Posted March 23, 2012 Members Share Posted March 23, 2012 i can't believe you guys still lug 412s around, they are so heavy. i just bought a 212 but even that is a little too heavy, maybe i should get a 112?? Link to comment Share on other sites More sharing options...

I havent tried it yet, but thought about doing it. Go to Lowes or Home Depot. In the lawn & garden section, they have these things that look like giant drink coasters. They're cork on one side, and some kind of wood on the other. They make a size thats perfect for blocking off a speaker hole. Just mark the screw holes w a sharpie & drill the holes for the screws & wa-la. I ended up painting mine black so you couldnt tell they were in there. The 2 Eminence Delta LF's in the already oversize cab sound MASSIVE. Im eventually gonna put another jack in the back & another pair of 12's, so I can run 2 heads into one cabinet.

Im a bigger guy, so it doesnt bother me. Plus I drive a full size truck (insert dick size jokes) so no probs with moving 'em. Im old school. I just like a half stack (or 2) Link to comment Share on other sites More sharing options...

Members 100 watt Posted March 23, 2012 Members Share Posted March 23, 2012 Yeah. It's just what I like. I cant count how many times Ive heard "Do you REALLY need that much amp? Why have all that, when you can just use a __________ . ". There's just something about a head & 4x12 & a couple pedals Link to comment Share on other sites More sharing options...
