Put holes in your cab?

So after a year of fcuking around with the shitty castors on my Framus Dragon cab I've decided that I'm just going to invest in a better castor set as found on Mesa cabs. The only thing is that the castors on the cab atm have a system where there are 4 screw holes and a larger hole for the castors to slot into, where the Mesa ones only have two screws and no hole. This means that I could be left with a bunch of holes in my cab where the sound would be able to escape.
What would be the best thing to do once or before the new castors are in place- fill the holes with silicon/ liquid nails type products, or just open the cab up and cover the holes from the inside with a thin sheet of wood?
Or shoudl I just leave he holes as they are and hope it doesn't effect the sound too much?

:erk:
 
I'd cover them with a piece of wood from the inside - just to make shure it is really sealed. Maybe even put silicon around the piece of wood...
 
What's the effect of having holes in a cab where air can escape?

From the limited research I've done, I understood it as this-
The more airtight a cab is, the more forward projection it should have. I'm also pretty sure that the quality of seals would effect the sound in the same way as quality of woods used (but maybe to a lesser extent).

In a general speaker enclosure, "ports" (holes put in for a reason) usually play around with the low frequencies.
 
Cover the holes with the Mesa casters. The tolex and metal screwed tightly together should be enough to seal the air in.

Good point.

I will keep this one in mind, because as soon as I read it I relised that I wouldn't have to use a huge piece of wood (which for some reason is what I envisioned).


Woot! Problem solved! Fucking Framus castors can now piss the hell off.

Just out of interest, what exactly did you do?
 
I'm assuming you're refering to the "problem soved" bit, but I'll give you the rundown.
Thus far, used the cab in a normal fassion IMO. I only gig about once a month (ok, about 9 times a year). The piece that goes into the cab and holds the caster in place broke on more than one occasion.
As far as fixing it goes, I haven't done anything yet, I've just figured out how to fix it without it being a big deal thanks to the replies. The wheels are now in motion, I've contacted a local ditro for prices and availability, so I'll get them asap.
 
Yeah, I was just wondering what you were thinking of doing to cover the holes lol, DSS3's method, or using some wood/silicon to seal the holes?
 
Haha, probably both :p Just to be extra sure I guess. I wasn't sure about gonig the wood/ silicon route, but I guess it would make it tighter than it is now, and there are 4 screw holes as well as the main hole in each corner. It wouldn't be a problem if the new casters had the same alignment of screws.
 
ive played alot of shows, and i get sick of even having to truck my mesa 4x12's around on casters. ive decided im going to eliminate the over priced caster issue all together, im going to just throw some offroad skateboard trucks and wheels on the fuckers and keep the trucks real tight so they wont flex when i put my heads/rack shit on top.

haha, i wonder if its even possible. im sure that the look would take off in the fratboy/numetal scene :puke:

*leaps from lifted truck, removes lifted cab, pounds a can of budlight and pushmoshes around parking lot with other bros to sevendust*
 
Guys, small screw holes aren't going to affect 'forward projection' or the 'low end' of the cab. It's when you start getting into bigger holes is where the low freq tunning comes into play. They only thing you might hear is a slight whistle coming from the screw holes, but you would have to be right near it to hear it, and the sound from the speaker would most definitely be louder than it.
