And I always thought those grill-like slots on the DK cab was where the speakers was ?
Well, if you want the worst of sound quality, not making a hole is your best option.
You will need to turn up the volume of the amp up needlesly. And you can forget about high frequencies.
Fine if you want to keep to an "original" 80's sound of cabs.
On the other side, if you want best sound quality (maybe even use your cab as a jukebox ?) you will need to cut holes.
I did this but I'd like to add something: be sure the hole is large enough so that the conus of the speaker will not touch the wood or mdf of your cab when moving. This is unlikely to happen with small speakers, but if you use serious bass units and drive up the volume this can happen and causes a distored sound and is also bad for your speaker. This happened to me, I too thought that my grills would cover up my bad sawing, but didn't expect this to happen...so now I gotta make my holes a bit bigger, which will be a not so nice job....
Take a look at my work at:
