Took the back off my DSL-40CR. PROBLEM SOLVED!!!
I have the same complaints about the DSL40 combo everyone else seems to have - fizzy highs at low volume and flubby bass at high volume.
Solutions online seem to be removing the C19 capacitor and replacing the stock speaker, but I don't like either option. I don't want to void the warranty by clipping capacitors, and I am too cheap to buy a new speaker.
To test if a new speaker would even do any good, I rigged the Celestion G12M-70 from my busted '86 5210 combo up to the DSL's 4 Ohm output and disconnected the stock speaker. (Thanks, Marshall, for the multiple ohm outputs!) It sounded sooo much smoother in the mids and highs, but the bottom end was gone. Not tightened up, just missing. I still liked the sound better than stock, though.
I figured taking the speaker out of the old semi-open-backed combo and putting it in the new closed-back combo might get back some of the lows while keeping the smooth mids and highs. Makes sense, right? After all, they say to put speakers in the corners if you need more bass. Physics or something. blah blah blah.
I started pulling the back off when the epiphany came (and a touch of laziness as well)...I thought "hey, if closed backs have more bass, let's listen to the flubby stock speaker with the back off to hear the difference before effing with the speaker swap."
Well, guess what? The flubby bass is gone!! Yes, the high is a bit fizzy at low volume but, you know, it's an effin Marshall. The fizz goes away when you turn it the master up.
So there you go: "How to mod a Marshall DSL40CR combo without voiding the warranty or spending money 101." Seriously, folks. Leave the capacitors alone and skip the speaker swaps. Just take the back off and turn up the volume. Problem solved!
