Dsl 40c Buzzing/fuzzy Sound Blown Speaker?

Yes i can definitely hear a rub. i really hope a new speaker solves the problem

It should take care of the problem for now, but there's no way to be sure if it's a faulty driver or something else. When heat builds up in a driver faster than it can dissipate, it's usually bad news. The louder you play, the longer you play loud, and the greater the driver excursion, the greater the risk of damage. Of course, all these things can exacerbate a latent defect in a speaker.

I once had a British-made G12-T75 develop a rub and an audible buzzing. No problems with any of the other three. I replaced the bad one with a Chinese driver, which was what was available. No problems since.

BY "driver" do you mean the first preamp tube? (sorry im not aware of the technical lingo) i read that preamp tube problems are more apparent on the overdrive channel

"Driver" = "speaker"

Thanks, so playing loud for a long time is bad for speakers! how loud should i play? i am used to playing at a very high volume even at home

It's very hard to pinpoint exactly what's safe and what's not, for two main reasons: One, we can't see inside the speaker to know what's going on with the voicecoil and magnet, and we certainly don't have a thermometer inside the speaker to know what the voicecoil temperature is. Second, we guitarists are likely to be playing with intentional distortion that can mask some of the trouble signs.

Audible trouble signs can be distortion from a clean amp with high headroom, any strange mechanical noise like a throbbing, popping, clanging, or rat-a-tat-tat, for example, or basically anything you're not expecting to hear at that moment.

If you smell something from your amp, you've probably gone too far.

Yes, don't let the smoke out of the wires. That's always bad.

Good guitar speakers are tough mothers but you don't want a cranked JTM 45 playing through a single 25 watt Greenback for example. There was/is a rule of thumb and I'm not sure I remember it exactly but it's something like taking your amps rated power and doubling it and then using a speaker or speakers that are rated for that amount of power. So, a 40 watt amp into an 80 watt (or more) rated speaker, or two 40 watt (or more) rated speakers and you should be ok. Amps are usually rated for the amount of clean power they can deliver based on some maximum distortion figure, 2% or 5% or something like that. That same amp cranked can be outputting much higher distortion with a nasty looking square waveform with peaks that may be double or more the clean power rating. That's why that rule of thumb exists regarding the speakers power rating being double that of the amps power rating.
