I think I blew out a 15 through over-excursion

This is the easiest fix. Tell your guitar player to buy an attenuator to go between his head and cab. That should fix his volume issues.

Maybe, maybe not. Many players rely on over-driven speakers to get the tone they want, not just over-drive in the amp. It's pretty tough to overdrive four twelves without it being stupid loud. One twelve, not so bad.

For the practice volume problem he is describing it would be a suitable fix. Over-driving his bass speaker to keep up with the guitarist is what it sounds like he did. Pushed it to hard to long. Although I am not very knowledgable on the subject I have never heard of someone overdriving their speakers to achieve any sort of quality tone.

My band has a player with 2 huge cabs and a 3000w amp...and he refuses to leave them at home. Its pretty brutal when he turns up.

But he has the good sense to keep his volume in check, right? To quote Ben Parker, "With great power, comes great responsibility."

Follow up question.

With this sort of damage is it generally just the cone and voice coil, or can the magnet be damaged as well?

Normally it's the voice coil and cone.

I don’t think you can buy a Peavey driver re-cone kits - but you should be able to get replacement drivers directly from Peavey.

Actually, since the whole Black Widow series, Peavey has been pushing their "user-replaceable baskets" feature pretty hard.

BurningSkies has given many good advices. I think your guitarist needs to turn down. Also, you guys should check your EQs, if he's cranking up his bass knob, that could be why you have trouble hearing yourself. You guys should all slot yourselves in specific bands throughout the audible spectrum so that you're not clashing. You can also turn up your mids and turn down your lows a bit, I think it'd help you to hear yourself and reduce the sub-frequencies going to your cab.

Speaker distortion is something that you should listen for with your ears, not judged by numbers.

We talked the lead player in our band into leaving his JCM800 at home. He picked up a Jet City JCA20H dirt cheap and the rhythm player started using his bassman 50 and a 212. Sounds good and we don't have to mic the drums just for practice.

+1

Band practice should be as loud as needed for unmic'd drums.

To the OP. Either you ask your guitarist to change equipment or you are going pay the price (one way or another) of keeping up with him.

Ok cool, thanks Alex - I found it.

I understand that. When you say "over-drivin speaker" you imply pushing the speaker beyond its limitations which equate to farting sounds to me, hence the confusion. "breakup character" would describe pushing a speaker hard but not beyond it's limits.

I envisioned the op playing with a "light touch" with those settings and a string touching a pickup in error = no time to hear anything from the speakers, or ever again.

i have to laugh at the comments about guitarists and their 4x12s, confession time! i'm really a guitar player, with a 4x12, and a 2x12, since jumping to the low notes i have learned much, and to the comments aimed at guitards..... its mostly true, lol
the JCM800 head is a devastating guitar amp, they just arent controllable enough in the usual small gigs/rehearsal, a power break would help but the benefits are short lived IME, the "guitard" ends up cranking the amp even harder to get that "tone" only to choke the amp even more and then burn thro valves even quicker.

i have read BFM say that any guitarist never needs 4x12, when i 1st read this my thoughts were on the lines of "ahh what does he know", lol, but he is right, alot of my gigs on guitar have been done with a marshall 2x12, without even knowing about beaming i always used it on end, drivers vertically alligned, my logic for this orientation was 1. less stage space taken up, 2. raised the sound a foot closer to ear level, but knowing what i know now theres the 3rd reason, - better dispersion.

the band i played guitar in had a rhythm guitar player who used an old marshall JMP 100 watt head, this thing was the loudest amp i have ever come across, STUPID LOUD!, i'm not a fan of senseless noise, i like tone and dynamics,, even using a power brake he was overpowering my lead playing, most annoying,, so when i read posts about guitards i now just chuckle to myself and remind myself that most of the negative comments are quite simply TRUE!.

GET YOUR GUITARIST TO ENJOY MAKING MUSIC, NOT NOISE

Beyond its clean limit is driven. Beyond its mechanical limit is broken. Farting is breakup, just not of a pleasing character to you. Stranglers and Black Sabbath bass tone is knackered speakers on the early albums.

When rehearsing with the horn band, I take my Hartke LH 1000 and one LDS 2 x 10 cab. Lotsa amp for that little cab but, I keep my main volume low. We don't get that loud anyway but one ear is always listening to the cab...just in case.

I played guitar for a number of years and use a Mesa F-100. Beautiful amp with 2 12's, 100 or 60 watts. A lovely tone machine but as I got better, I realized half that Mesa would be more than adequate. But, I have turned that amp up. The clean channel cranked scares me more than the dirty channel. Brutally loud and no break up! Like industrial machinery clangin'.
