Why change all four? The two speakers on the right side are fine to my knowledge.

Sorry, Denmark.

Regarding wattage, is it essential to stick to 150 watts per speaker, or is there some flexibility?

In the meantime, if I were to switch out the two speakers (the broken one and the one that the technician incorrectly installed), what would then be the correct ohm to buy? I live in Northern Europe, so I don't have access to US markets.

I'm truly appreciative of your prompt responses! Currently, the cabinet isn't at my place, it's situated at our studio. But I'll swing by, give some of your ideas a try, and gather some more info so I can answer your questions better. The original speaker placed above the new one has given out. I'm not sure what the tape is doing there, but I'll get back to you on that one. That's a good point, I wish I had thought of it earlier. I currently don't own a multimeter, but I will acquire one soon and then share the findings with you here. Fortunately I use a GK1001RB which is solid state and can take 4 and 8 ohms.

Hello wizards, As an absolute beginner to cabinet repair and musical equipment maintenance, I'm venturing into uncharted waters here, so please bear with me. I need advice on removing glued speakers and on identifying suitable replacement speakers. I am the proud owner of an exceptional Mesa Boogie PH410, which I believe is top-notch. However, following our recent performance, I suspect that one of the four speakers has blown. It's begun to sound noticeably distorted compared to the others, and it also seems to vibrate more intensively. I purchased it second-hand, and the previous owner had one of the speakers replaced by a professional repair technician who has experience with this specific model. However, he is currently unable to service it within an acceptable timeline, hence he suggested that I simply purchase the same type of speaker he had installed earlier. When I tried removing the faulty speaker, I found it firmly glued in place. Can anyone suggest a reliable method to handle this? I own a heat gun; would that be an appropriate tool to use in this situation? To assist with identifying the right replacement, I've attached a photo of the speaker that was recently replaced. To my limited understanding, the speaker indicates 4ohms. But if the total cabinet impedance is 8ohms, shouldn't each speaker, when wired in parallel, be 32ohms? Interestingly, on the Mesa Boogie's official website, it's mentioned that the original PH custom Eminence speakers are no longer in production. They recommend using Eminence Legend CA10 as a suitable replacement. However, I am unsure of the impedance I should opt for. Can anyone provide guidance on this? https://store.mesaboogie.com/products/speaker-10-eminence-legend-ca10-8-200-watt-8-ohm-1.html The original speakers don't have any discernible markings on them. I sincerely hope some of you can provide me with some guidance. My apologies for the lengthy narrative, but I am genuinely in need of assistance. Thank you.

I guess you could get the mounting ring from Chris turner. I recently bought a pair of SEP multicoils from him and I got the mounting rings along with them. It seems like you could fit any MM style pickup in it, but I don't know if slot depth could become a problem. But I could be very wrong..

Following this whole adventure is incredibly addictive. I'm really curious about what will be the factor that pulls out the 600k and 800k spikes on the spectrum.
