I've been using my Promethean as a monitor with PA support. After our last gig it has developed a nasty buzzing sound, as if the speaker had been slashed with a knife. I'm going to open it up and look around and see if there's something out of place, but if the speaker needs replacing then could anyone recommend a good 10" speaker that 300 watts @ 4 ohms. Thanks.

Problem solved. Took the front grill off, no tears on the speaker cone. Removed the speaker, all wires and contacts were good. Put the speaker back in, tighten down the screws, plugged it in, and it sounded fine again, no buzzing. Had to have been a loose screw causing the buzzing. Glad it was a simple fix, for a while there I thought I was going to have to spend money on a new speaker, or even a new amp. I'm a happy camper again!

I just bought a second P3110 and am selling my acoustic amp. The great part is, I can stack two together for my bass rig! Acoustic guitar / bass, both sound awesome. No need for an acoustic amp anymore.

Well, the buzzing of the speaker came back, and there was no stopping it. So I went ahead and replaced it with an Eminence CA-10 Speaker, 200 watts, 8 ohms. Sounds fantastic, plenty loud enough to be heard, and since the amp is a monitor for me it doesn't have to be insanely loud.

Good to know! Don't you miss the tweeter and how does it affect impedance since now you are using one speaker instead of the Ibanez stacked two?

Reviving this thread after some time. My p3110 speaker ripped and I want to replace it with an Eminance 200w 8 ohms I have laying around. But would it be a problem if the amp feeds 4 ohms into an 8 ohm speaker (wich is what I understand is what happens, and the original speaker would split it in two times 8 ohms with the double coil). And could I still connect an 8 ohm ext cab? Please help before I blow things up.

There is something strange with the P3110. it actually has two speakers joined together as a coaxial speaker. One is the woofer and one is the tweeter, all in one frame. Be careful with your Ohms.

And JCW308, I saw you were using 2 3110's stacked. How does it sound and how do you connect them? I can get me a second 31110 cheap and was thinking about this option too.

The impedance of the tweeter doesn't factor into the calculation of nominal impedance due to the crossover present.

The other issue is how the cabinet is tuned and if it's a good match for your driver.

Just be careful. The tweeter actually was a factor, see Ibanez documentation. It is not the standard configuration we all thought it was. Someone already did this and wound up blowing their amp up. I no longer have mine, they are log gone.

Thank you, that's what I thought.

I know, my Eminence will work in this cabinet, I have to change the port length a bit. But my question still is, can my 8 ohm speaker handle the 4 ohm fed by the amp?

What amp are you using?

The original cabinet is 8 ohms, you are replacing the original driver with 8 ohms, so if the original cabinet worked with your amp, there's no reason why the replacement wouldn't work as well. Am I missing something that you are not disclosing?

It will work fine but you'll get only get around 150w out of the amp. The head is designed to run 2 speakers at 8ohm each and will be happy enough to see just one.

How are these Ibanez amps? Have considered getting. Ibanez seems to me to make quality merchandise. More interested in tones, not worried about power levels.

I have the 5110. and I like the size and weight. For those times where it's big enough it's been great to own. The tones are - to me - very basic, clean and uncolored. The 3110's aren't much different. The EQ has enough range to get lots of different tones much like a Peavey or other inexpensive SS amps. Nothing to complain about but nothing to write home about.

It would be helpful if you asked this specific question directly, and if English is not your primary language and you are translating, let us know so that we don't mis-understand what you post.
