After intensive research and invaluable comments from Tung and Tig I decided on an Eminence Delta 12A Speaker for the cab. The thing is, its rated at W RMS, peak, which flies in the face of all conventional wisdom. It also seems that this speaker will not color the sound of an amp and has a 'better' sound than the EVM12 L which the speaker enclosure was designed for. I need to figure out how to "break" in a speaker with a 9 volt battery. On to the pics! Internal bracing finished, including port area.

Cleaned up a little and from another angle. You can't see it very well. July 7th, , PM 5. Originally Posted by Monkus. From my googling, this seems to be ideal replacement for the EVM12L.

Are all speakers broke-in is some fashion or another e. July 7th, , PM 8. Stereo speakers are a different animal. They have synthetic cones and surrounds, which do not loosen up over time like the paper cones in guitar speakers. Stereo speakers are typically played clean with no distortion in the signal, their purpose is to reproduce recorded sound.

Guitar speakers generate music and there can be lots of harmonic distortion in the signal. July 7th, , PM 9. Originally Posted by Ch0jin. Or as I like to say "Hi-Fi speakers are about reproducing the sound.

Guitar speakers are about creating the sound" I've never really tried to break any in myself though. The speakers in my 4x12 were made in the 60's so I'm assuming they were broken in long before I acquired them. July 7th, , PM From what I've read so far, it depends. Some speakers might have a brittle edge to them because of the components, stiffness as a result of the manufacturing process or any amount of other reasons. As the cone and coil moves, they relax within tolerances over time. Some might not.

I guess the questions are: Do you want the broken in tone faster, or do you want to enjoy the entire breaking in process of the new speaker? Some more experienced fretters may chime in on this.

The article from PG linked above explains it really well. Personally, I would like the broken in tone of the speaker as fast as I can so I can evaluate my amp easily. May not be necessary but might be worth looking into.

July 8th, , AM Breaking in makes sense, I just had never heard of it before Thanks for the explanation guys! BTW, Monkus..
