Considering the power of the JP-2C you have several choices for speakers that are rated for 150W or more. What speaker I did find to be ideal at the moment was the Organic Timbre Rhapsody G12F. Yes it is a re-engineered EV speaker but does not sound the same or is not flat in frequency response. I have bought one and loaded it into the Mark V combo but had to find out how the JP-2C would sound though it. That was amazing. As close as I can get to the Mesa Vertical 212 but with a single speaker. I have an OS Recto 412 loaded with EV black labels I may end up pulling two of them and replace them with the OTR speaker. The combined tone using both EV and the OTR is awesome. Bottom end of both speakers is about the same, there is a bit more roll off on the high end frequency with the OTR but is there with the EV and the mids are accentuated with the OTR but not the EV. I have a 1x12 extension cab with an EV in it so I can hear the combined results. Too bad they do not offer the speaker in a 16 ohm voice coil as I would like to run two in a 2x12 cab. At least the JP-2C can run both 16 ohm or 4 ohm so If I get pair of speakers it will be wired as a 4 ohm or 16.
What I really love about the OTR is the tone and response on the clean channel. It explodes quite well into mayhem on the higher gain channels without sounding honkey or thin (lacking the mids). I was also considering picking up a used 412 cab and get 4 more OTR speakers. Either mix the EV in both or just run one cab with EV only and the other with the OTR. So tempting.
If Mesa were ever to plan on a combo version of the JP-2C the OTR speaker would be ideal.
