Speaker recommendations?? Halp!

Hi all, I have a mint vintage JC-50 all stock. It sounds a bit flat and would like to swap out the speaker. The stock speaker just sounds a little flat. Just not sure which speaker to buy. I am looking for a real super clean sparkly tone. At first I was thinking just replace it with a stock Roland JC-120 8ohm speaker but who I got it from seems to have a lot of JC's and says the Altec Lansing 417H would sound best. Any onions out there? Thanks guys.

Forget it. I put in a V30. Sounds awesome.

hey, I sent a PM, but not sure if it got delivered...
