Hey folks, I have a Hartke Kickback (HS1200) that needs a new 12inch speaker. What would you guys recommend for a decent replacement speaker? I don't know too much about the bass world (amps and speakers), so any help would be appreciated. Also, if anyone has a HS1200 and has done a replacement - I am guessing that you have to remove the grill in front to replace the speaker? That is the only way I can see to get inside the cab. Is that correct? Thanks!
