    (Nice grammar in the subject line, eh?)
    Okay, as promised, the pix of the relocation of the port hole on the rear panel of the SunOnes:
    Photo 1 : I use the original port hole to trace out the diameter I will need for the replacement MDF plugs.
    Photo 2 : Here's one of the plugs routed out by my trusty router and circle jig.
    Photo 3 : This is the test fit of the MDF plug into the original port hole. Pretty darn close fit!
    Photo 4 : After careful measuring of where the port hole needed to be in relation to the compartment behind tweeter, I draw the required hole needed for the new port location on the rear panel, and drill in the require pivot hole for the circle jig. This is very important to get right.
    Photo 5 : This is the plywood panel I'll be using to seal out the hole, and the glued areas for it. This will insure no airleaks through the old port hole.
    Photo 7 : Just a bit of weight placed on the glued plywood to cover up the hole while the glue dries.
    Photo 8 : More glue in the old port hole is applied now that the plywood's glue is dry.
    Photo 9 : The MDF plug is now glued in place.
    Photo 10 : To fill in the minor gaps between the plugs and the rest of the rear panel, I slap on some wood filler.
    Photo 11 : Once the wood filler dries, I use the orbital power sander to smooth out the surface.
    Photo 12 : After some power sanding, you can barely feel any difference in the surface where the plugs mate with the panel. It's now pretty smooth. Once I put on a few coats of primer and sand it, I doubt anyone would ever be able to tell there was a hole there in the first place.
    Photo 13 : Here's a shot of the inside part of the rear panel with the glued plywood panels in place.
    Photo 14 : I test out the fit for the ports in the new holes in this shot.
    Photo 15 : My cats inspect my handywork. My careful placement of that new port hole pays off as the rear panel now fits perfectly on the backside of the speaker. I'm done.

    Good recovery Patrick. BTW, when a port is directly behind a driver, what exactly are the effects in terms of sound/performance???

    Put it close to a wall, and it'll sound "weird" maybe a bit echoey.
