I sure hope I never meet the Polk engineer that decided it was a good idea to put the little plastic plugs in the speaker binding posts in a dark alley, because only one of us will be coming out and it won't be him!!! I have never spent such a frustrating afternoon trying to connect my new to me RTi38's.
I bought a pair of RTi38's from forum member GZ who lives in Southern Wisconsin. We decided to meet about 1/2 way from where I live in Northern IL for the hand off. The drive was easy and the location (a DMV office parking lot right off the interstate) was easy to get to. Met Gary talked a little bit about the Polks we owned and I loaded them up and headed home. Couldn't listen to them right away since I stopped into work to catch up on some things, etc.
Get home and remove them from the original box and packing and they are literally brand spanking new! Can't find a mark on on the real wood veneer cabinets nor a snag on either of the grills. It's obvious the previous owner used bare wire with these speakers because the binding post plugs were still in place. They sit flush with the binding nuts and there in lies my frustrating afternoon.
How in the hell do you get these things out? The binding post nuts have a point where they stop as they unscrewed so you can't remove the nut entirely, well that doesn't help at all. Since the caps fit flush with the nuts, it is impossible to get even the smallest flat blade screwdriver under them to pop them out. The fit is too snug to get what little finger nail I have under them to pull them out. WTF!!!!!!
So with my smallest flat blade screw driver I start "digging" at them to get them out. One speaker I was able to finally get the corner of the screwdriver under one small part of the cap. Of course this was after marring up the plastic binding nuts pretty good, but success I get them out after about 20 minutes fiddling with them. Not at all happy about the marks I had to make on the plastic nuts with the screwdriver.
I start on the 2nd speaker and after struggling for 10 minutes the top of the plastic plug breaks off leaving the post of the cap in the binding post. SH*T!!!! Now what, I have banana plugs and now WTH do I do? I start on the second binding post, working more carefully, snap.........breaks the cap off on this one too leaving the post of the cap in the binding post. Double SH*T!!! At this point I am extremely frustrated.
I proceed to take the terminal cup out and of course the binding post is closed on the opposite end, the hole doesn't go all the through. My thought was I could get in behind the binding post and push the broken post out from the opposite side. Nope, now way, no how. I am extremely pissed at Polk now for doing such a stupid thing as putting caps in that are impossible to get out. So I unscrew the actual binding posts from the PCB and terminal cup and barely am able to use a pair of miniature needle nose pliers to grab a small part of the broken cap post sticking above the hole in the binding post.........success!!! YES!!!!
The second one didn't go that way. I ended up having to drill out the plastic post the best I could to be able to use banana plugs. Screwed the terminals back into the PCB and binding post cup, etc. Finally was able to listen to my new to me RTi38's.
I will need to order a new binding post because there are still bits of plastic in the positive post of one of the speakers.
Why did they put these in the holes to begin with? Why did they poorly design them and make them impossible to get out?
Next time I'm getting a tooth pick and putting a dab of super glue on the end and gluing it to the cap and using the tooth pick as a handle to pull them straight out.
Thanks for letting me vent.
