3k array and scoops on 242s - removal

3k array and scoops on 242s - removal
Hi all,

I have a small scratch on one of my scoops of my 242s and fancy giving it a satin black respray.

Is removing the 3k array as simple as it looks? All the bolts and is slides out / unplugs? Or is it not quite as it seems?

Then -is it possible to remove the scoop from here or is it fixed to the cabinet somehow?

Philbo - I am guessing you hold the key to this Wink

Thanks!

RE: 3k array and scoops on 242s - removal
If it's the same as a 212 them yes, it's pretty simple. Undo the bolts, keep holding it to make sure it doesn't fall on the floor, then pull it away from the speaker. It's plugged into a large-ish connector behind which maybe tight or may be loose enough such that it would fall on the floor unsupported. You can lever it slightly as you can get a bit of a grip from the lip of the bottom of the unit but it really needs to come out directly away from the speaker and not at an angle.

Don't bother cleaning the contacts before putting it back on as most contact cleaners can leave a residue and affect the sound badly.

Putting it on again ... Do not over tighten! Ideally use as fine torquedriver. You probably don't want to torque it much over 1NM as it would risk pulling the capture nuts out of the speaker which you really do not want to do. TIghter is not better. There's probably some recommendations on here for torques but 0.8-1.0 NM is about right. This is really only finger-tight.

As for disassembling the unit for painting - I don't think you can.

Personally (because it would scare me) I would leave and use one of the fine "pens" used for repairing slight scratch marks on cars paintwork.

Hi,
Did you try using the white sponge magic eraser that can be had in large supermarkets or on line, they are not expensive and might do the job.

I'm not sure whether the silver units are painted anyhow , much like alloy wheels on cars? If so then techniques for getting alloy wheels back to looking new might be relevant-ish.

It is the black plastic scoop behind the array where the scratch is not the array itself

Ah sorry, I understand. My 212s didn't have the scoop.

As stated in the above posts, removing the 3K Array from the speaker cabinet is very easy, but as stated directly above don't even consider trying to dismante the 3K Array! Ages ago, I asked Linn about dismantling a pair of 3K Arrays in order to fix (or replace) the bashed-in meshes (fortunately for me, not my own ones) and I was told that whilst they can be taken apart if you know exactly what you're doing, it's something that should only be done back at the factory (i.e. by someone who has done it before) as it's very, very easy to destroy the units in the process. I can't remember the exact details (it was a while ago) but I remember that there were actually several nasty traps including an issue with damaging the gasket, and then another key issue where you have to carefully separate the super-tweeter from heat conductive pads between it and the back of the casting (or the super-tweeter will be totally destroyed when you pull the casting away from the face plate). I recall that were yet another few concerns including ease of wiring damage and also the ease of reassembly without trapping wires, so despite the fact I've done some relatively tricky technical jobs over the years, I remember reading all the pitfalls and immediately deciding that there was absolutely no way that I'd even want to try it as the likelihood of me damaging them was too high. It really does sound like one of these tasks where you want to have someone who's done a few of them before (and even then, to also have the backing of the factory parts bins in case it still goes all wrong).

Edit: Due to a long phone call, I pushed the submit button before seeing the other posts had clarified things (it's a scratched scoop). That said, I'll leave my dire warning about not dismantling a 3K Array; you never know, it might - sometime in the future - prevent someone else from trying and thus damaging their units. Smile

3k arrays are a surprisingly reasonable cost to replace completely anyway, so there's no real reason to disassemble.
