    Tell us about reveering. Do you just fill and sand the dings and overlay the old veneer or strip it off first?

    How, how, how?

    As you can see from my avatar, the Hartsfield I own is in piano black refinished by a piano company in Atlanta, GA shortly after I bought it around 1959. Originally mahogany. I was into an oriental white and black furniture theme at the time. Changed out the grill to white to complete the theme.

    OK, That is nice, but...

    I saw a pair in rosewood once that have really stayed with me.

    Somehow though, a Hartsfield in piano black is different from an Aquarius IV. Also it is amazing that you have had the speaker for some 45 years. I wonder if that is a Forum record! Very Cool!

    Progress Report

    Sorry folks, it's been a while but the Aquarius IVs are making some slow progress. The cabinets have now been reveneered and all the sides have been sanded and fixed up. A new reveal has been routed for the base.

    Here's a full shot of the cabinets - before and after, ready for finishing:

    One more

    This was one of the worst corners, particularly water damaged and the joint had opened up:

    I'm back...

    I was always kind of disappointed when I was reading posts on this board and saw a thread where someone was working on an ambitious project and the the thread just died, never got to hear how things worked out. And then I went and did it myself.

    I started this project 11 years ago (almost to the day) but stopped posting after only a month or so. In my case it was a combination of things, mostly it was because I started a new job and didnt have time to keep working on these speakers, but it was also a matter of hitting a major snag and getting discouraged.

    Well I am back to the project, and actually have been making some good progress, I have overcome my snag - issues with the reveneering - more on that later.

    Over the years I accumulated a second pair of AQ4s and a few important parts for this restoration project, I will be adding some posts to walk through all of the sub-projects as I work through them.

    Start from the beginning of the signal.

    As I restarted this project I first took on dealing with some of the internal components, here are pics of the crossovers before and after. You'll notice some strange stuff going on here. One of the crossovers had either been repaired or maybe reworked by the factory. It actually shows markings that it might have started out as an LX-12-5 crossover, but the crossover for the AQ4 is an LX12-7. You can also see that the wax cup was opened up, what you can't see is that the coil had been replaced. For some reason they then used that expanding insulation foam instead of wax for the repack.

    I replaced all of the components in the crossovers, the capacitors for obvious reasons, but I also replaced the coils, the one that was in the repaired crossover was wildly out of spec (44mH instead of 2) I'm not sure why it was wrong, it had the correct markings, maybe it was damaged at some point, maybe my heat gun did it in when I removed it.

    The second pic shows the new components in place, the last pic shows the crossovers after I refilled them with fresh bees wax. It all looks much tidier now.

    I also replaced the L-Pads with new old stock exact replacements, plus a couple of new sets of genuine JBL push connectors.

    Thanks Odd, I saw your thread - that had a lot to do with my getting back to this project. Your pair looks wonderful.
