Went Full Retard

[Umbra]

A short anecdote/rant good for little more than a laugh.

I've got these pair of RFP He2s. One's fine - It's a ******* champ. The other is.... problematic. When I bought them used the one had a failed connection between the leads of one coil. I cut the dustcap off it and saw the connection from the tinsel to the coil had severed, so I tried soldering it with the little bits that I could access, put some hot glue over it, stuck the cap back on and reinstalled it. It worked, for a couple months, then the problem came back. Cut the thing open again and to my surprise the problem is with the other coil. Did the same fix with a slightly modified technique (twisted the bits upwards in parallel, rather than perpendicular to one another and added heat shrink tubing). Rather then stick the cap back on with CA glue I used Gorilla glue. I had a bit of excess seep out, but I cut it off. I reinstall it, it works for a couple months, bam! Problem comes back a third time. I hastily cut the dustcap off for a third time, but the puffed up Gorilla glue threw me off. I'm cutting and all of a sudden I'm seeing spider. I ended up cutting through the entire circumference of the cone! The ******* dustcap didn't even come off (it did with a slight pull though). Turns out one side of the tinsel-coil connection came undone from the first fix. I'll see if I can patch it up once more and maybe fortify the other one while I'm in there.

I reattached the two pieces of the cone with Amazing Goop. I'm going to let it sit a couple days to reach full strength. I'll address those connection issues while I wait on that. It's a relatively nice sub. Looks sharp, built nice, sounds nice. It's nice to me, but I know a lot of you would laugh at 400W RMS). If I can fix it, fantastic - I can keep the pair, but I don't think it's worth sending off to be professionally reconed and the connection issues fixed. In a couple months time I'd like to replace them with something like an AB XFL 12 anyway.

I might try crimping the connections this time around. Can anyone link me to such an object? Do you think a good Amazing Goop connection would hold up on 400W RMS? Is there anything I can do to strengthen that bond, like gluing a patch down?

sounds like its recone time

or you can see if you can get the cone off and replace just the cone

If this doesn't work I might go that route. I've never done a recone, but that might fix the connection issues too if those parts come with it (I'm not sure, I did like three minutes of research). I think this would fall into the sweet spot where it's not too valuable to experiment on, but not too cheap it's just not worth bothering with.

They arent' worth reconing in the long run, IMO. Just sell it on craigslist or hold onto it for now and save up for an upgrade

if they were hx2s i would recone them, he2s arent that great

What was the difference between them? I haven't look into it too much, but I thought the main difference was an extra 100W of power handling.

I let the Amazing Goop cure for three days and put some power to it and it looks solid. I put some more over the internal connections and Gooped the dust cap on last night. I'll install it alongside the pristine one and try out the BPX 500.1 on the pair and see how it goes. If it hold up I'll use it for the foreseeable future. If it doesn't I'll buy a single sub and stick it in a ported box.

less excursion, less power handling, more im sure. Ive used both. the 12 he2s bottomed out quick with any power
