I found this old thread and thought I would post here
I have the exact same situation as the OP did.
I have had the same awesome HGS-18 for 12 years too !!
Mine started making the same clicking and popping noises you describe.
I made a video of mine FOUND HERE
I saw in this thread a link to an MP4 video (Post #58), but that link is now dead.
I would love to see that video. Is there another link to it?
Did you ever get your sub repaired by Velodyne or buy something new?
I am looking for a new sub too, but if it can be repaired, I like that.
My budget is $4000 MAX, which can cover most any sub these days...except a Velodyne DD18+ @ $5800
That is just way overpriced...IMO
If it can't be fixed, I am interested in converting it to a passive sub with external amp
Can someone recommend a good amp to use for this sub driver?
Also, does anyone know how the sealed JTR Captivator S2
(Dual 18's @ 4000W) would compare to the HGS-18?
Room size is 29 x 21 x 8
I have posted in several threads about this, so some may have seen this question, and already answered.
Sorry for posting in multiple threads about the subject, but just trying to make the best decision
