Just trying to figure out if this is something I can fix or get fixed. 11 years old, has worked flawlessly. No power light and no sound. Replaced it with another (borrowed sub) and got sound. I'm not a techie by any stretch but am fairly handy. Any suggestions would be much appreciated.
Unless it is an easily accessible fuse, probably forget it. HSU Research and others make subs for 300$up which are fine HT/Music subs. If this sub has a plate amp, it MAY be feasible to purchase a new amp and replace it...but then you are dealing with a driver that has had over a decade of presumably hard use........
I have an itch to say "build your own," but sadly, most aren't willing.
I'll simply -try- to explain it succinctly.
There are many people who would design one for you free (they just do it in their spare time, and they know a lot) based on your preferences, then send you the info on how to build it. You can get a LOT for under $1000 self-built. I've experienced the results. Of course, most aren't willing to go that route.
... There are plenty of options in that price range (probably one of the MOST competitive price ranges for subs these days).
There's SVS, HSU, ML, and many others I would easily recommend.
SVS is probably better for movies IMHO. HSU is good for either one. ML is also good for either one, but according to my ears, tends to excel with music. I listen to a LOT of music. I've probably listened to over 60 hours of music already this week.
I have nothing else to add, except I hope you make an informed decision based on your preferences of material (movies, music, what have you).
