I've owned my pair of ACI Titan subs (12" driver; plate amp) for many years, continuously powered on, and have not had any issues (knock on wood). However: I am no bass freak, their freq. response are set with intent of being flat; I don't use them for HT, only 2-channel music; peak volume rarely exceeds 95 db; and while I play most all music genres I rarely spin any rap, electronica, or other bass-heavy type music. In other words, never abused or pushed to their limits.
Subwoofer failings and their use-related reasons
Inspired by the current thread "My JL Audio sub is dead. What exactly happened?," I’d like to ask more generally (i.e.: not brand specific; but you are free to answer brand specific if you so desire) about any experience-based, typical correlation between the type of use of subwoofers (I’ll make no distinction here between home theater subs and hifi dittos) and their malfunctions. The weak link in particular appears to be the plate amps mounted in the subs and blown capacitors here, and this has a tendency to happen within a few years - irrespective of the type of use, it would seem. Please correct me if I’m wrong on this.
But what about the drivers? Much has been said (theorized?) about the strain put on these units with their excursion abilities in some cases approaching 4" and the significant mechanical and thermal "stress" that follows. However, in practical use - even among the most ardent of cinephile bass-freaks - what does actual experience tell you? Unless the drivers are "blown" thermally and/or mechanically damaged, does years of more or less heavy use eventually wear them out, so to speak? Please chime in.
