Long story short
a Soundsplinter owner is complaining that his sub is not loud enough for him, so all the possible wiring issues were addressed and the final verdict was that the sealed box he is using is simply not appropriate for his musical tastes.
He refuses to believe this and states that the sub should sound good in any box regardless of size and type and that a switch to bigger or ported box cannot possibly make that much difference.
Mike from Soundsplinter has chimed in several times trying to explain what to do.
A couple other Soundsplinter owners have also joined is complianing that their sealed Soundsplinters are sounding too quiet.
None of them believe that a different enclosure will help them and that it is the quality of the sub itself to blame.
we need some pros with some fresh typing fingers in there to set them straight.
