I'm sure one could custom make an enclosure, as we've talking about, and
get better sound, but at what cost? I think I'll be quite happy with the
SBS-05C.

That's very cool. I should know that Alpine rarely ever makes crap. The
problem is that now I must consider this as well, damn, more decisions! How
much are they asking for it? I see Crutchfield is asking $149 which isn't
bad at all. Hmmm...

Let me know how it sounds when it is installed in your system.
