I ended up selling my htib as the speakers were a hair too large, woofer was ridiculously too large, price was right. That energy set looks tight, but of course the question is, how small is it? Is there a way I could use the existing woofer in the set? What would be a good spot for a woofer in a 30' boat?
Now since this thread was warmed back up, the thing I really came to say is, I'm seriously considering a projector. Hear me out... LED projectors are hitting the market, so hot expensive power hungry short-lived incandescent (or whatever) bulbs are out of the picture.

It's from isival, they have like two products including this one. It's basically 720P high def, but the brightness is nothing compared to a conventional projector. But for the spaces inside a boat, this machine might just be enough for what i need, to throw a 60 inch diagonal picture with just 30 watts. The brightness may be a deal breaker, but I'm very excited for the future of LEDs, and this has got me thinking of shipboard projector screens.
For a screen, would I fab my own with drapery backing, a dowel rod, and something to stretch it out? Buy some pre-made roll-up that mounts permanently to the overhead? I could be a real poseur and hank and tension the screen like a sail.
For sound, I'm coming to a conclusion that a receiver is out of the question. It comes with a mess of functionality that I don't need anyway. Audiophiles forgive me, but it seems that the best solution would be computer styles speakers, driven by 3.5mm jacks. I could pick up a 5.1 usb sound card, plug it into the laptop and rock out reasonably simply. I've been spending months looking for compact hdmi 12v marine receivers, or any 2 of the 4, and the search is a fool's errand. HDMI or DVI or even VGA straight to a monitor or projector and that's it. If I had unlimited time I'd run USB through the boat, to plug the laptop into all peripherals wherever I'm using it.
