Right, I don't think I have really exped a "better" sound out of a cheap speaker in a box like my sub, or even an expensive sub.
But wow that sub, 4k and 115lb - lets quote Jurassic Park (that I am sure sounds awesome on that! haha) "If its heavy, its expensive!" lol
So I think I am mostly where I was on the sub thing, anything that I am going to buy - 100-200$ is not going to be significantly better than the little Sony that I already have.
Nor do I think my amp is going to drive anything super crazy, its just a Denon 5.1 - and my surrounds are polk OWM's - I had TSi's but the wife wanted a streamlined look so I did a 7 speaker setup on the walls with crown hiding the wires heh.
-- As for the arcade set up. I got retropie on the rpi3 easy as cake. I think getting the MAME roms working properly may be a different story - I haven't finished making my controller setup - I just cut and assembled a beta idea of what I wanted - and its not done yet - so I have not used the arcade buttons on the rPi3 yet.
I am going with more of a bench that's able to be used while an adult is sitting at the couch - younger kids it would be like a stand up. and with 2 players.
Anyone happen to have a torrent for some nice roms, the one I downloaded the SNES ones were all jacked up file extensions and didn't work and the MAME is kind of confusing... the roms are not individual files? Not that I have looked into it that much.
Also, I am just going to build the Rpi3 into the controller bench thing... a long USB was 4$ a long HDMI is 6... and simpler to just plug in a HDMI and go- ill have to wire some power also into the final version of the game table.
