JP, nice picture. I want to build the RS8 hopefully in the next year. Is that bottom "circle" a driver or a port? If it is a port, is it the only one in each speaker? I thought of going ported as well but planned on seperating the enclosures in half and putting 4 mids and tweets in each w/ a port for each half. I've heard that it is better to avoid long internal dimensions if possible. Also where did you get a port w/ that big of a diameter? (seems bigger than a 4" flared port but that might be my misjudgement). I like the look of it (how it matches the drivers). I would consider doing the same thing but putting my 2nd port on top to mirror the bottom. Other than building a ported enclosure did you do anything different from Rick's design?
Once again, nice job, it really makes me want to get started on my own.
