The ported factor on the 8 actually is very helpful. Its not the tightest bass in the world but it definitely does the job for most music. Only disappointed on a few tracks here or there, but I have one in a medium size room and it is very surprising. Having said that, I would only use it for music or TV only environment. I would never use it for HT. It also has pretty good musicality, the 10 doesn't seem as musical for some odd reason. I only have my 8 turned up to about 3/8ths in a two channel set up, and it does a good job... would I rather have a rythmik... sure, but for about 100 bucks, I don't know if there is a lot that can compete with it- even some of the budget 10/12's don't sound as good. imho. I think that's why Jones puts his name on it, because for what it is, its pretty good... but I think its marketed in a silly way (for HT and such).
