In the recent Parts Express flyer, they're advertising a sub kit using the 10" Titanic and a 250W amp. The kit comes with finished 3/4" MDF and some really cool looking spikes. The cost is $349 with all the parts included and is listed as a "1 hour kit". You can see the kit here --enter part number 300-739. While I'm not arguing that this is in the league of the big time projects put together here, this might be a nice alternative for someone that wants better than commercial performance, but doesn't want the full DIY experience. What do you think?
