Rilla, How do the Dayton drivers compare to the SI? As you actually use both seem to be the one to ask. I plan on building sealed subs this Fall, and either will work in the encloses I have designed (4 cu ft, a compromise between power handling and low end excursion). Decided against dual opposed so I have more flexibility in placement. Eventually I want 8 of them, this forum is going to lead to spending to much on HT. Now I am looking into making a front wall with transparent screen, but that's down the road. Would be nice to have a wall of subs hidden away unnoticed until called upon, the sniper approach.
