I'm not in a hurry to do a setup just yet, but I'm not familiar with brands and such, what's good and what isn't. Now, I keep playing with winisd and I've learned that watt for watt, two subs sealed in a given box volume is, to me, inferior in output to a single sub in a ported or bandpass enclosure. I like to compare to 2 subs sealed because that's what I used to have. It gives me an understanding of what to expect. But I don't know (never did) too much about brands and such. It's been like two years and I don't know what's going on. Point me to one 15" that can get retarded under 60-70hz, in around a 4 cubic foot ported box tuned to 31-34hz, taking up to 1,500wrms........and around $200-$300. How about something in a 4th order bandpass? Something in a 4-5cube box giving me +3db at 35hz and +3db at 55hz with a decent peak in the middle.
