I'm thinking of doing a sealed 18" build with the Dayton 18" HO. I want to use either the iNuke 1000 with dsp or the Crown XLS1000.
My only concern is low end output from using a sealed enclosure. I want the in-room response to be fairly flat down to 15hz or so (or as low as possibly really).
Looking at the article about this sealed 18" setup on Data-Bass has me very impressed. I'd basically go with the same configuration as I'd aim for a 4.2 cubic foot to 4.5 cubic foot build. I see the output below 20Hz is very strong, i'm just not sure how it would perform once I place this thing in my room.
I know there may be some natural room gain around 25Hz or so and down, just I don't know how much, or if it would leave me with satisfying output at these lower frequencies.
Can someone with experience with large sealed subs help me out here? Do you think this sealed 18" build will provide satisfying low end frequencies? (Satisfying relative to what i'm using now, a Bic F12 that goes to sleep below 27Hz). Also, will I be able to eq a fairly flat response down to the lower frequencies with the on board eq'ing systems of the amps I mentioned?
