I decided if I don't do anything, I won't ever get a sub built.
So I've decided that I will order a driver within the next week or two.History:
Within the past years I've had different designs, but I never managed to get the money together. One time it was 8 Aurasound NS18s when I thought I was going to be able to do that. Of course, I never got the money together. It was once 4 Fi 18s (one per corner), before the NS18 thought. Now I'm back to a single 18" driver.Basic idea:
My current plan is to use a single Fi Q18 (maybe with a small change, depends on the e-mail I get back) in a large enclosure with a tuning around 13-15 hertz.
The source of power will start out as my old receiver (probably 200-250 watts) until I can afford the next part. If I decide I want more even response with a bit more SPL (or less distortion), I will build a duplicate of the original enclosure and use more channels to get 400-500 watts and place them to get best response. If I decide I just want it louder, I will buy an amp to bring it up to about 2kW. Then after that, I plan to bring in the one I didn't do first (so if I decided on the amp, I'd build the second sub).The Area:
The full area I will consider this to be filling is about 8000 cubic feet, but the listening area only takes up a third of that. The current speakers all have 12" woofers and I am currently planning to do a crossover around 60hz. I am using a Pioneer Elite VSX91-TXH for the receiver (which was bought with the store credit of a blown sub I returned).
It's better to have a single sub on limited power than no sub at all. Tastes/Material:
Usually I'm listening to music, but a movie tends to creep in every other day. The music is usually metal, such as Metallica (and KoRn), but I listen to a lot of different styles.Current experience:
I am unimpressed by the low end on my system, and music sounds thin. In movies, the explosions are there, and I can feel gunshots etc.. but it's obviously missing the sub 30-35hz content and sounds thin.
Any suggestions are welcome on these decided things, although I may or may not take them to heart.
The box plan is 2x3x5 (driver on 2x5 side, sub standing on 2x3 side, port likely on top). The current plan is to be able to hook the driver up in different coil configurations on the back of the cabinet, to make things easier.
Current undecided/unknown things: Cloth for cover, build difficulty, exact EQ, safety of pictures on wall.
