After being talked into a DIY sub as opposed to a cheap Sony, (see this thread) I'm ready to get into the design process. I'm planning on running over to PE to pick up the 300-794 plate amp while it's still on sale for $125. Can everyone agree that this is the best I can do for this price as far as an amp is concerned? As for a driver, I was planning to use the Dayton 12" DVC as recommended by Jack Gilvey. In fact, I was planning on making a sub very similar to the sub Jack made (see this thread). After re-reading that thread though, I read where Jack said: "Comparing the Dayton DVC with the Shiva (both of which I own)in a sealed box ,it looks like the Dayton needs a smaller box for a given Qtc, but the Shiva will go a bit deeper for the same Qtc (in a larger box). Either woofer has excellent excursion, power handling, and SPL capabilities. If you wanted something very small, the DVC is excellent. If you can go to a net 2.2ft^3 or so, I might opt for the Shiva." This is directed mostly at Jack, but anyone who has an opinion, please chime in: Do you feel that a 2.2 cf box with a Shiva driver would be a better overall sub than a 1.2 cf box with the DVC? This is my first DIY speaker and I am going to have to go on what you guys tell me, but I want to do this right the first time around. This sub will be used both for HT and music (maybe 70% HT, 30% music). I am looking for a sub that's not at all boomy. I want tight "clean" bass and the best "overall" sub with that in mind. What do you guys think? Shiva or DVC? I don't mind a larger enclosure if I were to go with the Shiva (it could still be only 18"x18"x18" which isn't too large). Any opinions would be greatly appreciated.
