I am trully buffaloed on what to do about a sub. At first, I had my heart set on a Shiva. Then, I found the SAE 1204 which is very similar to the Shiva, only cheaper. Then, as I was showing my wife (who is kinda against the sub building project anyway) the SAE 1204 she seen the AV12 and thought it looked like a higher quality sub. As I told her, it is better, but it is a bit more expensive (I'm on a tight budget). So here is my dilema: Should I stick with the 1204 or spend a little more and go with the AV12. Of course for the price of the AV12 I could get a Tempest, though I am looking for a smaller box so the Tempest is probably out of the question. Here are my wants for the sub: detailed, accurate, can play deep and do it loudly. I had a vented box in mind, about 85 l - 95 l size. I would also like to use something like the PE 250 watt amp to be cost effective. Thanks for all your recommendations.
