The A7S-450 is a lot of subwoofer for the money. It performs well, blatting out a lot of deep bass, but not at the expense of musical nuance and subtlety. Contrary to its considerable size, it is also fully capable of disappearing, sonically, blending well in a properly calibrated and tuned system, handling quiet bottom end detail, and belting it out when called upon without giving it position away. That is unless you look at it; then the A7S-450 is hard to miss. If the room to board this beast is available and the wife won’t kill you for bringing it home, it is definitely a worthy subwoofer to consider at anywhere near its price point. Highly recommended!

I don't know if they will still do this: You may be able to request that they ship you the sub unfinished.
Yes they do and they will customize box dimensions to meet your needs. When I started looking at replacement subs last month two of these were on that initial list and Alex (I think?) was very helpfull via e-mail.
A dual voice coil subwoofer. By the way he was describing the driver it seemed as if he had never seen one before. The 19Ov.2 was originally designed for car audio applications and having dual voice coils allows for more wiring options. He says "There are two pairs of wire terminals located at opposite sides of the driver, apparently to allow bi-amplification for car usage." I was kind of suprised to read that to be honest, I don't know of too many people using an amp for each voice coil. I think it should be edtited to avoid confusion. Other than that it was a well written in depth review, I hope to see some of eD's others subs reviewed because I would like to hear how they stack up against the competition.
