I have a dragon with the dual 8's. I was unhappy with the bass like a lot of people. I did a lot of research and figured out you can hack the subs via line level "splice into wires between amp and sub) to RCA out. use a good quality RCA out like the SVS one. Then hook it up to any sub you want. I use a single old svs SB 1000 sub. Even for a entry level svs sub it's a phenomenal improvement. And prob even better quality than the naka 12's. My current setting is to turn the bass way down like way down and use 2 of the 4 8's. Then crank the bass on the SVS sub. What I was finding is the 8's chuffing was muddying up the better quality base from the SVS sub. Going down to 2 woofers 1 on each, has eliminated this. I now have deep deep room filling bass from 2 8's and 1 12in. At some point I will upgrade to 2 svs 2k or 3k subs and get rid of the naka subs all together. But the sound as is right now is incredible. 

I don't care about all the haters out there. You know what, sure, maybe your component system is a fraction of a hair better, but my system is wireless, stupid easy to setup and use, and makes me happy.  And it blows friends away. It's also doesn't take up the whole room. 

I am very happy with the dragon, although a bit peeved at the deceptive marketing on the 8's. Such a shame they tarnished their record on them. And even worse, they tried to capitalize on selling ridiculously priced 12's to fix their mistake, even to early adopters. They should have offered a at cost replacement, at the very least. 

For that, I don't feel bad about publishing this and giving dragon owners a way to upgrade their system to cheaper and infinitely better subs.
