I have the lowest line of 6 1/2's. While the tweeter is great the mid range isn't as clear as I would like. The old driver is very cheap looking and right now I have one new driver and one old one because that is all they had to replace the one that blew. Of course I'm no expert in tuning either, so that could be the issue.
Anyway, back to topic. I wonder why they have the RMS for the Assassin 12 listed as 350 but recommneded for 250? Looks like some competition for the RE series for the price.
pricing is ok. remember the assassin is their entry level sub as I recall, about on par with RE's RE line.. so the prices are about where they belong now. Still, good subs though, just don't expect an assassin to outperform a sub meant for high performance applications.
Xmax isn't really the cause of distortion. Motor control or lack thereof has more to do with that, as does the overall speaker/motor design and implementation.
That statement is a little broad or blanketing to be fair.
